Dietary fat intake and lipid profiles of Iranian adolescents: Isfahan Healthy Heart Program--Heart Health Promotion from Childhood.

OBJECTIVES: To assess the serum lipid profiles of Iranian adolescents and their correlation with dietary fat intake and to evaluate the knowledge, attitude, and practice (KAP) of students, parents, and school staff. METHODS: The subjects of this cross-sectional study were 2000 students (1000 girls and 1000 boys), ages 11-18 years, selected by multistage random sampling, and one of their parents (2000 subjects), as well as 500 school staff in urban and rural areas of two provinces in Iran (one for further interventions and the other for reference). The data were obtained by questionnaires, anthropometric measurements, 3-day food record form, and a 20-item food frequency questionnaire (FFQ). All serum lipids were determined in the same laboratory. RESULTS: Although the percentage of fat intake (21.2 +/- 0.4%) among the adolescents was within the recommended daily allowance (RDA < or = 30%), in most cases, the percentiles of serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglyceride (TG) were significantly higher and the percentiles of high-density lipoprotein cholesterol (HDL-C) were lower than standard values according to Lipid Research Clinics (LRC) data; for example, the mean TC values for girls in the 11- to 14- and 15- to 18-year age groups were significantly higher than LRC standard values (169 and 172 vs. 160 and 159 mg/dl, respectively, P < 0.05). This difference was also significant in boys (167 and 168 vs. 160 and 153 mg/dl, respectively) at the P < 0.05 level. A significant linear association was shown between adolescents' dyslipidemia and the frequency of intake of hydrogenated fat, fast foods, cheese puffs, and potato chips (P < 0.05). Although the protein intake was lower than the RDA (13.4 +/- 0.9% vs. 15%, P < 0.05), because of the highly prevalent consumption of fatty lamb meat, the frequency of red meat intake had a direct association with dyslipidemia (P < 0.05). CONCLUSION: The improper intake of high amounts of saturated fat and the observed serum lipid profile of Iranian adolescents are likely placing them at increased risk for cardiovascular disease (CVD) and necessitate developing guidelines and community-based interventions.

Body mass index in elementary school children, metropolitan area food prices and food outlet density.

OBJECTIVE: The aim of this study was to examine the association between food prices and food outlet density and changes in the body mass index (BMI) among elementary school children in the USA. METHODS: The Early Childhood Longitudinal Study followed a nationally representative sample of kindergarten children over 4 years. We merged individual-level data to (a) metropolitan data on food prices and (b) per capita number of restaurants, grocery stores and convenience stores in the child's home and school zip code. The dependent variables were BMI changes over 1 and 3 years. We analysed mean changes with least-squares regression, and median changes and 85th percentile changes with quantile regression. We controlled for baseline BMI, age, real family income and sociodemographic characteristics. RESULTS: Lower real prices for vegetables and fruits were found to predict a significantly lower gain in BMI between kindergarten and third grade; half of that effect was found between kindergarten and first grade. Lower meat prices had the opposite effect, although this effect was generally smaller in magnitude and was insignificant for BMI gain over 3 years. Differences across subgroups were not statistically significant due to smaller sample sizes in subgroup analyses, but the estimated effects were meaningfully larger for children in poverty, children already at risk for overweight or overweight in kindergarten, and Asian and Hispanic children. There were no significant effects for dairy or fast-food prices, nor for outlet density, once we had controlled for individual characteristics and random intercepts to adjust standard errors for the sampling design. DISCUSSION: The geographic variation in fruit and vegetable prices is large enough to explain a meaningful amount of the differential gain in BMI among elementary school children across metropolitan areas. However, as consumption information was not available, we cannot confirm that this is the actual pathway. We found no effects of food outlet density at the neighbourhood level, possibly because availability is not an issue in metropolitan areas.

Home use of margarine is an important determinant of plasma trans fatty acid status: a biomarker study.

