Altered bile acids profile is a risk factor for hyperandrogenism in lean women with PCOS: a case control study.

The levels of fasting-state serum bile acids (BAs) in individuals with polycystic ovary syndrome (PCOS) differ from those of control subjects. However, there is a lack of research on the BAs profile in lean women with PCOS and whether these changes are linked to the host metabolism. Therefore, our objective was to investigate the synthesis and metabolism of serum BAs in lean women with PCOS and assess the correlation between BAs and clinical characteristics. This study employed a cross-sectional design of lean women with PCOS (n = 240) in comparison to a control group (n = 80) consisting of healthy lean women. The findings revealed significant increases in the levels of non-12-OH BAs and chenodeoxycholic acid (CDCA)% (both P < 0.05) in lean women with PCOS. Additionally, a positive correlation was observed between CDCA% and total testosterone (T) (r = 0.130, P = 0.044) and free androgen index (FAI) (r = 0.153, P = 0.019). Furthermore, a decreased ratio of cholic acid/chenodeoxycholic acid (CA/CDCA) (P < 0.001) was observed in lean women with PCOS, suggesting the depletion or downregulation of CYP8B1. Receiver operating characteristic curve analysis indicated that the combination of CDCA/CA and DHEAS could potentially be used as a characteristic factor for PCOS in lean women. It is possible that enzymatic modifications in the liver could play a role in regulating hyperandrogenism in this specific subgroup of lean women with PCOS.

Clinical-exome sequencing unveils the genetic landscape of polycystic ovarian syndrome (PCOS) focusing on lean and obese phenotypes: implications for cost-effective diagnosis and personalized treatment.

Polycystic ovarian syndrome (PCOS) is one of the most common endocrinopathies among reproductive women worldwide, contributing greatly on the incidence of female infertility and gynecological cancers. It is a complex health condition combining of multiple symptoms like androgen excess, uncontrolled weight gain, alopecia, hirsutism, etc. Conventionally PCOS was associated with obesity while it is often found among lean women nowadays, making the disease more critical to diagnose as well treatment. The disorder has an impact on several signal transduction pathways, including steroidogenesis, steroid hormone activity, gonadotrophin regulation, insulin secretion, energy balance, and chronic inflammation. Understanding the aetiology and pathophysiology of PCOS is difficult due to its multiple causes, which include environmental factors, intricate genetic predisposition, and epigenetic modifications. Despite research supporting the role of familial aggregations in PCOS outcomes, the inheritance pattern remains unknown. Henceforth, to reduce the burden of PCOS, it is inevitably important to diagnose at early ages as well as intervene through personalized medicine. With this brief background, it was imperative to elucidate the genetic architecture of PCOS considering BMI as an controlling factor. This study aims to investigate the genetic basis behind obesity-mediated PCOS, focusing on both obese and lean individuals. It uses a comprehensive bioinformatics methodology to depict pathways and functionality enrichment, allowing for cost-effective risk prediction and management. In the present research, the representative study participants (N = 2) were chosen from a cross-sectional epidemiological survey, based on their anthropometric parameters and confirmation of PCOS. Upon voluntary participation and written consent, biological fluids (whole blood and buccal swab) were taken from where DNA was extracted. The clinical-exome sequencing was performed by the Next-generation Illumina platform using the Twist Human Comprehensive Exome Kit. A comprehensive bioinformatics methodology was employed to identify the most important, unique, and common genes. A total of 26,550 variants were identified in clinically important exomes from two samples, with 5170 common and 2232 and 2322 unique among PCOS lean and obese phenotypes, respectively. Only 262 and 94 variants were PCOS-specific in lean and obese PCOS. Three filters were applied to shortlist the most potent variants, with 4 unique variants in lean PCOS, 2 unique variants in obese PCOS, and 5 common variants in both. The study found that leptin signalling impairment and insulin resistance, as well as mutations in CYP1A1, CYP19A1, ESR1, AR, AMH, AdipoR1, NAMPT, NPY, PTEN, EGFR, and Akt, all play significant roles in PCOS in the studied group. Young women in West Bengal, India, are more likely to have co-occurring PCOS, which includes estrogen resistance, leptin receptor insufficiency, folate deficiency, T2DM, and acanthosis nigricans, with obesity being a common phenotypic expression.

Temporal trend in markers of nutritional status and food consumption of non-village indigenous people in Brazil.

