Parental backgrounds of Otago medical students.

AIMS: To investigate the background of medical students admitted to the Otago Medical School (OMS) in terms of their parents' occupations, socioeconomic status and education, and to assess how this has been affected by the introduction of substantial tuition fees. METHODS: A questionnaire was used to collect data on the occupations and education of the parents of all successful New Zealand applicants to the OMS between 1987 and 2000. Trends in the data across the years were examined, and the data compared to the wider New Zealand population. Occupational data were also coded against the 1997 New Zealand Socioeconomic Index of Occupational Status. RESULTS: The distribution of data changed very little from 1987 to 2000. Of 2391 students surveyed, 2353 (98.4%) responded to the questionnaire. Of the respondents, 55.2% had at least one parent with a professional occupation at the time they entered the Medical School, 63.2% had at least one university-educated parent, and 13.1% of students had at least one parent who was a doctor. CONCLUSIONS: In comparison to the wider population, the students surveyed were much more likely to have highly educated, professional parents from higher socioeconomic groups. Although only about one in eight medical students came from medical families, this proportion was much higher than in the wider population. These characteristics changed very little across the 14 years of the study, despite substantial increases in university tuition fees.

[Nutritional status of children and occupational categories of the family in a rural community of Paraná, Brazil].

The relationship between the occupational category of the family and the nutritional status of children was studied. Participants were 340 children up to 11 years of age, living in a small town of a rural area in Paraná, Brazil. The nutritional status of the children, as measured in 1983, was related to the principal occupational categories of the family in the period 1972- 1983. Occupation of the family was categorized as: migrant farmworkers (bóias-frias) throughout the entire period; renters or sharecroppers that were converted to migrant farmworkers; those who never worked as migrant farmworkers; and salaried urban workers that were converted to migrant farmworkers. Other variables included age and sex of the children, condition of birth (home or hospital), number of children up to 11 years of age in the family, birthweight and school enrollment of the children 5 years old or over. The prevalence of wasting was greatest among children belonging to salaried urban workers that were converted to migrant farmworkers. In contrast, this category showed the lowest prevalence of stunting. Compared with migrant farmworkers during the entire period, the odds ratio of wasting in this category was 2.7 with a 95% confidence interval of 1.3-5.7. Wasting and stunting were also independently associated with the number of children (p<0.05). The larger the family, the lower the risk of wasting, whereas for stunting, the larger the family, the higher the risk. These findings suggest an important role for the occupational category in the determination of the nutritional status in children and indicate that wasting and stunting may have differential risk factors.

Validity and repeatability of self-reported occupational and industrial history from patients in EEC countries.

The results of a study to assess the feasibility and acceptability of a questionnaire designed to ascertain occupational history and the repeatability of coding occupational and industrial status using an abbreviated version of the coding status are presented for EEC countries. The study demonstrates the difficulty of recruiting cancer patients below age 65. The percentage of useful information among patients who completed a self-administered questionnaire was slightly lower than those who completed an administered questionnaire but in general the response rate for most items in the questionnaires in any group was above 90%. The repeatability of coding occupational status and industrial status for current or last job was satisfactory with Kappa values of 65% and 76% respectively. The within-individual repeatability for these variables had similar Kappa values. The validity of coding occupational status with an abbreviated version of coding status compared to the full instructions was satisfactory for current or last occupation. However, observer variability may be fairly large for the abbreviated version. An increase in the coding repeatability could probably be achieved with few modifications to the description of occupation status groups and clearer headings for each division of the Industrial Occupation Classification and greater training of coders.

Substitutability of work and the professionalization of occupational therapists.

This paper examines the status of occupational therapy as a profession. Achievement of status as a full-fledged profession will depend on the success with which this group convinces members of society that the work it does is non-substitutable. It is difficult for occupational therapists to prove there is no legal substitute for the services they offer. This factor will likely limit attainment of status as a full-fledged profession.

Validation of the theory: satisfaction with time-delimited daily occupations.

OBJECTIVES: This study examines the construct validity of the theory Satisfaction with time-delimited daily occupations (STO). The outcome of STO concerns how individuals perceive their occupational health status and to what degree the individuals experience satisfaction with their performance of time-delimited daily occupations. DESIGN: The "known-groups technique" was used for discriminating the occupational health status among four groups (n = 147) of full-time workers or sick-listed participants. A mailed ActivityLog-sheet was used for recording their occupational health 24 times during 24 hours. The computerized program ActivityLog was used for data registration. The data analysis were accounted by ANOVA, Tukey's HSD test with significance level of p < 0,05 using the SPSS program. RESULTS: The occupational health status did not differ significantly among the four groups, but the number of records concerning work (p = 0,00) and care (p = 0,02) time-delimited daily occupations were significantly different. The patterns of occupational health status during the 24-hour-records were visually separated for the four groups. CONCLUSION: There is need for refining the STO theory and then for undertaking further investigations of the STO construct validity.