The contribution of the home use of margarines, made with partially hydrogenated vegetables oils, to total trans fatty acid intake is difficult to determine using dietary assessment because food composition databases are incomplete for trans fatty acids; moreover, hidden fats in manufactured foods may be the predominant sources of trans fatty acids. The objective of our study was to determine, using plasma phospholipid trans fatty acid composition as a surrogate measure of exposure, whether the home use of margarine or butter is an important determinant of trans fatty acid status. We conducted a community-based (Dunedin, New Zealand), cross-sectional survey of people who consumed either margarine (n 65) or butter (n 64) but not both for home use. The levels of the 18:1 trans isomers commonly found in partially hydrogenated vegetable oils were all significantly higher in the plasma phospholipids of margarine compared with butter consumers, with the exception of 18:1n-7t, which did not differ. Among margarine consumers, the percentage of total fat from margarine was significantly correlated with levels of phospholipid 18:1n-6t, 18:1n-8t and 18:1n-12/9t isomers (r 0.57-0.63, P<0.001) but only weakly with 18:1n-7t (r 0.30, P=0.016). The intake of fat from fast foods, bakery products or meat and meat products was not associated with plasma phospholipid trans isomeric composition. The home use of margarine, made with partially hydrogenated vegetable oils, is an important determinant of trans fatty acid exposure in New Zealand.

[Minor salmonellosis in childhood: epidemiological and preventive considerations].

The diffusion of so-called minor salmonellosis in Italy, 18,135 isolates in 1985 -and the serious illness that they may induce in correlation to age and state of health have moved the Authors to consider their epidemiology and discuss their prevention. The morbidity per 100,000 population, from about 10 in the early '70s, has grown to a peak of 22.22 in 1976 and, after having irregularly reduced to a value of 16.76 in 1984, has grown again to 22.23 in 1986. Travelling abroad, modern breeding technologies, animals and raw food trade among States are frequently indicated as the most important factors in spreading salmonellas. The rise of morbidity in Italy has indeed occurred in concomitance with the renewal of breeding activity realized by means of animals imported from abroad, and moreover, presence of strains of S. typhimurium identical to those which caused serious epidemic outbreaks in bovine and humans in Great Britain and other Countries of North Europe is now ascertained. Recently, cooked ham prepared with raw meat contaminated with two serotypes uncommon in Italy (S. corvallis and S. mbandaka), imported from Rumania and Holland, has been the cause of two foodborne outbreaks each showing both of the above contaminants. At present, salmonellosis is quite common in large urban areas and is supported by person-to-person spread; more than 50% of the yearly isolates occurs in childhood Number of cases, their ages, sex distribution, and relative morbidity, have been calculated in Tab. 1, 2, 3, 4. From 1976 to 1986 the withdraw of S. wien, the research of excretors, and the improvement of quality of life, are all factors that may have favoured the lowering of morbidity at age zero, while the increasing of the same index at the ages 1-5 and 6-10 may correlate to the high number of serotypes of Salmonella now endemic in Italy. The diffusion of fast-food and the habit, recently acquired in our Country, to buy at shop cooked foods ready to eat, may be involved too. Age distribution shows a highest number of isolates at age zero and a still high number at ages 1, 2, and 3. Throughout childhood morbidity is lower in females. From 1975 on, the percentage increase of number of children admitted for minor salmonellosis is also indicated by surveys held at many Hospitals in Italy.(ABSTRACT TRUNCATED AT 400 WORDS)

Use and misuse of automobile child restraint devices.

