“…In domestic study, obesity women have been associated with higher health risk due to lower variability of food intake than normal weight women. [26] In this study, we could not find the cause of lack of vitamin C and vitamin D intake in obesity group because food intake was not investigated concurrently. Because calcium and vitamin D are very important for skeletal health, it is necessary to emphasize intake of calcium- and vitamin D-containing food that can satisfy it; furthermore, awareness for increasing antioxidant nutrient intake is necessary.…”

Background: In the life cycle, bone mineral density (BMD) is the most optimal condition in the 20s. In Korea, vitamin D deficiency status is very serious in Korean women due to recent lack of activity, weight polarization, and inadequate nutritional intake. The purpose of this study was to compare serum vitamin D and BMD according to obesity status in Korean young adult women. Methods: A total of 143 female college students participated in the research. Body fat and lean body status were analyzed using a body composition analyzer. Nutrient intakes of the subjects were assessed by 3-days food record method. The BMDs was measured by dual energy X-ray absorptiometry. The subjects were divided into normal weight group and obesity group on their body mass index. Results: Obesity group showed significantly higher weight, body fat (%), and body fat (kg) than normal weight group and T-scores of lumbar-2 spines were significantly lower. Obesity group showed high triglyceride and low-density lipoprotein cholesterol levels and vitamin D levels were significantly lower. Physical fitness and activity status showed that sit and reach and sit up were significantly lower in obesity group. The intake of carbohydrates was higher in the obesity group than in the normal weight group, and the intake of vitamin C and vitamin D was significantly lower. Factors affecting serum vitamin D were analyzed as body fat (%), lumbar-2 T-score, triglyceride, and carbohydrate intake. Conclusions: Obese women need more effort to manage their serum vitamin D status and balanced nutrition to prevent bone loss.

“…A multivariable logistic regression analysis was used to calculate the odds ratio (OR) and 95% confidence intervals (CIs). Based on a preliminary analysis and literature review, potential confounding factors and effect modifiers were considered in the study analysis [16,[21][22][23][24][25]. We found no significant effect modifier for the association between obesity and vitamin D status.…”

Obesity and Vitamin D Insufficiency among Adolescent Girls and Young Adult Women from Korea

2019

Although there is evidence of the biological mechanisms by which obesity may induce vitamin D insufficiency or deficiency, limited epidemiological studies have been conducted, especially among Asian adolescent girls and young adult women who are at a high risk of vitamin D deficiency. This study aimed to examine the cross-sectional association between obesity and vitamin D insufficiency among adolescent girls and young adult women in Korea. We used data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2008-2014, and 3623 girls and young adult women aged 12-29 years were included. Demographic and lifestyle data were collected using a self-administered questionnaire from the health interview survey. Serum 25-hydroxyvitamin D (25(OH)D) level, body mass index (BMI), and body fat percentage (BF%) were measured during health examinations. Multivariable logistic regression was used considering the complex, multistage probability sample design of KNHANES. In the multivariable-adjusted analyses, obese girls and women, defined by BMI, were more likely to have a higher prevalence of vitamin D insufficiency (odds ratio [OR]: 1.49, 95% confidence interval [CI]: 1.03-2.17). This association was also evident for BF%. Participants with ≥30% BF% had a significantly higher prevalence of vitamin D insufficiency (OR: 1.52, 95% CI: 1.07-2.16). Obesity may worsen vitamin D insufficiency among adolescents and young women because of the fat-soluble characteristics of vitamin D and related health behaviors, such as a lack of outdoor activity. Further large-scale prospective cohort studies or randomized controlled trials are warranted to confirm this causality.