BACKGROUND: Non-village indigenous people may face urban lifestyle influences, impacting their nutritional profile. Therefore, this study aimed to analyze the temporal trends in the nutritional status (2008-2023) and food consumption (2015-2023) of non-village indigenous people in Brazil, using data from the Food and Nutrition Surveillance System (SISVAN). METHODS: In this time series study, secondary data available on the SISVAN online platform were used. All records of non-village indigenous people from all regions of Brazil were evaluated. Nutritional status was assessed using height-for-age (H/A) and Body Mass Index-for-age (BMI/A) for children and adolescents, and BMI for adults and the elderly. Food consumption trends were analyzed using food consumption screeners, based on specific food groups consumed the day before the assessment. An annual percentage change (APC) was calculated using Prais-Winsten regression models. RESULTS: There was a reduction in severe stunting among children aged 2 to 4 years old (APC = -0.80%; p = 0.025) and 5 to 9 years old (APC = -4.02%; p < 0.001). Adolescents showed an increase in thinness (APC = 0.91%; p = 0.016) and obesity (APC = 4.38%; p < 0.001). In adults and the elderly, there was a decrease in underweight (APC = -5.59%; p = 0.002 and APC = -3.12%; p < 0.001, respectively) and an increase in obesity grade 1 and overweight (APC = 3.81%; p < 0.001 and APC = 1.82%; p < 0.001, respectively). There was an increase in vegetable consumption among children, adolescents and the elderly, and a rise in the consumption of hamburgers and sausages across all age groups. CONCLUSION: There was an improvement in the nutritional status of children and adolescents, with reduced stunting, but a rise in obesity among adolescents, adults and the elderly. Food consumption trends showed increased consumption of vegetables and ultra-processed foods.

Patterns of change in the association between socioeconomic status and body mass index distribution in India, 1999-2021.

Background: Body mass index (BMI) is an important indicator of human health. However, trends in socioeconomic inequalities in BMI over time throughout India are understudied. Filling this gap will elucidate which socioeconomic groups are still at risk for adverse BMI values. Methods: This repeated cross-sectional study analysed four rounds of India's National Family Health Surveys (1998-1999, 2005-2006, 2015-2016, and 2019-2021). The outcome was BMI categories, measured in kilogram per metres squared (kg/m2), defined as severely/moderately thin (<17.0 kg/m2), mildly thin (17.0-18.4 kg/m2), normal (18.5-24.9 kg/m2), overweight (25.0-29.9 kg/m2), and obese (≥30.0 kg/m2). We examined the prevalence, standardised absolute change, and odds ratios estimated by multivariable regression models by household wealth and levels of education, two important measures of socioeconomic status (SES). Results: The study population consisted of 1 244 149 women and 227 585 men. We found that those in the lowest SES categories were more likely to be severely/moderately thin or mildly thin. Conversely, those in the highest SES groups were more likely to be overweight or obese. The gradients were steepest for wealth, and this was substantiated by the results of regression models for every wave. There has been a decline in the difference in the prevalence of severely/moderately thin or mildly thin between SES groups when comparing the years 1999 and 2021. Conclusions: SES-based inequalities in BMI were smaller in 2021 compared to 1999. However, those in low SES groups were most likely to be severely/moderately thin or mildly thin while those in high SES groups were more likely to be overweight or obese. Future research should explore the pathways that link SES with BMI.

Correlation of body mass index, with cardiometabolic and cardiorespiratory fitness in health care professionals of Multan.

The current study was conducted at Ali-Ul-Murtaza Department of Rehabilitation Sciences, Muhammad Institute of Medical and Allied Sciences, Multan, Pakistan, from October to December 2022 to explore the correlation of body mass index with cardiometabolic and cardiorespiratory parameters in 393 male and female healthcare professionals, including physiotherapists, pharmacists and medical laboratory technicians, aged 22- 40 years. The evaluation was on the basis of the Physical Activity Readiness Questionnaire, body mass index, lipid profile, body fat and correlation of blood pressure, temperature, oxygen saturation, respiration rate and heart rate with cardiorespiratory fitness assessed through shuttle-run test, step test and treadmill test. Data was analysed using SPSS 25. Of the 393 subjects, 140(35.62) were underweight, 140(35.62) were overweight and 113(28.75) were obese. Of the total, 153(38.93) were pleased with their general health, while 240(61.06) had a history of cardiovascular and metabolic conditions. There was a highly significant correlation between lipid profiles and the subjects' quality of life (p<0.05).

The Role of Complementary Feeding Practices in Addressing the Double Burden of Malnutrition among Children Aged 6-23 Months: Insight from the Vietnamese General Nutrition Survey 2020.