OBJECTIVE: To determine demographic, social, and behavioral characteristics that are associated with correct child restraint device (CRD) use. DESIGN: Cross-sectional. SETTING: Fast-food restaurant parking lots in southeastern Michigan. PARTICIPANTS: Children younger than age 4 years and their drivers. SELECTION PROCEDURES: Consecutive sample. INTERVENTION: None. MEASUREMENTS/MAIN RESULTS: Seven hundred seventeen child passengers were observed for 11 dimensions of CRD use and 661 of their drivers were interviewed. Three hundred ninety-four (55%) of the children were in CRDs, but 248 (63%) of those children were incorrectly restrained. A 43-point misuse index was constructed based on scores assigned for different types of misuse. Seven variables (ie, age of child, race of parent, driver as a parent, days driving, number of occupants, perceived comfort of CRDs, and belief that the social norm supports CRD use) were highly predictive of CRD use. In contrast, only three factors (ie, age of child, education of the driver, and knowledge of the CRD law) were minimally predictive of correct use. CONCLUSIONS: Since correct use of CRDs represents such a complex behavior, the best strategy to address the widespread problem of CRD use may be through the design of less complicated CRDs.

Obesity and eating style.

Eating styles of 30 obese women and 37 matched women of normal weight were observed unobtrusively in a fast-food restaurant in the search for an "obese eating style" or other differences between the two groups. The size and character of the food was carefully matched by giving each woman a coupon entitling her to a free meal of either 985 or 1,800 calories. There were only small and inconsistent differences between obese and normal-weight women. No evidence of an "obese eating style" was found.

The relationship between work permits, injury, and safety training among working teenagers.

BACKGROUND: No information exists on the differences between teenagers with work permits and teenagers without work permits in regards to workplace injury, near-miss incidents, and safety training. METHODS: In May 2003, an anonymous questionnaire was administered to 7,506 teens attending high school throughout the five public health regions of Wisconsin. All students in the participating school districts were invited to respond. The questionnaire included questions about employment, injury, safety and health training, and school performance. RESULTS: Overall, 6,382 teens participated in the survey and 49% reported working during the school year. Seventy percent of all working teens reported having a permit. Females were more likely to have work permits compared with males (71% vs. 68%, P = 0.018). The percentages of teens with permits varied by job and ranged from 55% for teens working in tree-trimming/cutting to 85% for teens working in restaurants or fast food establishments. Teens with work permits were no less likely to be injured than those without permits (AOR = 1.07, 95% CI: 0.85-1.33) and no less likely to have a near-miss incident (AOR = 1.28, 95% CI: 0.99-1.63). However, teens with permits were significantly more likely to be given safety training than teens without permits (AOR = 2.61, 95% CI: 2.21-3.10). CONCLUSIONS: Although teens with work permits were more likely to report receiving safety training than teens without permits, the occurrence of injury was no different among the groups.

Congressional approaches toward remedies to problems of child labor.

Hearings by the Employment and Housing Subcommittee and nationwide "sweeps" by the Labor Department focused attention in 1990 on the growing problem of child labor. Fast food and retail establishments employ the majority of minors and were found to have the most violations. Although the bulk of violations affected hours of work (too many or too late), many involved prohibited hazardous occupations. Reform measures were introduced in the House and the Senate. They would limit hours of work during school weeks for 16-17-year-olds, require school work permits, improve protection of farm workers, increase civil and criminal penalties for willful violations, and provide for national reports on employment of and injuries to workers under age 18. As of May 1992, the Senate Committee on Labor and Human Resources has voted out its bill, but floor action has not been scheduled. The House Subcommittee on Employment Standards has taken no action.

A descriptive study of pregnant women with gallstones. Relation to dietary and social habits, education, physical activity, height, and weight.

Five hundred and twelve women attending the antenatal clinic of the Rotunda Hospital of Dublin were studied by means of abdominal real time ultrasound (US) scanning to establish some of the characteristics of those subjects found to be gallstone-positive, compared to the gallstone-negative control population. Coffee, tea and sucrose consumption, dietary fats, attendance at fast-food restaurants, education, cigarette smoking, alcohol, and physical activity did not show any substantial differences between the two groups, while there was a significantly higher prevalence of cholelithiasis in women who had been dieting and in overweight subjects.

A survey on operating conditions and quality of commercial frying fats in Hungary.

