Sociodemographic patterns in spina bifida birth prevalence trends--North Carolina, 1995-1999.

Previous studies have documented a decline in neural tube defects (NTDs) in the United States after the addition of folic acid to enriched grain products and other folic acid initiatives. The decrease generally has been greater for spina bifida than for other NTDs. However, the extent to which the decline varies by maternal sociodemographic characteristics has not been examined. In this study data from the North Carolina Birth Defects Monitoring Program, a statewide, population-based birth defect surveillance program, were used to assess the impact that folic acid public health initiatives have had on spina bifida rates among various sociodemographic subpopulations in North Carolina. This report covers data from 1995 through 1999. The overall prevalence of spina bifida decreased by 27.2% during 1995-1996 and 1998-1999 (p = 0.014). The magnitude of the decline varied considerably by sociodemographic characteristics of the mother. The decline was greatest among mothers who were aged > or = 30 years (prevalence ratio [PR] = 0.53), who had more than a high school education (PR = 0.57), whose prenatal care was not paid by Medicaid (PR = 0.67), and who were non-Hispanic white (PR = 0.72). Geographically the decrease in the western and Piedmont regions of the state was almost threefold that occurring in the eastern region. The decline in spina bifida after fortification varied considerably by sociodemographic subpopulations. More effort is needed to target folic acid education programs at disadvantaged populations.

Tobacco use among high school students--United States, 1990.

Tobacco use is the single most preventable cause of death in the United States. Approximately half of smokers start smoking regularly before 18 years of age; however, among recent birth cohorts, age of smoking initiation has declined, especially among females. Data on tobacco use among adolescents help identify high-risk populations, design tobacco-prevention programs for these populations, and evaluate the effectiveness of broad efforts to prevent tobacco use among youth. This report examines the prevalence of self-reported current tobacco use and frequent cigarette smoking among U.S. students in grades 9-12 during 1990.

Cancer among indigenous populations. The experience of American Samoans.

BACKGROUND: Little is known about the cancer control needs of American Samoans. This report provides some of the first data on cancer incidence among American Samoans in Hawaii. METHODS: The Hawaii Tumor Registry, a Surveillance, Epidemiology, and End Results population-based, active cancer surveillance program, provided archival data on American Samoans residing in Hawaii and on those referred to Hawaii for diagnosis and treatment from the U.S. Territory of American Samoa. RESULTS: In American Samoan males, the more commonly encountered cancers included cancer of the lung, prostate, stomach and liver, and leukemia. In American Samoans females, breast carcinoma was most frequent, followed by cancer of the corpus uteri, cervix uteri and thyroid, and leukemia. Females were more likely than males to receive a diagnosis of cancer at an early age: 34.5% of females and 19.9% of males with cancer were diagnosed when they were between the ages of 0 and 44 years. Males were more likely than females to be diagnosed with cancer after metastasis had occurred (45% vs. 33.9%). Compared with other Polynesians (i.e., Western Samoans and Hawaiians), American Samoan males have a relatively higher frequency of lung, prostate, thyroid, and liver cancers and a lower frequency of colon and rectum cancers. American Samoan females, compared with other Polynesians, have a higher frequency of leukemia and corpus uteri, thyroid, and pancreatic cancers and a lower frequency of colon and rectum cancers. CONCLUSIONS: The data provide baseline information that has important public health and research implications for cancer control programs for this population.

Increase in skin cancer screening during a community-based randomized intervention trial.

