Anthropometric characteristics of older people in rural Malawi

Abstract

Background: Older people are becoming an increasingly important proportion of the populations of developing countries, yet little information exists on their nutritional status or social conditions. Objective: To assess the nutritional status of older people in rural Malawi. Design: Cross-sectional study. Setting: Lilongwe, Malawi. Subjects: A total of 296 respondents (97 males and 199 females) aged from 55±94 y were studied. Methods: Selected anthropometric measurements were taken by trained personnel. Among kyphotic respondents, height was estimated from armspan using regression equations derived from the non-kyphotic respondents. Body mass index (BMI) and corrected arm muscle area (CAMA) were computed using standard equations. Results: The mean age of the respondents was 63.3 y and 68.9 y among females and males, respectively. Kyphosis was seen in 17.3% of all subjects and oedema in 4.1%. Nearly 90% of the subjects were involved in agricultural activities. Men were heavier and taller than women but women had larger MUACs and triceps skinfolds than males. The mean BMIs in kg/m 2 ( AE s.d.) were as follows: 19.7 (2.6) for men and 20.3 (3.0) for women. The prevalence of undernutrition, de®ned as BMI`18.5 kg/m 2 , was 36.1% among males and 27.0% among females. In contrast, using MUAC (cut-offs 23 cm for males and 22 cm for females), 20.4% of the men and only 10% of the women were classi®ed as malnourished. Conclusion: The study demonstrated for the ®rst time that undernutrition is a signi®cant problem among older people in rural Malawi. It highlights the need to incorporate older people into existing and future nutrition and health programmes.

Mini Nutritional Assessment of rural elderly people in Bangladesh: the impact of demographic, socio-economic and health factors

“…Using anthropometric measures, a study from rural Malawi demonstrates that undernutrition among its older people is a significant problem 24 . In central Uganda, the prevalence of malnutrition, based on BMI and mid upper-arm circumference, within the population aged 60-90 years is reported to be 33% and 52%, respectively 25 .…”

“…However, it is questionable whether the results, generated by international reference tables, are realistic. Correct interpretation of anthropometric measures is important because they are used to detect subjects or populations at risk for poor health and to design and follow up health interventions (Chilima & Ismail, 1998). In industrialised countries, reference tables are usually available and regularly updated (Freeman et al, 1995;Chinn et al, 1996;Fredriks et al, 2000;Cacciari et al, 2002;Ogden et al, 2002).…”

The use of armspan measurement to assess the nutritional status of adults in four Ethiopian ethnic groups

“…However, most of the studies that looked at the association between armspan and height have focused on Caucasian subjects, and large ethnic differences in the association have been noted (Reeves et al, 1996). Equations developed for determining height from armspan in African populations are few and often based on small samples (Chilima & Ismail, 1998). Furthermore, equations established in the Malawian and Rwandan studies (Chilima, 1998;Pieterse, 1999) may not be appropriate for other African ethnic groups.…”