An extensive survey on commercial frying fats was conducted in Budapest. It was based on sample collection, analysis and questionnaires filled in with each sample. Frying fats and oils were collected from restaurants, fast-food services and public catering facilities. The quality of samples was assessed by determining their polar components. An evaluation of questionnaires containing over 20 questions yielded detailed information on the usage of fats as well as the fryer operators' habits of conducting frying processes and their knowledge on the subject. The survey consisted of two periods. During the first period 252 samples were collected at random. Quality assessment indicated that 53.6% of all samples was of good quality (with concentrations of polar materials below 25%) while the rest were at the discard point or deteriorated. The second part of the survey was aimed at a recheck of the places where fat had been found deteriorated. Second samples were obtained from 53 establishments. The results showed an improvement both in operating conditions and quality of frying fats. Based on the results, the necessity of instructing fryer operators and introducing regulations and routine quality testings of frying fats became obvious.

Lifestyle associated risk factors in adolescents.

OBJECTIVE: The data on these risk factors in school age population is deficient in India. The present study was conducted to evaluate the prevalence of lifestyle associated risk factors for non-communicable diseases in apparently healthy school children in an urban school in Delhi using standard criteria. METHODS: The study was carried out among 510 students of classes 9th-12th of a school in New Delhi and in the age group of 12 to 18 years. The students were surveyed through an age appropriate modified GSHS (Global School Based Student Health Survey) self administered questionnaire. Height and Weight were measured using standardized equipment and procedure. The blood pressure was measured using OMRON electronic B.P apparatus which were standardized daily against a mercury sphygmomanometer. The statistical analysis was done using Epinfo ver.3.3 and SPSS ver11.5. RESULTS: The study documents the inappropriate dietary practices (fast food consumption, low fruit consumption), low physical activity, higher level of experimentation with alcohol and to a lesser extent smoking, high prevalence of obesity and hypertension in the school children. The study also showed an association between BMI, systolic and diastolic blood pressures amongst children and other lifestyle factors. CONCLUSION: School based interventions are required to reduce the morbidity associated with non-communicable diseases.

Physical illness and lifestyle risk factors in people with their first presentation of psychosis.

BACKGROUND: There is an increased prevalence of physical illness and poor lifestyle in patients with chronic schizophrenia. It is unclear whether these are present at the onset of psychosis or develop over the course of illness. We aimed to establish whether patients experiencing their first episode of psychosis have worse physical health and lifestyle than community controls without psychosis. METHOD: Eighty-nine patients with new onset illness were compared to age and sex matched controls for self-reported physical illness and cardiovascular and respiratory risk factors. RESULTS: Patients reported more physical health complaints, mainly respiratory, compared with age and gender matched controls (odds ratio 2.85, 95% confidence interval 1.2-6.7). Patients were more likely to be cigarette smokers (1.82, 95% CI 1.0-3.3) and eat a fast food diet (1.04, 95% CI 1.0-1.1), but these differences were accounted for by patients' unemployment status. CONCLUSIONS: Some risk factors for physical health problems are present at the onset of psychosis, but these may be explained by unemployment.

Intestinal absorption of lycopene from different matrices and interactions to other carotenoids, the lipid status, and the antioxidant capacity of human plasma.