Background/Objectives: Optimal infant and young child feeding (IYCF) practices are crucial to addressing the double burden of malnutrition (DBM), encompassing undernutrition (including micronutrient deficiencies) and overnutrition. This study examined the demographic and socioeconomic determinants of IYCF practices, and their impacts on the DBM among 2039 Vietnamese children aged 6-23 months from the General Nutrition Survey 2020. Methods: Thirteen IYCF indicators recommended by the WHO/UNICEF were evaluated. Associations between IYCF indicators and outcome variables were assessed using logistic regressions. Results: The prevalence of stunting, underweight, and overweight subjects was 10.9%, 5.6%, and 3.1%, respectively. Low serum zinc affected 56.7% of children, while 14.3% had low serum retinol, 31.2% had anemia, and 34.6% had iron deficiency (ID). Only 36.7% of children achieved minimum dietary diversity (MDD), and 29.0% achieved the minimum acceptable diet (MAD). Children from the younger age group (6-11 months), ethnic minorities, those living in rural/mountainous regions, and poorer wealth quintiles had reduced odds of meeting IYCF criteria, including MDD and MAD. Infants meeting MDD had reduced odds of stunting [adjusted odds ratio (95% confidence intervals): 0.61 (0.41, 0.92)], and ID [0.69 (0.54, 0.88)]. Children meeting MAD had reduced odds of anemia [0.72 (0.57, 0.91)], ID [0.66 (0.52, 0.84)], and low serum retinol [0.63 (0.41, 0.99)]. Continued breastfeeding (12-23 months) reduced the odds of being underweight [0.50 (0.27, 0.92)] and of having low serum zinc [0.70 (0.52, 0.96)]. Adequate minimum milk feeding frequency had increased odds of being overweight [3.33 (1.01, 11.09)]. Conclusions: Suboptimal IYCF practices were significant predictors of the DBM among Vietnamese children, with evident age-specific, geographical, and socioeconomic disparities.

The influence of minimum dietary diversity on undernutrition among children aged 6-23 months in Ethiopia: a multilevel mixed-effect analysis based on 2019 Ethiopian mini demographic and health survey.

Background: Undernutrition persists as a critical issue in developing countries like Ethiopia due to poor feeding practices for infants and young children. The impact of dietary diversity on children's health in Ethiopia remains unclear, necessitating further investigation to develop effective prevention strategies. Objective: To examine the association between minimum dietary diversity and undernutrition among children aged 6-23 months in Ethiopia. Methods: Data from the 2019 Ethiopian Mini Demographic and Health Survey, including 1,501 women with children aged 6-23 months, were analyzed using STATA version 17 software. Child stunting, wasting, and underweight were assessed using Z-scores. Dietary diversity was measured using minimum dietary diversity. Multilevel logistic regression analysis determined associations, presenting results as crude odds ratios (COR) and adjusted odds ratios (AOR) with 95% confidence intervals (CI). Results: Overall, 10.99% of children had adequate minimum dietary diversity, with Addis Ababa (44.57%) and Somalia (1.47%) showing the highest and lowest prevalences, respectively. The highest stunting prevalence was in the Amhara region (45.86%), while Addis Ababa had the lowest (9.78%). Wasting was lowest in Addis Ababa (1.09%) and highest in Tigray (17.07%). Underweight prevalence ranged from 2.17% in Addis Ababa to 33.33% in Tigray. Children with adequate minimum dietary diversity (MDD) had significantly lower odds of stunting (AOR = 0.68, 95% CI = 0.45, 0.96), underweight (AOR = 0.51, 95% CI = 0.27, 0.99), and wasting (AOR = 0.40, 95% CI = 0.17, 0.97) compared to those who had inadequate minimum dietary diversity (MDD). Conclusion: This study highlights the association between minimum dietary diversity and stunting, wasting, and underweight among Ethiopian children aged 6-23 months. Urgent nutrition-specific interventions are needed, particularly in regions with high undernutrition rates and low dietary diversity. Targeted interventions focusing on promoting diverse and nutritious diets for children, along with improving access to essential healthcare services, are imperative to mitigate the burden of undernutrition and ensure the well-being of Ethiopia's youngest population and reinforcing existing programs is crucial to address this public health issue effectively.

Adipose tissue insulin resistance in young Japanese women is associated with metabolic abnormalities and dehydroepiandrosterone-sulfate.

Objective: The proportion of young Japanese women who are underweight is exceptionally high. We previously showed that the prevalence of impaired glucose tolerance (IGT) was high in underweight young Japanese women, and that IGT was characterized by high free fatty acid levels and adipose tissue insulin resistance (ATIR). As the next step, this study aimed to explore factors associated with elevated ATIR in this population. Participants: Ninety-eight young, healthy, underweight women participated in this study. Design: To investigate the relationship between ATIR and metabolic parameters, participants were divided into three groups (Low, Medium, and High) according to ATIR level. Body composition examination, oral glucose tolerance testing, and blood biochemical analysis were performed; Adipo-IR and the Matsuda index were used as indices of ATIR and systemic insulin sensitivity, respectively. Results: Participants in the High ATIR group had the highest prevalence of IGT (25%), and significantly higher body fat percentage, whole-body insulin resistance, and levels of insulin-like growth factor-1 and dehydroepiandrosterone sulfate (DHEA-S) than the other two groups. They were also significantly younger and had higher systolic blood pressure than the Low ATIR group. Multiple regression analysis showed that DHEA-S, which is known to enhance lipolysis in adipose tissue, was an independent correlate of ATIR. Conclusions: Underweight Japanese women with high ATIR had impaired metabolism, a higher prevalence of IGT, higher systemic insulin resistance, and higher systolic blood pressure. DHEA-S was a determinant of high ATIR levels.

