Rate and Risk of all cause mortality among people with known hypertension in a rural community of southern Kerala, India: The results from the prolife cohort
Background: Hypertension is one of the most important determinants of death due to vascular damage and is fast emerging as a high burden disease in India. However, its documentation is poor in the country. This study aims to estimate the rate and the causal pattern of mortality in a cohort of people with high blood pressure as compared to normotensives.
Methods: The study setting is Varkkala, a rural village in southern Kerala, India, and the study design was that of a prospective cohort. A total of 77,881 participants of age 20 years and above were considered for analysis. The rate and risk of all cause mortality (death due to any cause) among hypertensives were quantified and compared against the normotensives. The causes of death were also analyzedin both the groups. Cox proportional hazard models were created to estimate the hazard ratios of death among hypertensives adjusted for sociodemographic factors, behaviors, and comorbidities.
Results: The incidence proportion of deaths in the study was 4.28% during the follow-up period of 6 years. The relative risk of mortality was 3.13 (CI: 2.91-3.37) in the high BP group. The age-adjusted hazard ratio of all cause mortality for the high BP group was 2.96 (2.56-3.42). Coronary artery disease was the major cause of death among the subjects with high BP.
Conclusions: The study revealed high prevalence of hypertension in the study population. A person with hypertension is at three times higher risk of death due to any cause compared to a normotensive individual even after adjustment for age
Prevalence of undernutrition among tribal preschool children in Wayanad district of Kerala
Background: Nutritional status especially that of preschool children is a sensitive indicator of health and nutritional status of a community. Aim: To estimate the prevalence of undernutrition among tribal preschool children and to assess the factors associated with variation in nutritional status. Methods: A cross-sectional survey was conducted among 438 tribal preschool children in 10 clusters of Wayanad district of Kerala. Height, weight, mid-arm circumference and hemoglobin level were measured. Children more than two standard deviations (SDs) below the standard median of World Health Organization Multi Centric Growth Reference Study were considered underweight (weight-for-age), stunted (height-for-age) and wasted (weight-for-height) respectively. Qualitative variables such as prevalence of underweight, stunting and wasting were summarized using percentages. Mean (SD) was used, to summarize, quantitative variables such as height and weight. Generalized estimating equation models were constructed to assess associations. Adjusted models included social factors and child morbidities. Results: More than half of the children say 58.7% (257/438) had deficits in at least one of the three anthropometric indicators. The prevalence of underweight, stunting and wasting was 39% (171/438), 38% (167/438) and 20.5% (90/438) respectively. The prevalence of anemia was 95.7% (419/438). Bivariate analysis showed significant associations between undernutrition and educational status of parents, tribe to which the child belonged, diarrheal episode and low birth weight. In adjusted analysis, lower educational status of mother (adjusted odds ratio 1.9, 95% confidence intervals 1.2-3) and an episode of diarrhea (1.8, 1.03-3.2) independently predicted undernutrition in a tribal preschool child. Conclusion: Undernutrition in the form of stunting, wasting and underweight is very high among the tribal preschool children. There is an urgent need to improve health care services to the tribal population and tribal children