BACKGROUND: The bioavailability of carotenoids has been investigated in animal studies as well as in human studies, so far mostly for beta-carotene. Only few results exist for lycopene. In recent studies, lycopene was significantly better available from processed tomatoes compared to raw tomatoes, when using daily intakes between 16.5 mg and 75 mg lycopene. AIM OF THE STUDY: In a comparative study the availability of a low oral lycopene dosage of 5 mg/d from different food matrices versus soft gel capsules containing tomato oleoresin was assessed. In addition to the plasma carotenoid content, the effect of lycopene ingestion on other plasma carotenoids, the lipid status parameters, and the antioxidant activity was estimated. METHODS: Twenty-two female adults (20-27 y) were randomized in three groups and were advised to minimize their carotenoid intake for two weeks. After this initial period, two groups received a portion of tomatoes or tomato juice adjusted to a lycopene dose of 5 mg/d, the third group ingested the same dose comprised in soft gel capsules containing tomato oleoresin. During the test period of 6 weeks, the participants continued reducing the intake of carotenoids from food. Fasting blood samples were withdrawn prior to the study, before supplementation started, and then weekly while supplemented. Seven-day dietary records were prepared before the study started and after one week of supplementation. Carotenoids were analyzed by reversed phase HPLC with diode array detection. Dietary records were evaluated using the computer software EBIS 2.1. The plasma total cholesterol, HDL cholesterol, and triglycerides were determined enzymatically. In addition, the antioxidant activity of plasma was estimated by using the TEAC and the TRAP assays. RESULTS: The basal levels of lycopene in plasma were comparable for all groups (0.2-0.3 mumol/l) and decreased significantly during the two weeks of depletion to approximately 50% of the basal values. Other plasma carotenoids such as beta-carotene and beta-cryptoxanthin decreased significantly, too, whereas lutein and zeaxanthin remained unchanged. After supplementation with tomato oleoresin capsules or tomato juice, the plasma lycopene increased significantly, while it remained unchanged during intake of tomatoes. Normal dietary habits were practised of all volunteers before and during the study except vitamin C whose intake was significantly lower during the study period, because the probands were recommended to reduce the intake of fruits and vegetables. Lycopene supplementation did not affect the lipid status parameters of the three groups. After ingestion of lycopene the antioxidant activity of the plasma was not altered. Mean TEAC values were estimated to 0.33 +/- 0.05 mmol/l and TRAP values to 1.0 +/- 0.1 mmol/l and showed no significant differences in all groups during the whole study period. CONCLUSIONS: The bioavailability of lycopene varied significantly depending on the administered matrix. Lycopene from tomato oleoresin capsules and tomato juice (processed tomatoes) was better absorbed from the intestine than lycopene from raw tomatoes. The daily intake of 5 mg lycopene, an intake comparable to the usual daily carotenoid intake, did not affect cholesterol and triglycerides in plasma or its antioxidant capacity.

Asthma, eczema, and reports on pollen and cat allergy among pupils in Shanxi province, China.

OBJECTIVES: To study self-reported asthma, eczema, and pollen and furry pet allergy among pupils (9-20 years) in Shanxi province, China, in relation to dietary and environmental factors. METHODS: A standardised questionnaire was distributed to pupils in two primary and two secondary schools, one in Taiyuan city (3.0 milj. inhabitants), the others in Qingxu county, a rural area 30 km outside Taiyuan. Totally, 2,116 pupils (90%) participated. RESULTS: Fifty percent were girls, 61% had been growing up on the countryside, 18% lived in Taiyuan now, 1.7% had ever had asthma, 0.8% had doctor's diagnosed asthma, 1.4% pollen allergy, 1.7% cat allergy, and 0% had dog allergy. Multiple logistic regression was applied, controlling for age, gender, diet, indoor exposures, rural childhood, and current urban residency. Girls had less eczema (OR = 0.51; 95%CI 0.28-0.92). Pupils in the city had more eczema (OR = 5.05; 95% CI 1.11-23.3). Those with a rural childhood had less asthma (OR = 0.17; 95% CI 0.05-0.60), eczema (OR = 0.15; 95% CI 0.13-0.66) and pollen/cat allergy (OR = 0.50; 95%CI 0.25-0.99). None of the indoor variables was related to asthma or allergy. Children with frequent fruit consumption had less asthma (OR = 0.40; 95% CI 0.19-0.82) and pollen/cat allergy (OR = 0.49; 95% CI 0.29-0.84). Those with frequent fish consumption had less asthma (OR = 0.32; 95% CI 0.11-0.97). Those with frequent hamburgers consumption had more asthma (OR = 2.05; 95% CI 1.09-3.87) and eczema (OR = 1.85; 95% CI 1.12-3.04). CONCLUSION: Asthma, eczema, and pollen or pet allergy was uncommon, compared with western countries and other areas in China. Pupils with a rural childhood had less asthma and allergy, which is consistent with the "hygiene hypothesis". Fruit and fish consumption may reduce, and fast food consumption may increase the risk for asthma. Finally, the higher prevalence of asthma and eczema among younger children, born in the 1990s, indicates a cohort effect similar to that observed in western countries.

