Methods: A cross-sectional study enrolled 763 adolescents in Kuwait.

Increased LRG1 Levels in Overweight and Obese Adolescents and Its Association with Obesity Markers, Including Leptin, Chemerin, and High Sensitivity C-Reactive Protein.

Leucine-rich α-2 glycoprotein1 (LRG1) is a member of the leucine-rich repeat (LRR) family that is implicated in multiple diseases, including cancer, aging, and heart failure, as well as diabetes and obesity. LRG1 plays a key role in diet-induced hepatosteatosis and insulin resistance by mediating the crosstalk between adipocytes and hepatocytes. LRG1 also promotes hepatosteatosis by upregulating de novo lipogenesis in the liver and suppressing fatty acid β-oxidation.

Vitamin D level in relation to depression symptoms during adolescence.

Background: This study aimed to investigate the association between 25-hydroxyvitamin D (25(OH)D) and depression symptoms among adolescents in Kuwait, a country with a high prevalence of vitamin D deficiency.

Methods: A school based cross-sectional study was conducted on randomly selected 704 adolescents in middle schools. Data on depression symptoms were collected using the Children's Depression Inventory (CDI).

Is age of menarche directly related to vitamin D levels?

Introduction: Very few studies have examined the direct link between age of menarche and vitamin D level and controversial results have been reported. This study aimed to investigate the association between vitamin D and age of menarche in a group of adolescent girls in an area with plenty of sunshine.

Methods: At baseline, data were collected on 722 middle schoolgirls that were randomly selected by probability proportional to size sampling method.

Psychometric properties of the Arabic version of the hospital anxiety and depression scale in hemodialysis patients.

The literature lacks a rigorous psychometric evaluation of the Arabic version of Hospital Anxiety and Depression Scale (HADS) in hemodialysis (HD) patients. This study aims to evaluate reliability, determine the underlying factor structure of the Arabic version of HADS and assess its suitability as screening tool for depression and anxiety among Arabic HD patients.A sample of 370 HD patients were recruited from all health districts in Kuwait.

Profiling of Insulin-Like Growth Factor Binding Proteins (IGFBPs) in Obesity and Their Association With Ox-LDL and Hs-CRP in Adolescents.

Insulin-like growth factor binding proteins (IGFBPs) are critical modulators of metabolism. In adults, IGFBPs are associated with obesity and insulin resistance. However, the association of IGFBPs with metabolic homeostasis in children and adolescents is not yet fully characterized.

Association of blood lead level with vitamin D binding protein, total and free 25-hydroxyvitamin D levels in middle-school children.

A negative association between blood Pb level (BPbL) and vitamin D metabolites in occupationally exposed populations has been reported, but data from the general population are scarce. Furthermore, the association between BPbL and vitamin D binding protein (DBP) and free 25-hydroxyvitamin D (25(OH)D) has not been reported. We investigated the association of BPbL with DBP, total and free 25(OH)D in healthy adolescents (n 1347; age range 11-16 years) cross-sectionally selected from all Governorates of Kuwait, utilising multi-stage cluster random sampling.

Prevalence of depression, anxiety, and their associations among end-stage renal disease patients on maintenance hemodialysis: a multi-center population-based study.

Depression and anxiety are the most common mood disorder among end-stage renal disease (ESRD) patients, which can negatively affect quality-of-life and treatment outcomes. This study aimed to estimate the prevalence of depression and anxiety symptoms among ESRD patients undergoing hemodialysis (HD) and test associations with several covariates. In across-sectional study, we collected data from 457 patients using Hospital Anxiety and Depression Scale (HADS).

Plasma 25-hydroxyvitamin D is positively associated with folate and vitamin B levels in adolescents.

Vitamin D affects the absorption of folate in vitro, and perhaps of vitamin B (B). However, epidemiological studies on the association of vitamin D with folate and B are inconclusive. We hypothesized a positive association of plasma 25-hydroxyvitamin D [25(OH)D] with folate and B levels in adolescents.

The routine chemiluminescence assay for plasma 25-hydroxyvitamin D analysis does not overestimate the prevalence of vitamin D deficiency in adolescents.

Vitamin D deficiency (VDD) is a global public health problem. Inaccurate methods for measuring plasma 25-hydroxyvitamin D (25[OH]D) may have contributed to the reported high prevalence of VDD. We hypothesized that the most commonly used assay for vitamin D status, chemiluminescence immunoassay (CLIA), underestimates 25(OH)D levels and thus overestimates VDD.

Correlation of circulating ANGPTL5 levels with obesity, high sensitivity C-reactive protein and oxidized low-density lipoprotein in adolescents.

Angiopoietin-like proteins (ANGPTL) is a family of eight members known to play an important role in metabolic diseases. Of these, ANGPTL5 is suggested to regulate triglyceride metabolism and is increased in obesity and diabetes. However, its role in metabolic diseases in adolescents is not well-studied.

Season of birth and sugary beverages are predictors of Raven's Standard Progressive Matrices Scores in adolescents.

To investigate factors associated with cognitive functioning in healthy adolescents, a school-based cross-sectional study was conducted on 1370 adolescents aged 11-16 years that were randomly selected from all governorates of Kuwait. Raven's Standard Progressive Matrices (SPM), a non-verbal test of intelligence, was used to measure cognitive functioning of the study participants. Data on predictors of cognitive functioning were collected from parents and adolescents.

Anemia and its associated factors among Adolescents in Kuwait.

We estimated the prevalence of anemia among school children and investigated factors associated with this problem in Kuwait. A cross-sectional study was conducted on 1415 adolescents randomly selected from middle schools in Kuwait.

Objectives: The prevalence of acne vulgaris (AV) among adolescents in Kuwait has remained mostly unknown. This study aimed to estimate the prevalence of AV and its predictors among adolescents in Kuwait.

Subjects And Methods: A cross-sectional study was conducted on 714 participants who were randomly selected from public schools using multistage cluster random sampling.

Plasma 25-Hydroxy Vitamin D is not Associated with Acne Vulgaris.

Few studies have investigated the association between Acne vulgaris (AV) and vitamin D level. In this study we aimed to investigate the association between 25-hydroxyvitamin D (25-OH-VitD) level and AV in a country with plenty of sunshine. A cross-sectional study was conducted on 714 adolescents who were randomly selected from public schools using multistage cluster random sampling with probability proportional to size.

Plasma 25-Hydroxy Vitamin D Is Not Associated with Either Cognitive Function or Academic Performance in Adolescents.

Several observational studies have reported an association between low levels of vitamin D (VD) and poor cognition in adults, but there is a paucity of data on such an association in adolescents. We investigated the association between VD and cognitive function or academic achievement among 1370 adolescents, who were selected from public middle schools in Kuwait, using stratified multistage cluster random sampling with probability proportional to size. Plasma 25-hydroxy VD (25-OH-D) was measured using liquid chromatography-tandem mass spectrometry (LC-MS/MS).
