A nutritional study was carried out on 30 rural, low-income women, aged 25 to 35 years, in the village of Dhandra, Ludhiana District, Punjab, India, to measure the energy cost of selected household and farm activities. The mean weight, mid-upper-arm circumference, and triceps skinfold thickness were below the reference standards. A negative energy balance among the subjects indicated their poor energy status. The energy costs of selected household and farm activities were assessed by the Caltrac personal activity computer. The energy costs of household activities—making dough, making chapatis, grinding masala, hand pumping, washing utensils, sweeping, mopping, washing the floor, mud pasting, and washing clothes—were 0.0306. 0.0281, 0.0595, 0.0337, 0.0266, 0.0424, 0.0530, 0.0331, 0.0634, and 0.0453 kcal/kg/min, respectively. The energy costs of farm activities— collecting fodder, chaffing fodder, milking, making dung cakes, picking sag, harvesting wheat, bundling wheat, picking paddy, brooming paddy, and separating paddy—were 0.0472, 0.0372, 0.0530, 0.0270, 0.0337, 0.0623, 0.0374, 0.0411, 0.0370, and 0.0744 kcal/kg/min, respectively. All selected activities were categorized as light, except for grinding masala, mopping, mud pasting, harvesting wheat, separating paddy, and milking, which were categorized as moderate on the basis of Food and Agriculture Organization (FAO) physical activity ratios. The Caltrac gave lower values for the energy costs of most of the activities. Although it is simpler and less costly, the Caltrec must be calibrated against methods of measuring oxygen consumption for similar activities.
