Waist circumference as a measurement of obesity in the Netherlands Antilles; associations with hypertension and diabetes mellitus.

OBJECTIVES: To evaluate waist circumference (WC) as a screening tool for obesity in a Caribbean population. To identify risk groups with a high prevalence of (central) obesity in a Caribbean population, and to evaluate associations between (central) obesity and self-reported hypertension and diabetes mellitus. DESIGN: Cross-sectional. SETTING: Population-based study. SUBJECTS: A random sample of adults (18 y or older) was selected from the Population Registries of three islands of the Netherlands Antilles. Response was over 80%. Complete data were available for 2025 subjects. INTERVENTION: A questionnaire and measurements of weight, height, waist and hip. MAIN OUTCOME MEASUREMENT: Central obesity indicator (WC > or =102 cm men, > or =88 cm women). RESULTS: WC was positively associated with age (65-74 y vs 18-24 y) in men (OR=7.7, 95% CI 3.4-17.4) and women (OR=6.4, 95% CI 3.2-12.7). Women with a low education had a higher prevalence of central obesity than women with a high education (OR=0.5, 95% CI 0.3-0.7). However, men with a high income had a higher prevalence of a central obesity than men with a low income (OR=1.7, 95% CI=1.1-2.6). WC was the strongest independent obesity indicator associated with self-reported hypertension (OR=1.7, 95% CI 1.4-2.0) and diabetes mellitus (OR=1.6, 95% CI 1.3-1.9). CONCLUSIONS: The identified risk groups were women aged 55-74 y, women with a low educational level and men with a high income. WC appears to be the major obesity indicator associated with hypertension and diabetes mellitus.

The Saba health study: methodology and main results

'The Saba Health Study' is the first large scale health interview survey of the island. This book presents the main results of the study. It discusses the population's health status, use of health services, and satisfaction with health care. Known health risks, such as smoking, alcohol consumption, and overweight are evaluated and compared with situations on the sister island of Curacao and in western countries. Attention is focused on the identification of risk groups in need of specific policy interventions and health promotion programs (AU)

Lifestyle in Curaçao. Smoking, alcohol consumption, eating habits and exercise.

The Curaçao Health Study was carried out among a randomized sample (n = 2248, response rate = 85%) of the adult non-institutionalized population in order to assess aspects of lifestyle that may pose health risks. Factors examined were tobacco and alcohol use, eating habits and exercise behaviour. Outcome variables were cross-tabulated by gender, age and socioeconomic status. 17.1% of the participants were smokers and 20.5% were regular drinkers, including 6.3% of the men who consumed alcohol excessively (4 or more glasses of alcohol a day). 75% of the participants did not exercise regularly, 37% did not eat vegetables daily, and half did not eat fruit daily. Other poor eating habits were the addition of extra sugar and salt to prepared food by 33% and 20% of the participants, respectively. On the whole, men had less healthy lifestyles than women, with the exception of exercise behaviour. People of high socioeconomic status (SES) drank less alcohol, and exercised more often than those of low SES. Considering the high prevalence of diabetes mellitus and hypertension in the Caribbean, research on lifestyle factors in other Caribbean countries is required to facilitate the development of regional prevention and intervention programmes.
