“…Our study found a positive association between low vitamin D status (25(OH)D ≤ 30 ng/mL) and PBF, which is also concordant with the literature [17,25,34,44]. While this relationship is not fully understood, it is assumed that since vitamin D is a fat soluble vitamin, it might be sequestered in the excess adipose tissue of obese adults and would be slowly released at negative energy balance [17]. Further, a potential confounder is that obesity is also linked to an unhealthy lifestyle, characterized by less physical activity, less sun exposure and, hence, lower vitamin D concentrations [45].…”

“…The association of adiposity, measured by WC and PBF, with serum 25(OH)D is usually stronger than that with BMI [43]. In concordance with our results, multiple studies showed that vitamin D concentrations were significantly lower in both males and females with high risk WC compared to low risk categories (p < 0.05) [9,11,17].…”

“…affecting the relationship between vitamin D status and percentage body fat (PBF) were not assessed thoroughly. Further, the association between obesity and vitamin D status could also differ between gender and among different ethnic groups [15][16][17]. There is a substantial body of evidence supporting a genetic basis for low 25(OH)D concentrations in the Middle East.…”

Vitamin D status and body composition: a cross-sectional study among employees at a private university in Lebanon

Background: The prevalence of low vitamin D status is increasing globally, and Lebanon is not spared. The objectives of this study are to determine the prevalence and correlates of low vitamin D status, and to assess the association between percent body fat and vitamin D status, independently of obesity. Methods: A cross-sectional study was performed on NDU employees. Data on dietary intake, physical activity, lifestyle, health status, and demographic variables were collected during a face-to-face interview. Anthropometric measures (weight, height and waist circumference) were measured and body composition was assessed using the bioelectrical impedance analysis (BIA) machine InBody 720 (Biospace, Seoul, Korea). The Nutritionist Pro diet analysis software version 31.0 was used to estimate dietary intake of vitamin D. Serum 25 hydroxyvitamin D (25(OH)D) was measured using enzyme linked immunosorbent assay kit (ELISA) (Calbiotech, Spring Valley, California, USA). Vitamin D status was assessed according to the National Osteoporosis Foundation (sufficiency: ≥ 75 nmol/L / ≥30 ng/mL) and the Institute of Medicine cut-offs (adequacy: ≥50 nmol/L / ≥20 ng/mL). Statistical analyses were performed by SPSS version 22. Results: A total of 344 employees (50% Male) aged between 20 and 74 years participated in the study. More than half of the participants were overweight and obese. Mean serum vitamin D concentrations were 28.2 ± 13.9 ng/mL. Among participants, 37.5% of our study population had 25(OH)D ≥ 30 ng/mL, and 68.3% had 25(OH)D ≥ 20 ng/mL. Individuals with low vitamin D status had significantly higher percent body fat (PBF) (p < 0.005), and higher waist circumference (WC) (p = 0.012) than in the sufficient group, however BMI did not differ by vitamin D status. Logistic regression analysis indicated that a 1% increase in body fat increases the odds of having 25(OH)D ≤ 30 ng/mL by 8% while controlling for BMI and other confounders (p = 0.019). Conclusion: This study reinforces the need for regular screening for low vitamin D status in Lebanese adults, particularly individuals at risk, including those with high risk WC, high PBF, who work indoors and have low vitamin D intake, and recommending vitamin D supplementation if needed.

“…Yet, intermediate biomarker of obesity demonstrated an inverse relationship between adiposity and low vitamin D levels. 32 However, as highlighted by Ibero-Baraibar et al, 33 no causal relationship has been proved. Note also that, this relationship could be also altered by the volumetric dilution and sequestration of vitamin D in adipose tissue.…”

Obesity and severe obesity constitute growing serious health problems reaching epidemic proportion in most countries with a prevalence increasing from 6.4 in 1975 to 14.9% in 2014. This present review summarizes currently available data on vitamin D deficiencies in the obese population before and after bariatric surgery. The important evidence emerging from our evaluation confirms that obese patients are at risk of multiple nutritional deficiencies, especially vitamin D deficiency, before bariatric surgery. Our survey confirms that the precise role of the gut microbiome and its associated changes on the vitamin D metabolism after the different bariatric surgery procedures has not yet been studied. Furthermore, whether differences in the microbiota may alter the therapeutic responses to vitamin D is not known. AbstractObesity and severe obesity constitute growing serious health problems reaching epidemic proportion in most countries. Interactions and relationships between obesity and bone tissue and its metabolism are complex but are more and more studied and recognized. Obesity is associated with an altered hormonal profile including particularly bone-regulating hormones like vitamin D. Bariatric surgery procedures, thanks to their effectiveness to achieve therapeutic endpoints for comorbidities associated with obesity, have had an increasing success. However, these surgeries by producing mechanical restriction and or malabsorption syndrome lead to nutritional deficiencies including vitamin D. In this review, we aim to (1) discuss the nutritional deficiency of vitamin D in the obese, (2) to summarize the different surgical options in bariatric surgery and to present the evidence concerning these procedures and their associated profile in vitamin D post-operative insufficiency, (3) to present the different recommendations in clinical practice to prevent or treat vitamin D deficiencies or insufficiencies in patients treated by bariatric surgery and finally to introduce emerging assumptions on the relationship between vitamin D, microbiota composition and circulating bile acids.

“…Body mass index is negatively associated with vitamin D status [31,32,33,34,35] and vitamin D inadequacy is highly prevalent among children who are overweight or obese compared to non-overweight children [1]. Obese children may have elevated vitamin D requirements due to the sequestration of lipid-soluble vitamin D in a larger pool of adipose tissues [6,35,36], lower vitamin D metabolism in the liver [36], increased vitamin D catabolism in the kidneys [6,36], or limited sun exposure due to low physical activity levels [36].…”

Parental Encouragement of Healthy Lifestyles for Their Children and Personally Caring about Healthy Lifestyles Is Positively Associated with Children Using Vitamin D Supplements

et al. 2016

Supplement users have better vitamin D status, and parenting is key to promoting a child’s healthy behaviours. We examined the association of parental encouragement of and caring about healthy lifestyles with children’s use of vitamin D supplements and multivitamins. A provincially representative sample of grade 5 students (n = 2686; 10–11 years) and their parents across the province of Alberta, Canada, was surveyed in 2014. Students were asked about use of multivitamins and/or vitamin D supplements. Parents were asked whether they cared about and encouraged healthy lifestyles. Mixed effect multiple logistic regression identified the association of parental responses with children’s use of supplements; 29% and 54% of children took vitamin D supplements and multivitamins, respectively. They were more likely to take vitamin D supplements if their parents cared ‘very much’ vs. ‘not at all/a little bit’ about eating healthy foods (OR = 1.43; 95% CI = 1.08, 1.89), cared ‘quite a lot’ (OR = 1.55; 95% CI = 1.17, 2.04) and ‘very much’ (OR = 1.67; 95% CI = 1.26, 2.21) vs. ‘not at all/a little bit’ about physical activity, and encouraged ‘very much’ vs. ‘not at all/a little bit’ their children to eat healthy foods (OR = 1.51; 95% CI = 1.05, 2.17). Children whose parents personally cared for eating healthy foods were more likely to take multivitamins (‘quite a lot’ and ‘very much’ compared to ‘not at all/a little bit’ (OR = 1.60; 95% CI = 1.13, 2.28 and OR = 1.46; 95% CI = 1.04, 2.06, respectively). Education and parental encouragement of healthy lifestyles should be part of the public health initiatives to promote supplementation of vitamin D among children.
