Seasonal Difference of Nutrient Intake, Serum Lipid and Antioxidative Index in Female College Students: Young Sook Ko, Hong Seok Ahn; Korean J Community Nutr 2007;12(2):142-149. Published online April 30, 2007

Abstract PDF: To evaluate the seasonal differences of nutrient intake and serum biochemical indices (total cholesterol, HDL-, LDLcholesterol, TG, MDA:malondialdehyde, TAS : total antioxidant status, folate) in Korean college women with a mean age of 20.15y, this study was conducted twice: once in winter and a second time in summer. Anthropometric assessment was also measured in the two seasons. As a result, body fat mass (p < 0.05), body fat% (p < 0.05), and abdominal fat% (p < 0.01) in the summer were significantly lower than those in winter. Intake of fat (p < 0.05), polyunsaturated fatty acid (p < 0.01), zinc (p < 0.05), and vitamin E (p < 0.05) were at significantly higher levels in the summer period compared with the winter period. In addition, nutrients with an intake level less than 75% RI of KDRIs were folate in winter and calcium, and folate in the summer. Total cholesterol (p < 0.05) and HDL-cholesterol in summer, according to lipid profiles, were significantly lower than those in winter. Although MDA, one of the products of lipid peroxidation, remained unchanged, TAS was significantly higher in summer than in winter. The level of folate in summer showed significantly lower than that in winter. The present study suggests that nutrient intake of college women women differs according to the seasons and anthropometric indices and serum biochemical indexes were associated with seasons. Thus nutritional education programs on the basis of season are needed for college women.

A Study on the Food Habit and Seasonal Difference of Nutrient Intake of Adult Working Women: Hwa Jae Lim; Korean J Community Nutr 2005;10(4):501-512. Published online August 31, 2005

Abstract PDF: To assess the food habits and the seasonal differnces of nutrient intakes and diet qualities of adult working women aged 30 - 49y in Busan, dietary survey was conducted in summer and in winter by a questionnaire and two-day food record. Anthropometric assessment was also investigated in two seasons. 91.8% of those skipped breakfast in the main. 44.3% had irregular meals. The mean daily energy intake was 1725.8 kcal with 63.3% of energy intake being supplied by carbohydrates, 14.7% by protein, 22.3% by fat in summer and 1598.4 kcal with 62.1% of energy intake being supplied by carbohydrates, 15.6% by protein, 22.1% by fat in winter. Over 70% of iron intake came from plant origin in two seasons. The mean intakes of energy, calcium, iron and vitamin A in summer and energy, calcium, iron, vitamin A and vitamin B2 in winter were below Recommended Dietary Allowance (RDA) for Koreans. As well as insufficiency in iron, the bioavailability of iron is considered to have been low because most of iron intake came from plant origin in two seasons. For calcium and iron in summer and calcium, iron, vitamin A and vitamin B2 in winter, proportions of subjects with intake levels less than 75% of RDA were over 40% in summer and over 50% in winter, respectively. The nutrient adequacy ratios (NAR) were below 0.75 for calcium and iron in summer and calcium, iron, vitamin A and vitamin B2 in winter. NARs of iron (p < 0.05), vitamin A (p < 0.01) and vitamin B2 (p < 0.001) in winter were significantly lower than those in summer. The mean adequacy ratios (MAR), an index of overall dietary quality were 0.85 in summer and 0.80 in winter. The MAR in winter was significantly lower than that in summer (p < 0.05). The indexes of nutritional quality (INQ) were below 1 for calcium and iron in summer and calcium, iron, vitamin A and vitamin B2 in winter. The intake (p < 0.05) and NAR (p < 0.05) of vitamin B2 showed positive significant correlations with height in winter. In conclusion, nutrient intake and diet quality of adult working women were different between the summer and the winter. So nutritional education programs for summer and winter are needed for adult working women.