Reducing stunting and underweight through mother's birth spacing: evidence from Ghana.

BACKGROUND: Researchers over the years have underscored the role of birth spacing on maternal health, however, inadequate maternal repletion due to shorter birth intervals could also affect the health of the child. Even so, limited studies exist on the linkage between birth spacing and child nutrition. This study examines the association between birth spacing and child stunting and underweight using the 2014 Ghana Demographic and Health Survey. METHODS: The study sourced data on 1, 904 children less than 59 months from the 2014 Ghana Demographic and Health Survey. The study employed bivariate analysis and logistic regressions to establish the association between birth spacing, and child stunting and underweight. RESULTS: The analyses reveal that childbirth spacing between 24 and 35 months (OR = 0.62, 95% CI: 0.38-0.99; p < 0.05), 36 to 47 months (OR = 0.42, 95% CI: 0.25-0.70; p < 0 0.01), and beyond 47 months (OR = 0.47, 95% CI: 0.28-0.78; p < 0.01) have lower odds of child stunting than children with birth spacing less than 24 months. Children with birth spacing between 24 and 35 months (OR = 0.53, 95% CI: 0.29-0.98; p < 0.05), 36 to 47 months (OR = 0.44, 95% CI: 0.22-0.90; p < 0.01) and beyond 47 months (OR = 0.49, 95% CI: 0.26-0.94; P < 0.05) have lower odds of being underweight than those with birth spacing less than 24 months. CONCLUSION: The study reveals that mothers with a birth spacing of at least two to three years compared to their counterparts with less than two years of birth spacing have lower odds of having a stunted and underweight child under age five. The study recommends that Ghana Health Service and other healthcare providers should educate mothers on the gains of birth spacing of at least two years on their children.

Nutritional status and adherence to anti-tubercular treatment among tuberculosis patients in a community development block of Eastern India.

BACKGROUND: Undernutrition is a risk factor for developing tuberculosis (TB) and adherence to treatment leads to successful treatment outcomes. OBJECTIVES: To assess the nutritional status and adherence to treatment among tuberculosis patients in Bhatar Community Development Block of Purba Bardhaman district, West Bengal, India. MATERIAL & METHODS: A cross sectional descriptive study was conducted among all the 82 tuberculosis patients registered between April to June, 2021, under NTEP in Bhatar tuberculosis unit (TU), who completed at least 1 month of therapy. Nutritional status was assessed based on BMI and adherence to treatment was evaluated by interviewing with a validated version of Morisky Medication Adherence Scale (MMAS-8-Item). Data was analysed using SPSS v23. RESULTS: Among the 82 subjects, 51 (62.2%) were found to be underweight and overall high level of adherence to treatment was found among 51 (62.2%) of study subjects. Subjects aged >45 years (AOR 3.686, 95% CI: 1.147-11.842) and having extra-pulmonary Tuberculosis (AOR 8.539, 95% CI: 1.305-55.871) were significantly associated as being adherent to treatment. CONCLUSION: Health education, awareness and more vigilant monitoring is still needed so that TB patients can be cured successfully. Special attention needs to be given on the nutritional status of the TB patients.

The prevalence of obesity and underweight in celiac patients at the time of diagnosis: a systematic review and meta-analysis.

BACKGROUND: This study aimed to estimate the prevalence of obesity, overweight, and underweight in celiac disease (CD) at diagnosis before starting the Gluten-free diet (GFD). METHODS: A comprehensive search was conducted in PubMed, Embase, Scopus, and Web of Science until July 2024 to find the cross-sectional and longitudinal studies that measured the body mass index (BMI) in CD patients at diagnosis. The risk of bias assessment was conducted using the Newcastle-Ottawa Quality Assessment scale. Meta-regression analyses were applied to understand whether weight status is associated with CD. RESULTS: A total of 23 studies involving 15,299 CD patients and 815,167 healthy individuals were included in this study. In newly diagnosed CD patients, pooled estimates of the prevalence of obesity, overweight, and underweight before GFD were 11.78%, 18.42%, and 11.04%, respectively. The prevalence of overweight and obesity in newly diagnosed CD patients increased from 22.15% in 2003-2009 to 32.51% in 2016-2021. Meta-regression analyses indicated that the CD patients with higher BMI had a higher mean age (p = 0.001), and female gender had a marginally significant (p = 0.055) association with higher BMI. Only a few CD patients were underweight at the time of diagnosis, and more patients were overweight/obese. CONCLUSIONS: our meta-analysis demonstrated that only a few CD patients were underweight at the time of diagnosis, and almost 37% were overweight or obese. Meta-regression showed a significant association between higher BMI and higher mean age and female gender. A delay or failure for diagnosis of CD is more common in overweight/obese patients, resulting in more progression of the disease and counteracting any advantages of diagnosis.

Effect of antenatal use of high energy nutritional supplements on cardio metabolic risk markers in underweight primi gravidas; a randomized controlled trial.