Demographic predictors of self-reported loneliness in adults.

The relative magnitude of individual demographic characteristics, compared with other demographic characteristics, in the prediction or explanation of frequency of loneliness has not been examined or reported in the literature. The relative strengths of a series of demographic variables (gender, age, marital status, household income, educational attainment, race or ethnicity, employment status, and occupation) in explaining frequency of loneliness in a random sample of 8,634 adults residing in a large metropolitan county were examined. Logistic regression analysis indicated several variables significantly affected group membership as lonely vs not lonely: marital status, household income, gender, and educational attainment. The strongest predictor of all was marital status. Age group as a predictor variable approached significance, but employment status, occupational, and race/ethnicity were not significant predictors of group membership as lonely vs not lonely in the logistic regression model.

Decreased immune status in Nigerian workers occupationally exposed to lead.

Some immunological indices of 80 Nigerian lead workers were assessed. The mean blood lead level (BLL) in the study subjects was significantly higher than in control non-exposed subjects (p < 0.001). The mean values for total globulins and C-reactive protein (CRP) were also significantly raised in the test subjects. (P < 0.001, P < 0.01 respectively). In contrast, levels of IgA and IgT were significantly depressed (P < 0.01, P, 0.001 respectively). Furthermore, a significant negative correlation was established between IgA and BLL (r = 0.28 P < 0.009). Ascorbate excretion was also significantly reduced in the exposed workers when compared with control subjects. (P < 0.02) Multiple regression analysis established significant interaction between BLL and total globulin and IgA I(P < 0.01, P < 0.01, 0.28 and P < 0.009 respectively). Principal component analysis showed that CRP, TLC, IgA and IgC have strong interactions with BLL. These data suggest depressed immune status in workers occupationally exposed to lead. This clinical state may be modulated by genetic and nutritional factors (such as ascorbate level). The control population was made up of 50 volunteers who had never been exposed to lead. Their mean age was 36.6 (semi 1.2 range 22-58) years. Informed consent was obtained from all 130 subjects and the ethical committee of the college of Medicine Ibadan, approved the conduct of the study. Additionally, it may predispose the subjects to increased susceptibility to infectious diseases, inflammatory disorders and cancer.

Education and other measures of socioeconomic status and risk of incident Alzheimer disease in a defined population of older persons.

OBJECTIVE: To assess the relations of 3 measures of socioeconomic status (education, occupational prestige, and income) to risk of incident clinically diagnosed Alzheimer disease (AD). DESIGN: Cohort study with an average observation of 4.3 years. SETTING: East Boston, Mass. a geographically defined community. PARTICIPANTS: A stratified random sample of 642 community residents 65 years of age and older who were free of AD at baseline. MAIN OUTCOME MEASURE: Clinical diagnosis of probable AD according to standard criteria, using structured uniform evaluation. RESULTS: The relations of the 3 measures of socioeconomic status to risk of disease were assessed using logistic regression analyses. In individual analyses, fewer years of formal schooling, lower income, and lower occupational status each predicted risk of incident AD; risk of disease decreased by approximately 17% for each year of education. In an analysis including all 3 measures, the effect of education on risk for disease remained approximately the same, but the effects of the other 2 measures were somewhat less and did not attain formal statistical significance, compared with separate analysis of each measure. CONCLUSIONS: Markers of lower socioeconomic status predict risk of developing incident AD. The mechanism of this relation is uncertain, but the possibility that it reflects unidentified and potentially reversible risk factors for the disease deserves careful investigation.

Health status assessment in the occupational health setting.

This article discusses the conceptual roots of measuring health- related outcomes based on a biopsychosocial model of health. The selection and applicability of instruments for measurement of health status are discussed and suggestions are made concerning how health-status instruments may be used in the occupational- health setting. The potential value of measuring health status in the occupation-health setting is explored with a brief review of current literature and an example from one investigation in which measurements of health status were used to examine outcomes of common musculoskeletal impairments.

Patterns of tobacco use in the early epidemic stages: Malawi and Zambia, 2000-2002.

OBJECTIVES: I examined demographic and socioeconomic patterns of tobacco use in 2 African nations in the early stages of epidemic. METHODS: I used population-based data from the Demographic Health Surveys of men aged 15-59 years (N=5111) and women aged 15-49 years (N=20809) in Malawi (2000) and Zambia (2001/2002) and multinomial logistic regression models to examine tobacco use (nonsmoker, light cigarette smoker, heavy cigarette smoker, and user of other tobacco) as a function of age, residence, education, occupation, marital status, and religion. RESULTS: Male tobacco users tend to be less educated, urban, household service or manual workers, formerly married, and non-Christian and non-Muslim. Although tobacco use is less common among women, it relates inversely to their education and occupational status. Tobacco users more often reported drinking, getting drunk, and, among men, paying for sex. CONCLUSIONS: Tobacco use patterns in 2 African nations at the early stages of epidemic suggest the need for public health officials to focus on disadvantaged groups to prevent the worldwide spread of tobacco.

