“…Most of the respondents classi®ed as undernourished (undernutrition de®ned as BMI1 8.5 kg/m 2 ) were actually mildly undernourished. Height not only declines with age (Dequeker et al, 1969;van Leer et al, 1992;de Groot et al, 1996;Parker et al, 1996), but is also dif®cult to measure accurately since many old people have problems standing upright and most walk with a slight bend at the hip and knees (Atchley, 1985). Thus ordinary BMI may underestimate the true prevalence of undernutrition in an elderly population.…”

“…Individuals with a low BMI may encounter problems in responding to emergencies. Some studies have reported a decline in BMI with advancing age (Yassin & Terry, 1991;Parker et al, 1996;Strickland & Ulijaszek, 1993), while others have indicated otherwise (Carmelli et al, 1991). In this study, mean BMI was slightly lower in the oldest men and women.…”

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.

The 6-Minute Walk Test in Chronic Respiratory Failure: Does Observed or Predicted Walk Distance Better Reflect Patient Functional Status?

BACKGROUND: Acquiring 6-min walk test (6MWT) data from patients undergoing noninvasive mechanical ventilation due to chronic hypercapnic respiratory failure is limited. We aimed to assess whether the actual 6-min walk distance (6MWD) or the percent predicted 6MWD is a better reflection of the respiratory function of patients using home noninvasive ventilation (NIV) due to chronic hypercapnic respiratory failure. METHODS: This was a cross-sectional observational study. The 6MWT was performed in subjects using home NIV. Diagnoses were grouped as COPD, obesity hypoventilation syndrome (OHS), kyphoscoliosis, and parenchymal lung disease. Sex, age, and body mass index (BMI) were used to calculate ideal 6MWD. The correlation of percentof-predicted 6MWD with spirometry and arterial blood gas values were better than with the actual 6MWD. CONCLUSIONS: The percent-of-predicted 6MWD was better correlated with respiratory function than actual 6MWD for subjects using home NIV due to chronic hypercapnic respiratory failure with COPD, OHS, kyphoscoliosis, and parenchymal lung disease.

Does body height reduction influence interpretation of lung function in COPD patients?

Vertebral deformities are prevalent in chronic obstructive pulmonary disease (COPD) patients and may cause excessive loss of height. As height is used for calculating reference values for pulmonary function tests, larger than normal height reduction could cause overestimation of lung function.In this cross-sectional study of 465 COPD patients and 462 controls, we explored how often lung function is misinterpreted due to height reduction in COPD patients, and whether the number or severity of vertebral deformities correlate with height reduction.Measured height was compared to recalled tallest height (RTH) and height calculated from arm span (ASH) to assess height reduction. Vertebral deformities were assessed from radiographs and pulmonary function was assessed using standard formulae.Height reduction was frequent in both the study and control groups, and increased with the number and severity of vertebral deformities. When using current measured height, lung function was overestimated in a significant proportion of COPD patients at relatively modest height reductions. The effects were smallest for forced expiratory volume in 1 s and forced vital capacity, and most pronounced for total lung capacity and residual volume. Therefore, we propose that in COPD patients with excessive height reduction, one might use RTH or ASH in calculating predicted values. Furthermore, such patients should be evaluated for co-existing vertebral deformities and osteoporosis.
