Association of vitamin D insufficiency and low physical activity with fatigue, headaches and psychological distress in college students, North-Mediterranean Croatia – a pilot study

Background: Poor vitamin D status is a worldwide health problem. Yet, knowledge about vitamin D status among adolescents in Southern Europe is limited. This study investigated concentrations and modulating factors of vitamin D in a healthy population of male late adolescents living in Southern Switzerland. Methods: All apparently healthy subjects attending for the medical evaluation before the compulsory military service in Southern Switzerland during 2014-2016 were eligible. Dark-skin subjects, subjects on vitamin D supplementation or managed with diseases or drugs involved in vitamin D metabolism were excluded. Anthropometric measurements (body height, weight, fat percentage, mid-upper arm and waist circumference) and blood sampling for total 25-hydroxy-vitamin D, total cholesterol and ferritin concentrations testing, were collected. Participants filled in a structured questionnaire addressing their lifestyle. Characteristics of the subjects with adequate (≥50 nmol/L–≤250 nmol/L) and insufficient (<50 nmol/L) vitamin D values were compared by Kruskal-Wallis test or χ2 test. Odds ratios for 25-hydroxy-vitamin D insufficiency were calculated by univariate and AIC-selected multiple logistic regression models. Results: A total of 1045 subjects volunteered to participate in the study. Insufficient concentrations of vitamin D were detected in 184 (17%). The season of measurement was the most significant factor associated with vitamin D levels and approximately 40% of subjects presented insufficient vitamin D concentrations in winter. After model selection, body fat percentage, frequency and site of recreational physical activity, and the seasonality were significantly associated with the risk of vitamin D insufficiency. Conclusions: Among healthy male late adolescents in Southern Switzerland, about one every fourth subject presents a poor vitamin D status in non-summer seasons. Body fat percentage, frequent and outdoor recreational physical activity are modulating factors of vitamin D status in this population.

Abstract Background: Vitamin D deficiency is a major public health problem in China while there are seldom reports about vitamin D nutrition status in Chinese college students. The purpose of this study is to explore the vitamin D status of the college freshmen who came from different provinces of China and to comprehensive analyze the effects of diet, physical activity, and UV protection on serum vitamin D levels. Methods: Totally 1,667 freshmen who came from 26 provinces, autonomous districts or municipalities, were recruited into this study. An online questionnaire was used to collect the information including demographic status, diet habit, physical activity, and UV protection of the participants. Serum 25(OH)D3 concentrations were measured using a liquid chromatograph mass spectrometer. Multivariate linear regression analyses were used to explore the comprehensive influence of diet, physical activity, and UV protection on serum 25(OH)D3 levels. Results: The average age of the subjects was18.55±0.90 years, with 23.0% male and 77.0% female. The mean serum 25(OH)D3 was 18.06±6.34ng/mL and the proportion of vitamin D deficiency and insufficiency was 67.5% and 27.8%, respectively. Multivariate linear regression indicated that milk and yogurt intake≥200mL/d, calcium or vitamin D supplements and average time of outdoor activity ≥60 min/day were positively linked to higher serum vitamin D while sweets intake ≥10g/d and higher UV protection index were negatively influenced serum vitamin D after adjusted for age, gender, students’ original residence, latitudes and longitude. Conclusions: Vitamin D deficiency is an important health problem in Chinese college students. Milk and yogurt intake and outdoor activity should be encouraged while sweets intake should be limited for preventing vitamin D deficiency. Public health policies should consider well-balanced guidelines on UV protection and vitamin D food fortification or supplementation.

Vitamin D insufficiency, a risk factor for osteoporosis, has been well investigated in elderly women worldwide, but little information has been available for younger women. This study aimed to determine serum 25-hydroxyvitamin D [25(OH)D] levels in Japanese female college students, and to test whether there is an association between 25(OH)D and bone strength. Subjects were 77 Japanese female junior college students aged 19–24 years. Serum 25(OH)D was measured with high performance liquid chromatography. Bone strength of the calcaneus was evaluated using the osteo sono-assessment index (OSI), a combined index reflecting the bone mass, bone architecture, and elasticity, as measured by quantitative ultrasound densitometry (AOS-100, Aloka). The mean 25(OH)D concentration was 34.2 nmol/L (SD ± 12.1). The proportion of subjects with 25(OH)D less than 30 nmol/L, a cut-off value for vitamin D insufficiency, was 31/77 (40.3%). Simple linear regression analysis showed that there was a significant linear relationship between 25(OH)D and OSI (R2 = 0.098, p = 0.0069). The association held even after adjusting for weight (partial R2 = 0.098, p = 0.0023). Body weight was also a significant predictor of OSI (partial R2 = 0.105, p = 0.0034). These results suggest that vitamin D insufficiency may be prevalent in healthy young women. Moreover, low levels of 25(OH)D in young women may adversely affect bone strength. An additional, newly designed epidemiological study with a sufficient sample size is needed to confirm the present findings.