Survival from cutaneous melanoma is mainly dependent on the thickness of the lesion at diagnosis. Skin screening may increase detection of thin lesions and hence improve survival. Within a community-based randomized controlled trial of a population screening program for melanoma in Queensland, Australia, 9 communities were randomly assigned to the 3-year intervention and 9 communities to the control group. Skin screening prevalence was monitored by cross-sectional surveys at baseline, 1, 2 and 3 years into the intervention and 2 years later. At baseline, prevalence of whole-body clinical skin examination was similar in intervention and control communities. In intervention communities, the prevalence of whole-body skin examinations increased to 29.2%, an absolute difference of 18% from baseline, with a peak of 34.8% 2 years after baseline, and began to decline again at the end of the intervention period. The largest increases were seen in men and women > or =50 years. Uptake of screening did not differ according to melanoma risk factors; however, the decline in screening was less in participants who reported a number of melanoma risk factors. The prevalence of skin self-examination remained stable during the intervention program. No changes were observed in the control communities. These results indicate that the intervention program significantly increased the prevalence of whole-body clinical skin examinations in intervention communities. Once the intervention program ceased, and particularly after skin clinics ceased, levels of skin screening began to decline. The provision of specialized skin screening clinics may be needed to achieve sufficient screening rates should population based screening for skin cancer be considered.

China. Population. New threat.

Although China's population growth rate in 1980 was the lowest in 31 years, doubling of marriages and increasing life expectancy have emerged as threats to the government plan to hold national population growth to 1200 million by the end of the present century, a Beijing official magazine reported. Liaowang (Observation), published by the government's Xinhua news agency, quoted state family planning officials as saying that a subsequent doubling of marriages this year "threatens another baby boom in the world's most populous nation." The officials said the country's population stood at 982.55 million at the end of 1980, roughly equivalent to 20% of the world's total. According to the magazine, the natural population growth rate declined to 8.97 million last year as the number of births fell to 14.99 million and that of deaths stood at 6.02 million. During the past decade, the natural increase rate of China's population dropped from 26/1000 in 1970 to just 12/1000 in 1980. Owing to increase in production and living standards, along with expansion and improvement of medical facilities, the mortality rate fell from almost 30/1000 before the founding of the People's Republic of China to around 6-8/1000 by the 1970s. According to U.N. statistics prepared for the recently-held international conference on population and development in Beijing, China succeeded in reducing its birth rate by as much as 23.1% between 1960-65 and 1970-75. But such accomplishment is now in danger of being wiped out by a new birth peak expected during the next 10 or more years as those born during the baby boom of the 1960s reached childbearing age during the present decade. In addition, the population control program is also threatened by the rising life expectancy of the Chinese people. Latest statistics compiled by the Ministry of Public Health showed that the average life span of the Chinese population had doubled to 68 years in 1980 from 35 years in 1949.

Association of waist circumference with risk of hypertension and type 2 diabetes in Nigerians, Jamaicans, and African-Americans.

OBJECTIVE: Prior studies have supported that waist circumference correlates better with visceral adipose tissue and is a better predictor of cardiovascular disease than are BMI and waist-to-hip ratio. In this study, we reexamine the role of waist size on the risk of hypertension and type 2 diabetes in African-origin populations from three contrasting environments. RESEARCH DESIGN AND METHODS: A cross-sectional survey was conducted of 5,042 men and women 25-74 years of age from Nigeria, Jamaica, and the U.S. The relationship between waist, blood pressure, and fasting blood glucose was assessed using multiple linear regression analyses. Logistic regression analyses using sex-specific empirical waist cut-points were used to determine the risks of hypertension and type 2 diabetes. RESULTS: Waist circumference was positively correlated with blood pressure and fasting blood glucose (P < 0.05). Increasing waist quartiles were significantly associated with higher risks of hypertension in the three populations, as estimated from age-adjusted odds ratios obtained from sex-specific logistic regression models. A highly elevated risk of type 2 diabetes-10-fold for Jamaican men and 23-fold for African-American women-was observed in the comparison of lowest to highest quartiles of waist circumference. CONCLUSIONS: Substantial reduction in hypertension and diabetes in men and women is achievable if the waist size is decreased in these populations. Intervention programs designed to reduce waist circumference through lifestyle modification, including exercise and diet, may have significant public health significance in reducing the incidence of hypertension and adult-onset diabetes in these populations.

The impact of initiating a human immunodeficiency virus screening program in an urban obstetric population.