BACKGROUD: Pregnancy is a state of increased metabolic demand, and poor maternal nutrition can exacerbate these changes, potentially increasing the risk of cardiometabolic disorders.This study is significant as it investigates the effect of high energy nutritional supplements on cardio metabolic risk markers in underweight primigravidas. METHODOLOGY: A single blinded randomized controlled trial was conducted from April 2018- August 2019 among the Pakistani tertiary care facilities of Khyber Pakhtunkhwa. A total of thirty six participants were randomized into two groups receiving either high energy nutritional supplement 'MAAMTA' or Placebo. They were instructed to take Placebo/Supplement alongside to their regular prenatal care and food from their first antenatal visit till a week postnatally. Anthropometric measurements and blood samples for biochemical parameters insulinlevels, fasting blood glucose & lipid profile were taken at baseline visit, between 16 and 20 weeks gestation and a post natal visit. RESULTS: The two-way repeated measures ANOVA showed that there was a highly significant time effect on participant's Insulin level (F (1.8, 53.6) = 10.64, P < 0 0.000, ηp2 = 0.269). A highly significant time effect on participant's insulin resistance (F (2, 68) = 8.116,P < 0 0.001, ηp2 = 0.193) was also observed. There was a highly significant time effect on participant's LDL level as well (F (2, 68) = 11.82, P < 0 0.000, ηp2 = 0.258). CONCLUSION: Supplementation with high energy nutritional supplements may improve insulin levels and insulin sensitivity in underweight primigravidas. TRIAL REGISTRATION: https://www.

Exploring the correlation between body mass index and lung function test parameters: a cross-sectional analytical study.

PURPOSE: The correlation between body weight and health is a significant public health concern. While the adverse effects of obesity on pulmonary function are well-known, the impact of being underweight remains debated due to limited research. This study aimed to investigate the correlation between Body Mass Index (BMI) categories and lung function parameters. RESULTS: A study of 3077 participants found significant differences in gender, age, height, and weight across various Body Mass Index (BMI) categories. The study found non-significant variations in forced expiratory flow (FVC) across BMI categories, with underweight individuals showing lower FVC compared to normal and overweight individuals. BMI significantly impacted mean forced expiratory flow during the middle half of FVC. A significant negative correlation was observed between age and FVC, FEV1, FEV1/FVC ratio, and FEF25-75. A significant positive correlation was observed between weight, height, and lung function parameters. Multiple regression analysis revealed a decrease in lung function with advancing age, while height showed significant positive associations. The study concluded that age, sex, smoking, height, and weight collectively explained 41.0% of the variance in FVC, FEV, and FEF25-75.

Proteo-genomic analyses in relatively lean Chinese adults identify proteins and pathways that affect general and central adiposity levels.

Adiposity is an established risk factor for multiple diseases, but the causal relationships of different adiposity types with circulating protein biomarkers have not been systematically investigated. We examine the causal associations of general and central adiposity with 2923 plasma proteins among 3977 Chinese adults (mean BMI = 23.9 kg/m²). Genetically-predicted body mass index (BMI), body fat percentage (BF%), waist circumference (WC), and waist-to-hip ratio (WHR) are significantly (FDR < 0.05) associated with 399, 239, 436, and 283 proteins, respectively, with 80 proteins associated with all four and 275 with only one adiposity trait. WHR is associated with the most proteins (n = 90) after adjusting for other adiposity traits. These associations are largely replicated in Europeans (mean BMI = 27.4 kg/m²). Two-sample Mendelian randomisation (MR) analyses in East Asians using cis-protein quantitative trait locus (cis-pQTLs) identified in GWAS find 30/2 proteins significantly affect levels of BMI/WC, respectively, with 10 showing evidence of colocalisation, and seven (inter-alpha-trypsin inhibitor heavy chain H3, complement factor B, EGF-containing fibulin-like extracellular matrix protein 1, thioredoxin domain-containing protein 15, alpha-2-antiplasmin, fibronectin, mimecan) are replicated in separate MR using different cis-pQTLs identified in Europeans. These findings identified potential novel mechanisms and targets, to our knowledge, for improved treatment and prevention of obesity and associated diseases.

Changing paradigm of malnutrition among Bangladeshi women of reproductive age and gaps in national Nutrition Policies and Action Plans to tackle the emerging challenge.