Characteristics of child safety seat users.

Direct observation of child restraint use was combined with interviews and mail questionnaires to measure prevalence of various child restraint practices and factors related to use of child safety seats and seat belts for children under the age of four. Trained observers assessed multiple dimensions of child restraint practices for a sample of motorists entering fast-food parking lots in Michigan. On-site interviews and follow-up questionnaires measured sociodemographic, attitudinal, belief, and behavioral characteristics related to restraint use. Ninety-two percent of infants under age 1 and 55% of children age 1 to 3 were traveling in a child safety seat. Public support for the mandatory child restraint law was very high--9 out of 10 believed it should be strictly enforced. Child restraint use was lower than average among motorists who: (1) had low family incomes, (2) were not currently married, (3) were of nonwhite ethnic backgrounds, and (4) were over the age of 40. A shift in social norms appears to have occurred in recent years, such that restraint of young children traveling in cars is now socially expected behavior. Recommendations include: (1) continuing educational efforts to increase knowledge of mandatory child restraint use laws, and (2) increased enforcement of mandatory child restraint use laws.

Abnormalities in weight status, eating attitudes, and eating behaviors among urban high school students: correlations with self-esteem and anxiety.

PURPOSE: The study's objective was to determine the prevalence of abnormalities in weight, eating attitudes, and eating behaviors among an urban teenage population. METHODS: Measures of weight, height, and blood pressure were obtained from 1,001 students attending regularly scheduled physical education classes in a New York City high school the population of which was 66% black and 23% Hispanic. The mean age was 16 years old; 55% were female and 45% were male. Approximately three quarters of the students completed the Eating Attitudes Test (EAT-26), Rosenberg Self-Esteem Scale, Spielberger Trait Anxiety Inventory, and a questionnaire on eating behaviors. RESULTS: By percent ideal body weight (%IBW), 25% of students were obese (>20% above IBW), 18% were overweight, and 5% were underweight. Abnormal EAT scores (>21), were found in 6% of males and 15% of females. Students reported that they had engaged in the following nutritional behaviors at least three times in the past week: eating candy (59%), skipping breakfast (58%), skipping lunch (42%), eating fast foods (28%), and skipping dinner (14%). Self-esteem was high in 60%, medium in 21%, and low in 19%. Mean self-esteem was significantly higher (P < .0001) than established norms. Self-esteem and anxiety were inversely correlated (r = .40, P < .001), and low self-esteem and high anxiety were both associated with high EAT scores (r = .29, P < .001). Self-esteem and anxiety of obese students did not differ from those who were of normal weight. CONCLUSIONS: Among this population of urban high school students there were: (a) a large number of overweight adolescents; (b) a significant subgroup with eating attitudes suggestive of an eating disorder; and (c) high levels of self-esteem and normal levels of anxiety, which were independent of weight status.

Potential effects of the next 100 billion hamburgers sold by McDonald's.

BACKGROUND: McDonald's has sold >100 billion beef-based hamburgers worldwide with a potentially considerable health impact. This paper explores whether there would be any advantages if the next 100 billion burgers were instead plant-based burgers. METHODS: Nutrient composition of the beef hamburger patty and the McVeggie burger patty were obtained from the McDonald's website; sales data were obtained from the McDonald's customer service. RESULTS: Consuming 100 billion McDonald's beef burgers versus the same company's McVeggie burgers would provide, approximately, on average, an additional 550 million pounds of saturated fat and 1.2 billion total pounds of fat, as well as 1 billion fewer pounds of fiber, 660 million fewer pounds of protein, and no difference in calories. CONCLUSIONS: These data suggest that the McDonald's new McVeggie burger represents a less harmful fast-food choice than the beef burger.
