Lk. Ethangatta et al., PROTEIN-ENERGY MALNUTRITION IN LOW-INCOME ELDERLY NAIROBI WOMEN, International journal of food sciences and nutrition, 47(2), 1996, pp. 147-157
Nutritional data for two groups of low income elderly women ((X) over
bar = 64, range 57-74 years) in Nairobi, Kenya were compared. Group I
(n = 113), slum dwellers, had an income of less than or equal to$20 Cd
per month; Group II (n = 88), poor urban area inhabitants, had an inc
ome of less than or equal to$170 Cd per month. Dietary intakes were as
sessed quantitatively by four 24-h dietary recalls; anthropometric and
biochemical data were obtained. Twenty-one women (16% of Group I; 3%
of Group II) were classified as having protein-energy malnutrition (PE
M) based on abnormal anthropometric measurements or low serum albumin
concentration. The malnutrition was marasmic-like; the anthropometric
measurements (body weight, triceps skinfold thickness (TSF), mid-arm m
uscle circumference (MAMC)) of the PEM Group were lower (P less than o
r equal to 0.05) than those of Groups I and II. The PEM Group was olde
r ((X) over bar = 68 years), had lost more teeth, and had more subnorm
al values than Groups I and II for: serum albumin, hemoglobin, hematoc
rit, MCHC, MCH, serum transferrin and serum iron. Inferior diets were
a contributing factor. Mean energy and protein intakes of the PEM Grou
p were low: 1471 kcal day(-1) (26 kcal kg(-1)) and 42 g day(-1) (0.79
g kg(-1)), respectively. The main protein sources were vegetables (48%
) and cereals (36%); only 6 g protein was of high quality. Group TI me
an protein and energy intakes were greater (P less than or equal to 0.
05, P less than or equal to 0.01) than those of the PEM Group and mean
dairy product intake was higher (P less than or equal to 0.001). The
PEM Group and Group I had low mean energy intakes and an unsatisfactor
y dietary pattern; they consumed less meat (P less than or equal to 0.
01) and less fat (P less than or equal to 0.001) than Group II. For th
e PEM Group dietary intakes of energy, fat and sugar were significantl
y correlated with TSF and MAMC; for the PEM Group monthly income was s
ignificantly correlated with weight, BMI, TSF and MAMC. Data suggest t
hat elderly women living in Nairobi slums are at high risk of malnutri
tion; one of the factors contributing to the problem is inadequate foo
d intake.