Objective: The main objective of this paper is to document the changing paradigm of malnutrition in Bangladesh and estimating how this is creating an intergenerational risk. This paper also examines national policy responses to tackle the silent epidemic of double burden of malnutrition. Methods: Publicly available datasets of five Bangladesh Demographic and Health Surveys were used to see the changing paradigm of malnutrition among Bangladesh women. In addition to that, four national policies concerning, maternal and child health; and nutrition were reviewed using CDC's 2013 Policy Analytical Framework. Results: In Bangladesh, the share of ever-married women aged 15-49 who were underweight declined sharply between 2007 and 2017-2018, from 30 to 12%. In the same period, the proportion of women who were overweight or obese increased from 12 to 32%. Despite remarkable progress in reducing undernourishment among women, the share of well-nourished remained unchanged: 58% in 2007 and 56% in 2017-2018, mainly due to the shift in the dominant burden from undernutrition to overnutrition. This shift occurred around 2012-2013. Currently, in Bangladesh 0.8 million of births occur to overweight women and 0.5 million births occur to underweight women. If the current trend in malnutrition continues, pregnancies/births among overweight women will increase. Bangladesh's existing relevant policies concerning maternal health and nutrition are inadequate and mostly address the underweight spectrum of malnutrition. Discussion: Both forms of malnutrition pose a risk for maternal and child health. Underweight mothers are at risk of having anemia, antepartum/postpartum hemorrhage, and premature rupture of membranes. Maternal obesity increases the risk of perinatal complications, such as gestational diabetes, gestational hypertension, and cesarean deliveries. Currently, around 24% of the children are born to overweight/obese mothers and 15% to underweight mothers. Bangladesh should revise its national policies to address the double burden of malnutrition among women of reproductive age across pre-conception, pregnancy, and post-natal stages to ensure optimum maternal and child health.

Nutritional status of tribal and non-tribal school-going children in rural Bangladesh: A comparative study.

BACKGROUND: Inadequate nutrition of school-going children is a major concern in Bangladesh, and it can negatively affect their productivity. It is important to consider the food pattern, socio-cultural, and economic differences between tribal (T) and non-tribal (NT) communities in Bangladesh when evaluating their nutritional status. This study aimed to investigate the nutritional status of school-going children in the rural area of Rajshahi district's High Barind Tract (HBT) region of Bangladesh. Additionally, we compared the nutritional status between T and NT school-going children in the same area. METHODS: This was a cross sectional household study. Data were collected from T and NT households in the HBT region in the Rajshahi district of Bangladesh, from January to June of 2019. A total of 500 (T 81, NT 419) school-going children aged 6-13 years were selected as samples using mixed sampling, including convenience sampling (non-probability) and simple random sampling (probability) methods. Nutritional status was assessed using body mass index-for-age z-score (BAZ) and height-for-age z-score (HAZ) according to WHO guidelines. Thinness was defined as BAZ < -2SD and stunting as HAZ < -2SD. Descriptive statistics, Z-proportional test, and logistic regression model were used to analyze the effect of selected independent variables on nutritional status of T and NT children. RESULTS: Among school-going children, 15.20% were suffering from thinness (T 12.30% and NT 15.80%) and 17.80% stunting (T 13.60% and NT 18.60%), respectively. The difference in thinness (p > 0.05) and stunting (p > 0.05) were not significant between T and NT. The distribution of BAZ and HAZ of T and NT children were normally distributed, and were positioned negatively compared to the WHO standards. The logistic model identified the following factors for thinness: (i) mother with non-or-primary education (aOR = 1.89, 95% CI: 1.05-3.43, p < 0.05), (ii) underweight mother (aOR = 3.86, 95% CI: 1.48-10.06, p < 0.01), and (iii) underweight father (aOR = 4.12, 95% CI: 1.50-11.29, p < 0.01). For stunting, the factors were: (i) mother as a housewife (aOR = 2.79, 95% CI: 1.16-6.71, p < 0.05), (ii) father working as labour (aOR = 1.77, 95% CI: 1.01-3.278, p < 0.05), (iii) severe food insecurity in the household (aOR = 2.37, 95% CI: 1.23-4.54, p < 0.05), and (iv) children playing outside regularly more than 2 h (aOR = 2.19, 95% CI: 1.31-3.67, p < 0.01). CONCLUSION: In rural Bangladesh, the nutritional status of T and NT school-going children did not show significant defferences. However, the mean z-score values for both groups of children were lower than the WHO standard, indicating that both communities have poor nutritional status.

Temporal Trends in the Prevalence of Child Undernutrition in China From 2000 to 2019, With Projections of Prevalence in 2030: Cross-Sectional Analysis.

