Association between Serum Vitamin D and Metabolic Syndrome in a Sample of Adults in Lebanon. Nutrients 2023; 15:nu15051129. [PMID: 36904128 PMCID: PMC10004784 DOI: 10.3390/nu15051129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 02/19/2023] [Accepted: 02/22/2023] [Indexed: 02/25/2023] Open
Abstract
The evidence on the association between vitamin D and metabolic syndrome (MetS) is inconclusive. This was a cross-sectional study to explore the relationship between vitamin D serum levels and MetS in a sample of Lebanese adults (n = 230), free of diseases that affect vitamin D metabolism, recruited from an urban large university and neighboring community. MetS was diagnosed according to the International Diabetes Federation criteria. A logistic regression analysis was performed taking MetS as the dependent variable, and vitamin D was forced into the model as an independent variable. The covariates included sociodemographic, dietary, and lifestyle variables. The mean (SD) serum vitamin D was 17.53 (12.40) ng/mL, and the prevalence of MetS was 44.3%. Serum vitamin D was not associated with MetS (OR = 0.99 (95% CI: 0.96, 1.02), p < 0.757), whereas the male sex, compared with the female sex and older age, was associated with higher odds of having MetS (OR = 5.92 (95% CI: 2.44, 14.33), p < 0.001 and OR = 1.08 (95% CI: 1.04, 1.11), p < 0.001, respectively). This result adds to the controversy in this field. Future interventional studies are warranted to better understand the relationship between vitamin D and MetS and metabolic abnormalities.

Factors Showing the Growing Relation Between Vitamin D, Metabolic Syndrome, and Obesity in the Adult Population: A Systematic Review. Cureus 2022; 14:e27335. [PMID: 36043008 PMCID: PMC9411819 DOI: 10.7759/cureus.27335] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Accepted: 07/27/2022] [Indexed: 02/07/2023] Open
Abstract
Several theories suggest an inverse association between increasing adiposity, particularly abdominal fat, and low vitamin D levels. As a result, several routes are likely to impact how vitamin D, obesity, and metabolic syndrome (MetS) interact. This systematic study followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. A comprehensive PubMed, PubMed Central, Google Scholar, and ScienceDirect database search was conducted for published papers over the previous five years. Studies were identified using the following criteria 1) participants, interventions, and outcomes (PIO) components, 2) free full text, 3) studies published in English, and 4) human studies, including systematic and narrative reviews and cross-sectional, observational studies, were among the inclusion and exclusion criteria. In total, 151 articles were returned, and 16 duplicates were rejected. After verifying the titles and abstracts of these records using the review's PIO components and eligibility criteria, 17 received a 70% or above score. On review of the literature, the release of adiponectin from fatty tissues was inversely correlated with body weight and BMI suggesting a link between vitamin D deficiency and insulin resistance.

Non-attitudinal and non-knowledge based factors constrain households from translating good nutritional knowledge and attitude to achieve the WHO recommended minimum intake level for fruits and vegetables in a developing country setting: evidence from Gulu district, Uganda. BMC Nutr 2021; 7:68. [PMID: 34749820 PMCID: PMC8576922 DOI: 10.1186/s40795-021-00469-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Accepted: 09/24/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The high level of incidence of mortality attributed to non-communicable diseases such as cancer, diabetes and hypertension being experienced in developing countries requires concerted effort on investment in strategies that can reduce the risks of development of such diseases. Fruits and vegetables (FV) contain natural bioactive compounds, and if consumed at or above 400 g per day (RDMIL) as recommended by World Health Organization (WHO) is believed to contribute to reduced risk of development of such diseases. The objective of this study was to determine in a developing country set-up, the extent to which rural and urban households conform to RDMIL, the status of nutritional attitude (NA) and knowledge (NK) associated with consumption of FV, and to delineate non-attitudinal and non-knowledge-based factors (NANK) that hinder achievement of RDMIL. METHOD A cross-sectional survey of 400 randomly selected households and 16 focus group discussions (FGD) were conducted using Gulu district of Uganda as a microcosm for a developing country setting. Level of consumption of FV was assessed using 24-h dietary recall and compared to RDMIL as a fraction (%). The status of NK and NA were determined using sets of closed-ended questions anchored on a three-point Likert scale. Further quantitative statistical analyses were conducted using t-test, chi-square, Pearson's correlation and multiple linear regression. FGD provided data on NANK factors and were analysed using qualitative content analysis procedure. RESULTS Urban and rural inhabitants met up to 72.0 and 62.4% of the RMDIL, respectively, with absolute intake being higher among urban than rural households by 37.54 g. NK and NA were good but the intensity of NK was higher among urban respondents by 11%. RDMIL was positively correlated with NA while socio-demographic predictors of RDMIL varied with household location. FGD revealed that primary agricultural production constraints, market limitations, postharvest management limitations, health concerns, social discomfort and environmental policy restrictions were the major NANK factors that hindered achievement of the RDMIL. CONCLUSIONS These results indicate that NANK factors constrain households from translating good NA and NK to achieve the RMDIL.

