The effect of vitamin D levels on lipid, glucose profiles and depression in perimenopausal women.

Abstract

Vitamin D deficiency is a significant problem that affects the population living in most countries. This issue is independent by place of residence, sex, age or skin color. It is mainly influenced by the environment we live in and by an unhealthy lifestyle, including bad eating habits. The aim of this study was to evaluate lipid profile, glucose levels, and vitamin D levels, considering sociodemographic variables, smoking and alcohol consumption in perimenopausal women. Depressive mood was also assessed considering sociodemographic variables and vitamin D levels. The study was conducted on a group of 191 women and performed in two stages. The first of them was carried out using a diagnostic survey with the use of a technique questionnaire. The applied research instruments were the author's questionnaire (concerning sociodemographic and selected medical data), and the Beck Depression Inventory. The second stage of the study involved the collection of peripheral blood from each respondent, in order to determine lipid profile, glycemia and serum vitamin D levels. The age of the female respondents ranged from 45 to 65 years, mean age was 53.1 ± 5.37 years, median 53 years. Vitamin D levels were below normal in 78%; 77% had elevated total cholesterol levels; 91.6% of the respondents had high density lipoprotein (HDL) cholesterol levels within the normal range; 64.4% was characterized by too high (low-density lipoprotein) LDL cholesterol, and 84.8% of the women showed normal triglyceride levels. Among the respondents, 91.1% had normal glycemic levels. Analysis of the collected data showed a weak negative correlation between serum vitamin D levels and the levels of total cholesterol (rho=-0.14; p=0.05), LDL cholesterol (rho=-0.16; p=0.026), and triglycerides (rho=-0.22; p=0.002). Only in the case of HDL cholesterol (p=0.067), there was no statistically significant correlation. There were also no statistically significant correlations between serum vitamin D levels and glycemia or severity of depression. 1. The majority of the women did not manifest depressive disorders. Of all factors analyzed, only education was associated with the severity of depressiveness. 2. Smoking adversely affected serum vitamin D levels in the studied women. 3. The cessation of menstruation affected carbohydrate metabolism and vitamin D levels. Blood glucose levels increased with the age of the studied women. 4. Relationships were found between the levels of vitamin D and the levels of total cholesterol, LDL cholesterol, and triglycerides. Therefore, it is important to maintain normal vitamin D levels.