BACKGROUND: Although the problem of malnutrition among children in China has greatly improved in recent years, there is a gap compared to developed countries, and there are differences between provinces. Research on long-term comprehensive trends in child growth failure (CGF) in China is needed for further improvement. OBJECTIVE: The purpose of this study was to examine trends in stunting, wasting, and underweight among children younger than 5 years in China from 2000 to 2019, and predict CGF till 2030. METHODS: We conducted a cross-sectional analysis using data from the local burden of disease (LBD) database. Using Joinpoint Regression Software, we examined trends in CGF among children younger than 5 years in China from 2000 to 2019, and predicted the trends of prevalence in 2030, using the Holt-Winters model with trends but without seasonal components. The assessment was performed with Stata 17 (StataCorp). Data were analyzed from October 17, 2023, to November 22, 2023. RESULTS: In 2019, the prevalences of stunting, wasting, and underweight decreased to 12%, 3%, and 4%, respectively (decreases of 36.9%, 25.0%, and 42.9%, respectively, compared with the values in 2000). The prevalence of CGF decreased rapidly from 2000 to 2010, and the downward trend slowed down after 2010. Most provinces had stagnated processes of trends after 2017. The age group with the highest stunting prevalence was children aged 1 to 4 years, and the highest prevalence of wasting and underweight was noted in early neonatal infants. From 2000 to 2019, the prevalence of CGF declined in all age groups of children. The largest relative decrease in stunting and underweight was noted in children aged 1 to 4 years, and the largest decrease in wasting was noted in early neonatal infants. The prevalences of stunting, wasting, and underweight in China are estimated to decrease to 11.4%, 3.2%, and 4.1%, respectively, by 2030. China has nationally met the World Health Organization's Global Nutrition Targets for 2030 for stunting but not for wasting. CONCLUSIONS: This study provides data on the prevalence and trends of CGF among children younger than 5 years and reports declines in CGF. There remain areas with slow progress in China. Most units have achieved the goal for stunting prevalence but not wasting prevalence.

Conventional and genetic associations of BMI with major vascular and non-vascular disease incidence and mortality in a relatively lean Chinese population: U-shaped relationship revisited.

BACKGROUND: Higher body mass index (BMI) is associated with higher incidence of cardiovascular and some non-cardiovascular diseases (CVDs/non-CVDs). However, uncertainty remains about its associations with mortality, particularly at lower BMI levels. METHODS: The prospective China Kadoorie Biobank recruited >512 000 adults aged 30-79 years in 2004-08 and genotyped a random subset of 76 000 participants. In conventional and Mendelian randomization (MR) analyses, Cox regression yielded adjusted hazard ratios (HRs) associating measured and genetically predicted BMI levels with incident risks of major vascular events (MVEs; conventional/MR 68 431/23 621), ischaemic heart disease (IHD; 50 698/12 177), ischaemic stroke (IS; 42 427/11 897) and intracerebral haemorrhage (ICH; 7644/4712), and with mortality risks of CVD (15 427/6781), non-CVD (26 915/4355) and all causes (42 342/6784), recorded during ∼12 years of follow-up. RESULTS: Overall, the mean BMI was 23.8 (standard deviation: 3.2) kg/m2 and 13% had BMIs of <20 kg/m2. Measured and genetically predicted BMI showed positive log-linear associations with MVE, IHD and IS, but a shallower positive association with ICH in conventional analyses. Adjusted HRs per 5 kg/m2 higher genetically predicted BMI were 1.50 (95% CI 1.41-1.58), 1.49 (1.38-1.61), 1.42 (1.31-1.54) and 1.64 (1.58-1.69) for MVE, IHD, IS and ICH, respectively. These were stronger than associations in conventional analyses [1.21 (1.20-1.23), 1.28 (1.26-1.29), 1.31 (1.29-1.33) and 1.14 (1.10-1.18), respectively]. At BMIs of ≥20 kg/m2, there were stronger positive log-linear associations of BMI with CVD, non-CVD and all-cause mortality in MR than in conventional analyses. CONCLUSIONS: Among relatively lean Chinese adults, higher genetically predicted BMI was associated with higher risks of incident CVDs. Excess mortality risks at lower BMI in conventional analyses are likely not causal and may reflect residual reverse causality.

[Sociodemographic and dietary factors and health conditions: determinants of malnutrition in the elderly in Colombia]. / Factores sociodemográficos, alimentarios y condiciones de salud: determinantes de la malnutrición en personas mayores de Colombia.

This study aimed to estimate the prevalence of malnutrition using clustered anthropometric indicators and to describe the sociodemographic and dietary factors and health conditions that determine malnutrition in elderly Colombians. This was a secondary analysis of the study Health, Well-being and Ageing (SABE) Colombia, 2015. The survey included 23,694 people aged ≥ 60 years. Malnutrition excess was defined by clustering two indicators: body mass index (BMI) and waist circumference; weight deficit was defined by clustering BMI and arm and calf circumferences. The chi-square test was used to associate malnutrition with sociodemographic variables, dietary and health conditions, and to determine the heterogeneity of malnutrition, a latent class analysis was performed. Overweight was 31.9%, whereas underweight, according to BMI and calf circumference, was 7.9%, and increased to 18.8% when arm circumference was also taken into account. Five latent classes of malnutrition were generated - class 1: no overweight and deteriorated health conditions; class 2: no weight deficit and deteriorated health conditions; class 3: no malnutrition and deteriorated health conditions; class 4: overweight and multimorbidity; and class 5: low protein food intake without being underweight or overweight. It is concluded that a high prevalence of malnutrition in older adults exists, with excess rather than deficit. Sociodemographic and dietary factors and health conditions are associated differently with overweight and underweight.

