Nutritional status and eating habits of the institutionalised elderly in Turkey: a follow-up study.

BACKGROUND: As the elderly population increases in Turkey, so do the associated health and nutritional problems. The main purpose of the present study was to determine the nutritional status of elderly individuals who live in institutions. METHODS: A total of 102 elderly volunteers was recruited from seven residential homes of the Ministry of Family and Social Policies in Ankara. In the consecutive years of 2007, 2008 and 2009, dietary intake was assessed using a 24-h food recall. Nutritional status was screened using a questionnaire from the Mini-Nutritional Assessment, basic characteristics were determined and anthropometric measurements were assessed. RESULTS: The percentage of elderly participants who were malnourished or at risk for malnutrition increased by the completion of the follow-up (P < 0.05). It was found that energy, total protein, animal proteins, carbohydrates, niacin, vitamin C, vitamin E and zinc intake of men decreased significantly over the years studied (P < 0.05). A significant decrease occurred among women in animal protein, vitamin B1 , niacin and the percentage of energy from proteins (P < 0.05); however, an increase in energy from fat (P < 0.05) was determined. Within the years studied, the percentage of nutrients meeting the Turkish recommended daily allowances decreased from 2007 to 2009 both in men and women. During the years 2007 to 2009, the percentage of waist circumferences >102 cm for men was 46.4%, 45.6% and 48.1%, respectively, and the percentage of waist circumferences for women >88 cm was 75.6%, 75.6% and 81.8%, respectively. CONCLUSIONS: During the follow-up, significant nutritional changes were determined. To prevent malnutrition, periodical screening of nutritional status should be a priority and a standard policy for elderly people, especially for those institutionalised.

Plasma lipids in Turkish children: impact of puberty, socioeconomic status, and nutrition on plasma cholesterol and HDL.

In Turkish adults, HDL cholesterol (HDL-C) levels are 10-15 mg/dl lower than those of adults in western Europe and the United States. In this study, we determined whether HDL-C levels in Turks are low from birth to adulthood and assessed the effect of socioeconomic status (SES) on plasma lipids and lipoproteins. Analyses of cord blood from 105 Turkish newborns showed low levels of plasma cholesterol ( approximately 60 mg/dl) and HDL-C (approximately 30 mg/dl), consistent with results from other Western ethnic groups. Prepubescent 8- to 10-year-old Turkish boys and girls of upper (n = 82) and lower (n = 143) SES had high HDL-C levels (50-60 mg/dl) similar to those of western European children. However, the cholesterol (154-158 mg/dl) and HDL-C (55-58 mg/dl) levels of upper SES children were approximately 25 and approximately 12 mg/dl higher, respectively, than those of lower SES children. Height, weight, skinfold thickness, and estimated body fat were greater in the upper SES children and appeared to reflect dietary differences. Upper SES children consumed more total fat (approximately 35% vs. 25% of total calories), including more saturated fat of animal origin, and less carbohydrate (approximately 50% vs. 62% of total calories), consistent with their elevated plasma cholesterol levels. Carbohydrate intake correlated inversely with the HDL-C level. The HDL-C levels in the prepubescent children, especially those of higher SES, who consumed diets more like western Europeans, decreased markedly to adult levels, with males exhibiting a approximately 20 mg/dl decrease (from 58 to 37 mg/dl) and females a approximately 13 mg/dl decrease (from 55 to 42 mg/dl). SES did not affect HDL-C levels in adults. The profound decrease may reflect alterations in androgen/estrogen balance in Turks at puberty and a modulation of hepatic lipase affecting HDL-C levels.