OBJECTIVE: Our purpose was to describe the incidence of human immunodeficiency virus infection and to assess the cost/benefit ratio of universal antenatal human immunodeficiency virus screening. STUDY DESIGN: Medical records of women in this urban obstetrics population, from the years 1988 to 1993, were examined. The incidence of known human immunodeficiency virus seropositivity at delivery was determined. The costs of performing human immunodeficiency virus screening, evaluating the disease status, and administering therapy were calculated. These costs were compared with an averaged cost for care and follow-up of infants infected through vertical transmission. RESULTS: The incidence of known human immunodeficiency virus seropositivity at delivery approximately doubled since the initiation of a human immunodeficiency virus screening program (0.26% to 0.48%). Obstetric screening added an approximate $100,000 to medical costs. The calculated cost of pediatric follow-up of human immunodeficiency virus-seropositive infants for the first 18 months was estimated at $344,355. In our population, with universal screening and zidovudine therapy, the medical costs could be reduced by $175,500 per year. CONCLUSION: A program of voluntary human immunodeficiency virus screening increases the incidence of known human immunodeficiency virus infection. Offering screening and follow-up to all pregnant patients in an urban setting is both cost-effective and medically beneficial.

A comparison of population versus individual based cardiovascular disease prevention programs in Västerbotten, Sweden.

The purpose of this paper is to determine if differences in health outcomes of two cardiovascular disease prevention programs can be attributed to the inclusion of population based efforts in one of the programs. Propensity score matching has been used to eliminate possible selection bias. The results indicate that the intervention including population-based measures was not more effective than the intervention directed toward the individual.

Genetic screening and ethics: European perspectives.

Analysis and comparison of genetic screening programs shows that the extent of development of programs varies widely across Europe. Regional variations are due not only to genetic disease patterns but also reflect the novelty of genetic services. In most countries, the focus for genetic screening programs has been pregnant women and newborn children. Newborn children are screened only for disorders which are treatable. Prenatal screening when provided is for conditions for which termination may be offered. The only population screening programs for adults are those for thalassaemia carrier status in Cyprus, Greece and Italy. Social responses to genetic screening range from acceptance to hostility. There is a fundamental tension between individual and community in the debates in various European countries about implementation of screening programs. Opposition to genetic screening is frequently expressed in terms of arguments about "eugenics" with insufficient regard to the meaning of the term and its implications. Only a few countries have introduced explicit legislation on genetic screening. Legislation to address discrimination may provide more safeguards than legislation protecting genetic information itself.

Autopsy recruitment program for African Americans.

A specialized brain autopsy recruitment program was implemented within the context of advance medical directives and end-of-life treatment decisions. The program was implemented within the framework of a larger study. The purpose of the program was to (1) improve the rate of consent for brain autopsy among African Americans diagnosed with stroke and dementia, and (2) obtain more empirical information on the underlying reasons for the low response rate (4%) in this minority group. A convenience sample of 133 patient and family caregiver pairs was selected for participation. Face-to-face, open-ended interviews were conducted to ascertain reasons for autopsy preferences and to identify respondents interested in the postmortem procedure. Preferences for brain autopsy were ascertained and individuals interested in the procedure were subsequently followed through death or over the 2 1/2 year course of the study. Brain necropsies were conducted on patients requesting the examination. Thirty-six (36) patient and family pairs consented to the procedure, 16 were indecisive and 81 refused. Factors influencing decisions included existing attitudes toward autopsy, family agreement regarding the procedure, and assurance that funeral arrangements would not be delayed. Ninety deaths and two autopsies were conducted before implementation of the specialized recruitment program, yielding a 2.22% completion rate, and 34 deaths with 10 postmortems conducted within the time frame of the recruitment study, yielding a 29% autopsy completion rate. Fisher exact test (p < 0.0001) revealed a significant difference in the proportion of autopsies completed before and after implementation of the specialized recruitment program. Findings strongly suggest that culturally sensitive recruitment programs may increase the rate of autopsy request made by African American caregivers for relatives diagnosed with dementia and stroke. To obtain a higher rate of consent than that obtained in the general population, the program must contain ethnically sensitive recruitment strategies.