El objetivo del estudio fue estimar la prevalencia de malnutrición por indicadores antropométricos agrupados y describir los factores sociodemográficos, alimentarios y condiciones de salud determinantes de malnutrición en personas mayores colombianas. Se realizó un análisis secundario del estudio Salud, Bienestar y Envejecimiento (SABE) Colombia, 2015. Incluyó 23.694 personas ≥ 60 años. La malnutrición por exceso se definió agrupando dos indicadores: índice de masa corporal (IMC) y circunferencia de cintura; el déficit de peso se definió agrupando el IMC y las circunferencias de brazo y pantorrilla. Para asociar la malnutrición con variables sociodemográficas, alimentarias y condiciones de salud se usó la prueba chi-cuadrado y para determinar la heterogeneidad de la malnutrición se realizó un análisis de clases latentes. El exceso de peso fue 31,9%; mientras que el déficit de peso según IMC y circunferencia de pantorrilla fue 7,9%, e incrementó a 18,8%, al tener en cuenta además la circunferencia del brazo. Se generaron cinco clases latentes para malnutrición, clase 1: sin exceso de peso y con deterioro en condiciones de salud; clase 2: sin déficit de peso y con deterioro en condiciones de salud; clase 3: sin malnutrición ni deterioro en condiciones de salud; clase 4: exceso de peso y multimorbilidad, y clase 5: bajo consumo de alimentos proteicos sin déficit ni exceso de peso. Se concluye que existe una prevalencia de malnutrición elevada en las personas mayores, representando más el exceso que el déficit. Tanto los factores sociodemográficos, alimentarios y condiciones de salud, se asocian de forma diferente al exceso que al déficit de peso.

O objetivo do estudo foi estimar a prevalência da desnutrição por meio de indicadores antropométricos agrupados e descrever os fatores sociodemográficos, alimentares e condições de saúde determinantes da desnutrição em idosos colombianos. Foi realizada uma análise secundária do estudo Saúde, Bem-estar e Envelhecimento (SABE) Colômbia, 2015. A pesquisa incluiu 23.694 pessoas com idade ≥ 60 anos. O excesso de desnutrição foi definido pelo agrupamento de dois indicadores: índice de massa corporal (IMC) e circunferência da cintura; o déficit de peso foi definido pelo agrupamento do IMC e das circunferências do braço e da panturrilha. Para associar a desnutrição a variáveis sociodemográficas, condições alimentares e de saúde, foi usado o teste do qui-quadrado e, para determinar a heterogeneidade da desnutrição, foi realizada uma análise de classe latente. O excesso de peso foi de 31,9%, enquanto o baixo peso, de acordo com o IMC e a circunferência da panturrilha, foi de 7,9%, e aumentou para 18,8% quando a circunferência do braço também foi levada em conta. Foram geradas cinco classes latentes para a desnutrição - classe 1: sem excesso de peso e condições de saúde deterioradas; classe 2: sem déficit de peso e condições de saúde deterioradas; classe 3: sem desnutrição e condições de saúde deterioradas; classe 4: excesso de peso e multimorbidade; e classe 5: baixa ingestão de alimentos proteicos sem déficit de peso ou excesso de peso. Conclui-se que há uma alta prevalência de desnutrição em idosos, com excesso em vez de déficit. Fatores sociodemográficos, alimentares e condições de saúde estão associados de forma diferente ao sobrepeso e ao baixo peso.

Underweight and associated factors among children under age of five in low and lower-middle income African countries: hierarchical analysis of demographic and health survey data.

Introduction: Globally, nearly half of all deaths among children under the age of five are linked to undernutrition. These tragic outcomes are most prevalent in low- and middle-income countries. The far-reaching impact of malnutrition affects not only individuals but also their families, communities, and entire nations. By examining underweight, we gain valuable insights into the intricate network of factors influencing child health. Therefore, this study aims to assess underweight prevalence and its associated factors among under-five children in low and lower-middle-income African countries. Method: We conducted a secondary analysis of standard demographic and health surveys in 30 low and lower-middle-income African countries spanning from 2012 to 2022. Our analysis included a total sample of 200,655 children under the age of 5 years. We employed a three-level hierarchical model to assess the determinants of underweight among children in this age group. Measures of association were evaluated using adjusted odds ratios with a 95% confidence interval. Explanatory variables with a p-value less than the level of significance (0.05) were considered statistically significant. Result: The pooled prevalence of underweight among children under the age of five in low and lower-middle income African countries was estimated at 17.60%, with a 95% confidence interval (CI) ranging from 17.44 to 17.77%. The hierarchical analysis identified several factors significantly associated with underweight, including male gender, birth size, maternal body mass index, maternal educational level, household wealth index, antenatal care (ANC) visits, community poverty level, and income level of countries. Conclusion: The high prevalence of underweight among children under the age of five in low and lower-middle income African countries underscores the need for targeted interventions. By addressing individual, community, and country-level factors, we can work toward improving child nutrition and well-being.
