Perbandingan Perhitungan Energi Basal dan Energy Expenditure pada Lansia (The Comparison Of Estimation Of Basal Metabolic Rate And Energy Expenditure Of Elderly People)

摘要

Backgrounds: The determination of basal energy rate (BMR) is the primary step for estimating the energy requirement of an individual. For the population there is some equation to estimate basal energy rate based on the measurement obtain in the foeld such as body weight. Thus the publication was to compare between Schofield and oxford equation using the weight data of Riskesdas 2007. Method: A total of 41087 elderly people (20671 men and 20416 women) were including in this analysis with normal nutritional status (BMI 18.5 – 25.0 kg/m2). Data analysis were age, gender, body weight, height, and physical activities. Two equation were chosen for estimating BMR, the schofield equation that is recommended by FAO/WHO/UNU and Oxford equation that used in estimating BMR in Indonesia. Results: The average of basal metabolic rate of male elderly according to Schofield equation was 1217 ± 76.9 Kcal and Oxford equation was 1283 ± 108.6 Kcal, while basal metabolic rate of women elderly was 1090 ± 55.5 Kcal and Oxford was 1101 ±74.3 Kcal. The average of energy expenditure of male elderly according to Schofield equation was 1887 ± 119 Kcal and Oxford equation was 1283 ± 108.6 Kcal, while energy expenditure of women elderly was 1581 ± 81 Kcal and Oxford was 1598 ± 108 Kcal. Conclusion: The average of basal metabolic rate and energy expenditure among elderly people based on Oxford equation were higher compare to Schofield equation. [Penel Gizi Makan 2011, 34(1): 12-20]