Adverse work and environmental conditions predict occupational injuries. The Israeli Cardiovascular Occupational Risk Factors Determination in Israel (CORDIS) Study.

This study was designed to test whether the total objective adverse work and environmental conditions, expressed as the ergonomic stress level (ESL), would predict occupational injuries over a 2-year period. The study population consisted of 4,096 men from 21 factories in six industrial sectors who were studied as part of the Israeli Cardiovascular Occupational Risk Factors Determination in Israel (CORDIS) Study, 1985-1987. The ESL (assigned four levels, 1-4) was based on an ergonomic assessment which covered 17 risk factors pertaining to safety hazards, overcrowding, cognitive and physical demands, and environmental stressors. The ESL was found to be a highly reliable measure and stable over a period of 2-4 years. The incidence of injuries among workers in low ESL conditions (level 1) was 10.3%. It increased with higher ESL's: 11.7% in level 2 (relative risk (RR) = 1.13, 95% confidence interval (CI) 0.86-1.50); 21.6% in level 3 (RR = 2.09, 95% CI 1.68-2.62); and 23.8% in level 4 (RR = 2.31, 95% CI 1.85-2.88). After adjustment for age, job experience, educational level, managerial status, and occupational status (white/blue collar), injury occurrence was significantly elevated for those at level 3 (adjusted odds ratio (OR) = 1.46, 95% CI 1.12-1.91) and level 4 (adjusted OR = 1.81, 95% CI 1.39-2.37) but not for level 2 (adjusted OR = 0.87, 95% CI 0.65-1.18). The authors conclude that adverse work and environmental conditions, objectively assessed, can predict occurrence of occupational injuries.

Dimensions of occupations: genetic and environmental influences.

This study investigates the dimensions of occupation, and distances between occupational categories, by using intra-pair differences in adult occupational position for identical twins reared apart. Status and farm dimensions of occupation were identified. The results validate the use of occupational status as a dimension of occupational position. The causes of individual differences for the derived status dimension were also evaluated, based on groups of identical and fraternal twins reared apart or together. Genetic effects accounted for a substantial amount of the variance in occupational status for men, while shared and non-shared environmental effects were of about equal importance. For women, genetic effects were less important, and shared and non-shared environmental effects accounted for more of the variation. The results confirm that genetic effects are important sources of the familial resemblance often found for occupational status for men.

Predictors of career commitment and employment level of tertiary-educated Indonesian women.

This study investigated the relationships among education, liberal sex-role values, gender-role orientation (masculinity/femininity), career commitment, and employment level for a sample of 302 married Indonesian women. All participants were tertiary educated and currently employed either as teachers in tertiary institutions or as managers in government or private enterprise. Multiple regression analysis revealed that liberal sex-role values and masculinity were significant predictors of career commitment, whereas education was the only variable to significantly predict employment level. Results are compared with previous research on predictors of career commitment and employment level in both Asian and Western cultures. Directions for further research are discussed.

Sero-epidemiological study of hepatitis B virus infection in a village.

A cross-sectional study was conducted in a randomly selected village of Rangpur district from June '94 to May '95. Serum from 1000 human subjects irrespective of age and sex were screened for hepatitis B surface antigen (HBsAg). Among the respondents 661 were male and 339 female. The overall seroprevalence of HBsAg was 6.4%. It was 6.66% in male and 5.89% in female. Age, sex, religion, income, occupation, education and marital status did not show any relationship with HBsAg status. Among 64 sero-positive cases, 16 (25%) had no history of exposure to known risk factors and 48 (75%) had one or more exposure to known risk factors (p < 0.05). This study did not depict the national scenario. Well designed studies with more sensitive serological methods are recommended to get the epidemiological information of hepatitis B virus (HBV) infection in our community.

Effect of occupation on lipid peroxidation and antioxidants' status in masons.

Effect of occupation on haematological factors, lipid peroxidation and antioxidants' status was studied in masons and compared with normal subjects. Red blood corpuscles (RBC), haemoglobin (Hb), Vitamin C, Vitamin E, beta-carotene levels and glutathione peroxidase (GSHPx), superoxide dismutase (SOD) and catalase (CAT) activities decreased. Thiobarbituric acid reacting substances (TBARS) level increased. Occupational exposure to cement increased lipid peroxidation but decreased antioxidants' levels in masons. Increased lipid peroxidation seems to be responsible for the reduction in RBC and Hb.