Meta-Analysis and Systematic Review of Micro- and Macro-Nutrient Intakes and Trajectories of Macro-Nutrient Supply in the Eastern Mediterranean Region. Nutrients 2021; 13:nu13051515. [PMID: 33946351 PMCID: PMC8145171 DOI: 10.3390/nu13051515] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 04/11/2021] [Accepted: 04/26/2021] [Indexed: 12/30/2022] Open
Abstract
The Eastern Mediterranean Region (EMR) is experiencing a nutrition transition, characterized by the emergence of overnutrition and micro-nutrient deficiencies. No previous study has comparatively examined nutrient intake in adults across countries in the EMR. This review examined the adequacy of nutrients in adults living in the EMR. Moreover, it analyzed the food balance sheets (FBS) for 1961–2018 to identify the trajectory of energy supply from macro-nutrients in the EMR. A systematic search was conducted from January 2012 to September 2020. Only observational studies were retained with a random sampling design. An assessment of the methodological quality was conducted. Levels of nutrient daily intake and their adequacy compared to the daily reference intake of the Institute of Medicine were reported across the region. No studies were identified for half of the region’s countries. Although nutrient energy intake was satisfactory overall, fat and carbohydrate intake were high. Intake of vitamin D, calcium, potassium, zinc, and magnesium were below that recommended. The analysis of the FBS data allowed for the identification of four linear patterns of trajectories, with countries in the EMR best fitting the ‘high-energy-supply from carbohydrate’ group. This systematic review warrants multi-sectorial commitment to optimize nutrient intake.

Gender Differences in the Pattern of Socio-Demographics Relevant to Metabolic Syndrome Among Kenyan Adults with Central Obesity at a Mission Hospital in Nairobi, Kenya. High Blood Press Cardiovasc Prev 2020; 27:61-82. [PMID: 31981085 DOI: 10.1007/s40292-020-00360-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2019] [Accepted: 01/07/2020] [Indexed: 12/28/2022] Open
Abstract
INTRODUCTION Metabolic syndrome (MetS) is a risk factor for cardiovascular-related morbidity and mortality. Although the risk factors for MetS are well documented, differences in gender-based demographics among Kenyan adults with central obesity are lacking. AIM Determine gender differences in the pattern of socio-demographics relevant to metabolic syndrome among Kenyan adults with central obesity at a mission hospital, Nairobi. METHODS A cross-sectional baseline survey involving adults (N = 404) with central obesity aged 18-64 years, as part of a community-based lifestyle intervention study. Respondents were systematically sampled using the International Diabetes Federation definition for MetS. Lifestyle characteristics, anthropometric, clinical and biochemical markers were measured and analyzed using SPSS. RESULTS High (87.2%) MetS prevalence associated with advanced age in males (p < 0.001) and females (p = 0.002) was observed. MetS was likely among divorced/separated/widowed (p = 0.021) and high income males (p = 0.002) and females (p = 0.017) with high income. Unemployed males (p = 0.008) and females with tertiary education (p = 0.019) were less likely to have MetS. Advanced age was likely to lead to high blood pressure, fasting blood glucose and triglycerides (p < 0.05). Males were more likely (p = 0.026) to have raised triglycerides, while females (p < 0.001) had low high density lipoproteins. CONCLUSION A high prevalence of MetS associated with social and gender differences among Kenyan adults with central obesity. These underscore the need to look beyond the behavioral and biological risks and focus on every nuance of gender differences in addressing MetS and CVDs.

