[Control effect of health education on body mass index of community population].

OBJECTIVE: To examine the effect of community-based health education and health promotion on body mass index (BMI), overweight and obesity. METHODS: We separately selected 100,000 population in Beijing, Shanghai and Changsha Cities during 1991-2000. Each of the cities was then randomly separated intervention and control community of 500,000 population. In the intervention community various kinds of health education and health promotion had been carried out. The level of knowledge, attitude and behavior (KAB) and body mass index (BMI) were evaluated. RESULTS: The net increases of KAB level and regularly exercising rate in three city and different target population were statistically differences in comparison with baseline survey of 1992, and the net decreases of the BMI, overweight rate and obesity rate of the whole population were statistically differences. CONCLUSION: Health education and health promotion can effectively control the rising of population BMI, and have great meaningful for population preventing from cardio-cerebro-vascular diseases.

A statistical approach to schistosome population dynamics and estimation of the life-span of Schistosoma mansoni in man.

Dynamic models which predict changes in the intensity of schistosome infection with host age are fitted to pre-intervention Schistosoma mansoni data from Kenya. Age-specific post-treatment-reinfection data are used to estimate the force of infection, thus enabling investigation of the rate of worm death. An empirical and statistical approach is taken to the model fitting: where possible, distributional properties and function relationships are obtained from the data rather than assumed from theory. Attempts are made to remove known sources of bias. Maximum likelihood techniques, employed to allow for error in both the pre-intervention and reinfection data, yield confidence intervals for the worm life-span (CI95% = 5.7-10.5 years) and demonstrate that the worm death rate is unlikely to vary with host age. The possibilities and limitations of fitting dynamic models to data are discussed. We conclude that a detailed, quantitative approach will be necessary if progress is to be made with the interpretation of epidemiological data and the models intended to describe them.

Population categorization and cancer statistics.

Racial/ethnic groups as used in data published by the US government are defined by sociopolitical and not scientific criteria. Much can be learned through the study of cancer rates of various populations. This knowledge benefits all who are at risk for the disease. Cancer incidence and mortality rates are influenced by numerous extrinsic factors such as diet, socioeconomic status, and cultural factors that often correlate with race/ethnicity. The prevalence of a gene or genetic mutation is often higher in a particular population compared to another. While a specific gene or series of genes can be conserved within a relatively closed population, genetic variation within a given population or race is significant.
