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

OBJECTIVES: To investigate the use of armspan as a proxy for height in the assessment of nutritional status using body mass index (BMI) for four ethnic groups in Ethiopia. DESIGN: Cross-sectional study. SETTING: Four regions in Ethiopia, namely Oromia, Amhara, Tigre and Somali Region. SUBJECTS: A total of 1706 (884 males and 822 females) Ethiopians aged 18-50 y from four different ethnic groups. METHODS: Anthropometric measurements (weight, height and armspan) were obtained using standard techniques. BMI using height (BMI-ht) and using armspan (BMI-as) were calculated, t-tests were used to compare means, and linear regression to investigate the relationship between BMI-ht and BMI-as. RESULTS: Ethnic and sex differences in the relationship between height and armspan, and their derived variables (BMI-ht and BMI-as), were found. Armspan and height (r=0.83-0.9), and BMI-ht and BMI-as (r=0.89-0.97), were highly correlated in all ethnic groups. BMI-as cut-offs equivalent to the conventional BMI-ht classification of chronic energy deficiency were similar in the Oromo, Amhara and Tigre, but substantially higher in the Somalis. CONCLUSION: Armspan can be used as a proxy for height to estimate BMI, but the relationship between the two measures varies considerably with ethnicity and sex. Unless sex- and ethnicity-specific cut-offs are applied, the use of BMI-as using conventional cut-offs will overestimate the prevalence of underweight in these populations.

The Effect on Elderly Parents in Cambodia of Losing an Adult Child to AIDS

Little systematic quantitative research is available on the parents of adults who become ill and die of AIDS despite their large number and the wide range of adverse consequences. This study, based on survey data from Cambodia, explores economic and social effects on parents in a country characterized by extreme poverty and a substantial AIDS epidemic. Results indicate that parents play a major role during the illness of an adult son or daughter, often sharing living quarters, providing care, and paying for illness-related expenses. These contributions to the societal response to AIDS come at considerable cost to parents at advanced ages. Multivariate analysis suggests lasting negative consequences for parents'economic well-being, and the consequences are more substantial if the adult child's death was from AIDS rather than from other causes. The study found little evidence of stigma associated with losing a grown child to AIDS: reactions from local community members are more likely to be sympathetic and supportive than negative. These results underscore the need for organizations dealing with AIDS to recognize the contributions older persons make in coping with the epidemic and to address the burden it imposes on them.