Diagnostic accuracy of the Finnish Diabetes Risk Score for the prediction of undiagnosed type 2 diabetes, prediabetes, and metabolic syndrome in the Lebanese University. Diabetol Metab Syndr 2020; 12:84. [PMID: 33014142 PMCID: PMC7526372 DOI: 10.1186/s13098-020-00590-8] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Accepted: 09/19/2020] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND Risk scores were mainly proved to predict undiagnosed type 2 diabetes mellitus (UT2DM) in a non-invasive manner and to guide earlier clinical treatment. The objective of the present study was to assess the performance of the Finnish Diabetes Risk Score (FINDRISC) for detecting three outcomes: UT2DM, prediabetes, and the metabolic syndrome (MS). METHODS This was a prospective, cross-sectional study during which employees aged between 30 and 64, with no known diabetes and working within the faculties of the Lebanese University (LU) were conveniently recruited. Participants completed the FINDRISC questionnaire and their glucose levels were examined using both fasting blood glucose (FBG) and oral glucose tolerance tests (OGTT). Furthermore, they underwent lipid profile tests with anthropometry. RESULTS Of 713 subjects, 397 subjects (55.2% female; 44.8% male) completed the blood tests and thus were considered as the sample population. 7.6% had UT2DM, 22.9% prediabetes and 35.8% had MS, where men had higher prevalence than women for these 3 outcomes (P = 0.001, P = 0.003 and P = 0.001) respectively. The AUROC value with 95% Confidence Interval (CI) for detecting UT2DM was 0.795 (0.822 in men and 0.725 in women), 0.621(0.648 in men and 0.59 in women) for prediabetes and 0.710 (0.734 in men and 0.705 in women) for MS. The correspondent optimal cut-off point for UT2DM was 11.5 (sensitivity = 83.3% and specificity = 61.3%), 9.5 for prediabetes (sensitivity = 73.6% and specificity = 43.1%) and 10.5 (sensitivity = 69.7%; specificity = 56.5%) for MS. CONCLUSION The FINDRISC can be considered a simple, quick, inexpensive, and non-invasive instrument to use in a Lebanese community of working people who are unaware of their health status and who usually report being extremely busy because of their daily hectic work for the screening of UT2DM and MS. However, it poorly screens for prediabetes in this context.

Abstract
PURPOSE Metabolic syndrome (MetS) has become a public health challenge in low-income countries due to changing lifestyle and the food environment. However, studies on the prevalence of metabolic syndrome and associated factors are limited in Ethiopia. Therefore, this study assessed the prevalence of MetS and its associated factors among working adults in eastern Ethiopia. METHODS A cross-sectional study was conducted involving 1,164 working adults from December 2018 to February 2019. Data were collected following the World Health Organization (WHO) STEPwise approach. The data collection tools include a structured questionnaire, anthropometric, and biochemical measurements. Prevalence was calculated using International Diabetes Federation criteria. A Poisson regression model with robust variance estimation was used to investigate the independent variable's association with MetS. An adjusted prevalence ratio with 95% confidence interval was reported to show associations. RESULTS The prevalence of MetS was 20.1% (95% CI=17.8-22.4) among the participants. It was more prevalent among females (APR:=1.62, 95% CI=1.31-2.00), those of 35-44 years of age (APR:=3.14, 95% CI=1.19-8.28), 45-54 years of age (APR=4.42, 95% CI=1.66-11.77), and 55-64 years of age (APR=6.03, 95% CI=2.27-16.06), khat chewers (APR=1.30, 95% CI=1.06-1.60), those with 8 or more hours of sedentary behavior (APR=2.29, 95% CI=1.88-2.80), and those consuming alcohol 5-6 days per week (APR=1.81, 95% CI=1.20-2.74). The prevalence was significantly lower in those eating five or more fruits and vegetables servings per day (APR=0.04, 95% CI=0.01-0.27). CONCLUSION A high prevalence of MetS was observed among working adults in eastern Ethiopia. Strengthening workplace health promotion programs is necessary to reduce the negative consequences of MetS in workplaces and protect productivity.

Abstract
Introdução: A obesidade é um problema de saúde pública mundial. Além das diversas alterações metabólicas encontradas em indivíduos obesos, há evidências de alterações no sistema endócrino, como observado no metabolismo da vitamina D.Objetivos:Avaliar a frequência de deficiência de vitamina D em uma amostra de pacientes adultos com obesidade.Materiais e métodos: Foi realizado um estudo transversal retrospectivo analisando 183 prontuários dos pacientes atendidos pela primeira vez buscando tratamento para obesidade. Após os fatores de exclusão, restaram 113 prontuários válidos.Resultados: O IMC variou de 30.1 a 77.1, com uma mediana de 44.5 kg/m2. Trinta pacientes (26,55 %) tinham a Vitamina D abaixo de 20 ng/ml, sendo considerados com diagnóstico de Deficiência de Vitamina D. Nenhum correlação foi encontrada entre os níveis de Vitamina D e os parâmetros antropométricos. Houve associação significativa estatística dos níveis de Vitamina D com colesterol total (r=-0.26; p=0.0053), LDL-colesterol (r=-0.25; p=0.0071), além de uma tendência à significância com os níveis de TGP (r=0.16; p=0.088).Conclusão: Houve uma elevada frequência de deficiência de vitamina D em pacientes obesos. Não houve correlação entre os níveis de vitamina D e os marcadores antropométricos, porém foi encontrada uma correlação inversa de vitamina D com níveis de colesterol total e LDL-colesterol, mostrando a relação com a dislipidemia. Também, houve uma tendência à significância com os níveis de TGP, o que provavelmente remete à esteatose hepática, comum em obesos.