The purpose of this pilot study was to examine students' use of the campus recreation center and their engagement with the center's social media accounts as a basis for future research. A survey was completed by 257 students in an undergraduate health course. The respondents were 38% female and 61% male, and 29% freshmen, 44% sophomores, 18% juniors, and 7% seniors. Results indicated that while the majority of students use Facebook and Twitter, most of them do not follow the center's accounts. However, students who participated in the least popular activities at the center were more likely to follow and interact with the center's social media. Potentially, students do not want to connect with the recreation center on social media and managers should shift resources to a different marketing strategy, or managers need to engage in a campaign to increase students' awareness of the center's accounts.

AbstractIt has been suggested that alterations in inflammation molecules maintain chronic pain although little is known about how these factors influence homeostatic and inflammatory events in common chronic pain conditions. Nonpharmacological interventions might be associated with alterations in inflammation markers in blood. This study of patients with chronic pain investigates whether an interdisciplinary multimodal rehabilitation program (IMMRP) was associated with significant alterations in the plasma pattern of 68 cytokines/chemokines 1 year after rehabilitation and whether such changes were associated with clinical changes. Blood samples and self-reports of pain, psychological distress, and physical activity of 25 complex chronic pain patients were collected pre-IMMRP and at 12-month follow-up. Analyses of inflammatory proteins (cytokines/chemokines/growth factors) were performed directly in plasma using the multiplex immunoassay technology Meso Scale Discovery. This explorative pilot study found that 12 substances, mainly pro-inflammatory, decreased after IMMRP. In two other relatively small IMMRP studies, four of these proinflammatory markers were also associated with decreases. The pattern of cytokines/chemokines pre-IMMRP was associated with changes in psychological distress but not with pain or physical activity. The present study cannot impute cause and effect. These results together with the results of the two previous IMMRP studies suggest that there is a need for larger and more strictly controlled studies of IMMRP with respect to inflammatory markers in blood. Such studies need to consider responders/non-responders, additional therapies, involved pain mechanisms and diagnoses. This and the two other studies open up for developing biologically measurable outcomes from plasma. Such biomarkers will be an important tool for further development of IMMRP and possibly other treatments for patients w ith chronic pain.

Vitamin D Levels

Background: Vitamin D deficiency is frequently seen nowadays due to inadequate exposure to sun and pollution. The present study was undertaken to evaluate the prevalence of vitamin D deficiency in patients presenting with suggestive complaints.Methods: The present study is a retrospective study done at Srinivas Institute of Medical Sciences and Research Centre, Mukka, Suratkal, Mangaluru. Patients who have musculoskeletal or other problem suggestive of vitamin D deficiency were advised vitamin D levels. We went through OPD papers of only those patients with reports of Vitamin D levels.Results: In present study, out of 100 patients, 42 (42%) patients had normal BMI, 23 (23%) patients were overweight, 24 (24%) patients were obese while 11 (11%) patients were underweight. 46 (46%) patients were having walk for exercise purpose, 21 (21%) were doing work out at gym while 33 (33%) patients were walking only for doing some work. 47 (47%) patients had normal levels of vitamin D, 31 (31%) had insufficient levels while 22 (22%) patients had deficient levels of vitamin D. So, prevalence of vitamin D deficiency was 22% and for vitamin D insufficiency was 31%.Conclusions: In present study, we conclude that irrespective of normal body mass index or physical activity, patients presented with various complaints. In them, vitamin D levels were either insufficient or deficient in large number of patients. So, vitamin D levels should be done as screening or at least when patients present with suggestive complaint.
