BackgroundSince 1996, arterial hypertension has been recognized as one of the main health priorities in Martinique. However, its prevalence in the general population has never been measured. Furthermore, obesity is increasing in many countries and studies have shown that hypertension is more frequent in obese people than in people with normal body mass index. The objective of this survey is to measure hypertension prevalence in the general population and to study the link between hypertension, weight status and socioeconomic level.MethodsCross-sectional study of randomly selected homes in randomly selected geographical islets. All household members in these homes constituted the eligible population. Arterial hypertension was defined as systolic pressure greater than 140mmHg and/or diastolic pressure greater than 90mmHg and/or antihypertensive treatment. Weight status was estimated using the body mass index.ResultsStudy concerned 1504 persons aged 16 years or older with a sex-ratio of 0.7 and an average age of 48.3 years for men and 48.5 years for women, p=0.88. The prevalence rate of hypertension is 29% [IC(95%): 25.9-31.8] in the sample and declines to 22.5% [IC(95%): 20.1-25.1] using weighted data. The prevalence rate is 33.1% [IC(95%): 30.2-36.6] for overweight and 20.1% [IC(95%): 17.8-22.6] for obesity. Being overweight is more frequent among persons with hypertension than among ones with normal blood pressure, 73.0 versus 47.4%; p<0.001. In those with hypertension, overweight does not differ significantly between men and women, but the prevalence of obesity is greater among women than among men (35.7 versus 20.6 %, p<0.05).ConclusionThe high prevalence of both hypertension and obesity in the general Martinican population has been confirmed by this study. Prevention actions are required to decrease the cardiovascular risk in this population.
