Nutritional status and associated factors among community-dwelling elderly
Résumé
Background and aims: Although the ageing of the Cameroonian population is a public health issue in the coming years, the nutritional status of the elderly is unknown. The aim of the study was to assess the nutritional status, health status and associated socio-demographic factors among elderly in Cameroon.Methods: A cross-sectional study of 599 elderly (aged 60) was conducted in urban and rural areas. Several socio-demographic, sanitary, and anthropometric (weight, height, body mass index (BMI), Waist Circumference (WC), Mid-Upper Arm Circumference (MUAC)) data were collected. Nutritional status was defined according to WHO. Multinomial analysis was performed to identify factors associated with nutritional status. The threshold of statistical significance was 5%.Results: The population, representative of the elderly, was aged 68.9 ± 7.2 years, with sex ratio M/F ¼ 0.93, weight 68.5 ± 14.7 kg, BMI 24.7 ± 5.3,WC 90.1 ± 12.8 cm and MUAC 28.2 ± 5.0 cm. According to BMI, undernutrition was 19.7%, normal status 37.9%, overweight 24.9%, obesity 17.5%. The concordance for undernutrition between BMI and MUAC was weak (kappa ¼ 0.3). In multinomial analysis, only no medication was negatively associated with undernutrition (OR ¼ 0.3). Obesity was positively associated with the urban environment (OR ¼ 4.8) and inactivity (OR ¼ 2.9) and negatively associated with male gender (OR ¼ 0.4), widowed (OR ¼ 0.2), head of household (OR ¼ 0.4), no income (OR ¼ 0.3), one pathology(OR ¼ 0.4), no medication (OR ¼ 0.2), having normal diastolic pressure (OR ¼ 0.2).Conclusions: Undernutrition and obesity (more frequent in women, and in urban area) affect 37.2% of the elderly. These nutritional disorders are a public health problem that cannot be ignored.
