| Résumé : | [BDSP. Notice produite par INIST-CNRS nIGeR0x9. Diffusion soumise à autorisation]. Background : This study evaluated whether food insecurity and obesity were associated in a population sample in Trinidad. Methods : A sample was drawn of 15 clusters of households, in north central Trinidad. Resident adults were enumerated. A questionnaire was administered including the short form Household Food Security Scale (HFSS). Heights and weights were measured. Analyses were adjusted for age, sex, and ethnic group. Results : Data were analysed for 531/631 (84%) of eligible respondents including 241 men and 290 women with a mean age of 47 (range 24-89) years. Overall, 134 (25%) of subjects were classified as food insecure. Food insecurity was associated with lower household incomes and physical disability. Food insecure subjects were less likely to eat fruit (food insecure 40%, food secure 55% ; adjusted odds ratio [OR]=0.60,95% CI : 0.36-0.99, P=0.045) or green vegetables or salads (food insecure 28%, food secure 51% ; adjusted OR=0.46,95% CI : 0.27-0.79, P=0.005) on>=5-6 days per week. Body mass index (BMI) was available for 467 (74%) subjects of whom 41 (9%) had BMI<20 kg/m2,157 (34%) had BMI 25-29 kg/m2, and 120 (26%) had BMI>=30 kg/m2. Underweight (OR=3.21,95% CI : 1.17-8.81) was associated with food insecurity, but obesity was not (OR=1.08,95% CI : 0.55-2.12). Conclusions : Food insecurity was frequent at all levels of BMI and was associated with lower consumption of fruit and vegetables. Food insecurity was associated with underweight but not with present obesity. |
