Anthropometry - Anthropometric measurements were taken by the researcher in the respondents‟ homes. Weight, height, waist and hip circumference and measures of body composition were recorded. Height was measured to the nearest 0.1cm using the Leicester portable height measure (Chasmores Ltd, UK) with the respondent's head positioned in the Frankfurt Plane. Waist circumference was measured in duplicate using a non-stretch tape measure and taken at the naked site where possible. Waist circumference was measured at the midpoint to the nearest 0.1cm between the iliac crest (top of hip) and the bottom of the rib cage (10th rib). Hip circumference was measured in duplicate to the nearest 0.1cm using a non-stretch tape measure. This measurement was taken over light clothing at the widest part of the buttocks at the level of the greater trochanter (bony prominence of the thigh bone). Weight and body composition were measured in duplicate using a Tanita body composition analyzer BC-420MA (Tanita Ltd, GB) to the nearest 0.1kg. Respondents were weighed after having voided, wearing light clothing and without shoes. Defining overweight and obesity in adults Body Mass Index (BMI) was used to indirectly assess adiposity and was calculated as weight (kg) divided by height squared (m2). The World Health Organisation (WHO) BMI cut-off points were used to estimate levels of underweight (<18.5kg/m2), normal weight (18.5-24.9kg/m2), overweight (25.0-29.9kg/m2) and obese (≥30 kg/m2).
