Neck Circumference and Incidence of Type 2 Diabetes in Chinese Elderly Individuals: A Community-Based Cohort Study

IntroductionThis study aimed to investigate whether neck circumference (NC) was associated with the incidence of type 2 diabetes in Chinese elderly individuals.MethodsA community-based cohort study was conducted on elderly inhabitants in Shanghai with a mean age of 71.0 ± 5.8 years (n = 2,646). Binary logistic regression analysis was performed to evaluate the association between NC and the prevalence of type 2 diabetes, while a Cox regression model was used to determine the association between NC and the incidence of type 2 diabetes after a follow-up of 2 years.ResultsLogistic regression analysis showed that a larger NC was significantly associated with an increased risk for type 2 diabetes in men (odds ratio [OR] 1.18, 95% confidence interval [CI] 1.07–1.31; p = 0.001) and women (OR 1.25, 95% CI 1.13–1.38; p < 0.001). Cox regression analysis revealed that NC was independently associated with the incidence of type 2 diabetes in both men (hazard ratio [HR] 1.14, 95% CI 1.05–1.23; p = 0.002) and women (HR 1.18, 95% CI 1.10–1.27; p < 0.001).ConclusionsA larger NC was associated with a higher risk of developing type 2 diabetes in Chinese elderly individuals. However, studies with larger sample sizes and longer follow-up durations are needed to definitively determine the relationship between NC and the risk of developing type 2 diabetes.     

Body Composition,Sarcopenia, and Suicidal Ideation in Elderly Koreans: Hallym Aging Study

This study was conducted to assess the relationship between body composition and suicidal ideation among the Korean elderly population (n = 302; ≥ 65 years) who participated in the Hallym Aging Study in 2010. Body composition was measured using dual-energy X-ray absorptiometry, and obesity was measured by the indices of body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), and body fat percentage. Sarcopenia was defined as presence of both low muscle mass and low muscle function. Suicidal ideation was assessed using the Beck Scale for Suicide Ideation. We found no differences in body composition measures between subjects with suicidal ideation and those without. In the logistic regression analyses, there were no significant relationships for suicidal ideation according to body composition measures, including BMI, WC, WHR, WHtR, and body fat percentage in both sexes. After adjusting for age, smoking status, alcohol drinking, regular exercise, medical comorbidities, monthly income, education level, and presence of depressive symptoms, the odds ratio (OR) of suicidal ideation was higher in elderly men with sarcopenia compared to those without, whereas no significant relationships were observed in elderly women (OR 8.28, 95% confidence interval [CI] 1.20–61.34 in men; OR 0.79, 95% CI 0.07–8.43 in women). Sarcopenia is closely associated with an increased risk of suicidal ideation in elderly men.     

Prevalence of overweight/obesity and its associated factors among a sample of Moroccan type 2 diabetes patients

BackgroundObesity constitutes a major risk factor for the development of diabetes, and has been linked with poor glycaemic control among type 2 diabetic patients.AimsThis study examines the prevalence of overweight/obesity and associated factors in type 2 diabetic patients in the Beni-Mellal Khenifra region in Morocco.MethodsA questionnaire-based cross-sectional study was conducted in 2017 among 975 diabetes patients attending primary health centres. Demographic and clinical data were collected through face-to-face interviews. Anthropometric measurements, including body weight, height and waist circumference, were taken using standardized techniques and calibrated equipment.ResultsThe prevalence of overweight was 40.4%, the general obesity was 28.8% and the abdominal obesity was 73.7%. Using multivariate analysis, we noted that the general obesity was associated with female sex (AOR= 3,004, 95% CI: 1.761–5.104, P<0.001), increased age (AOR=2.192, 95% CI: 1.116–4.307, P<0.023) and good glycaemic control (AOR=1.594, 95% CI: 1.056–2.407, P=0.027), whereas abdominal obesity was associated wih female sex (AOR=2.654, 95% CI: 1.507–4.671, P<0.001) and insulin treatment (AOR=2.927, 95% CI: 1.031–8.757, P=0.048).ConclusionOverweight, general obesity and abdominal obesity were high among participants, especially among women. Taken together, these findings urge the implementation of a roadmap for this diabetic subpopulation to have a new lifestyle.     

Prevalence of Childhood Obesity in the United States in 1999–2018: A 20-Year Analysis

IntroductionObesity is a public health crisis in the USA. This study aimed to estimate the prevalence of obesity and severe obesity in US children and adolescents and identify novel targetable risk factors associated with childhood obesity.MethodsFrom the US National Health and Nutrition Examination Survey from 1999 to 2018, 35,907 children aged 2–19 with body mass index (BMI) data were included. Obesity and severe obesity were defined as BMI ≥95th percentile and ≥120% of 95th percentile of US Centers for Disease Control and Prevention growth charts, respectively. Trends in the prevalence of obesity and subgroup analyses according to socioeconomic factors and language used in the interview were analyzed.ResultsThe prevalence of obesity and severe obesity increased from 14.7 [95% confidence interval: 12.9–17.0]% to 19.2 [17.2–21.0]% and 3.9 [2.9–5.0]% to 6.1 [4.8–8.0]% in 1999–2018, respectively (p = 0.001 and p = 0.014, respectively). In 2017–2018, the prevalence of obesity among children from Spanish-speaking households was 24.4 [22.4–27.0]%, higher than children from English-speaking households (p = 0.027).ConclusionThe prevalence of childhood obesity kept increasing in 1999–2018. The problem is worse in children from Spanish-speaking households. Novel and targeted public health intervention strategies are urgently warranted to effectively halt the rising epidemic of childhood obesity.     

Abdominal volume index: a predictive measure in relationship between depression/anxiety and obesity

BackgroundObesity is a risk factor for mood disorder (such as depression and anxiety). We aimed to assess application of A Body Shape Index (ABSI) and abdominal volume index (AVI), as new indices of obesity to evaluate the relationship between obesity and depression/anxiety.MethodsThis cross sectional study was conducted on 307 overweight and obese women (249 females, 58 males) 20–60 years in Iran in 2017–2018. The anthropometric measures including weight, waist circumference, hip circumference, body fat and derived values of body mass index, waist-hip ratio, AVI and ABSI were evaluated. HADS questionnaire for depression and anxiety completed.ResultsPrevalence of depression was 36.1% in women; men 24.1%; overweight 28.1%; obese 36.5 % and central obesity 33.7%. Anxiety was apparent in 27.1% of overweight 30.3 % obese and 29.6% central obesity. People with depression and anxiety had higher WC, BF and AVI. ABSI had no significant correlation with depression/anxiety. The odds of depression (1.06; 95% CI, 1.02–1.12) and anxiety (1.06; 95% CI, 1.01–1.11) were elevated with increase AVI.ConclusionOur results suggested that AVI as an indirect measure of abdominal obesity along with WC and BF could be useful in predicting the relationship between obesity and depression/anxiety.     

Systematic review with meta-analysis: Non-alcoholic fatty liver disease and the association with pregnancy outcomes

Background/AimsMaternal and fetal outcomes in pregnant patients with Non-alcoholic fatty liver disease (NAFLD) have been largely unexplored. To determine the level of evidence associated with maternal and fetal outcomes in pregnant women with NAFLD.MethodsWe conducted a comprehensive literature search. The studies included pregnant patients with a previous, current or subsequent diagnosis of NAFLD. We used a random-effects model using odds ratios (OR) with 95% confidence intervals (CI).ResultsTwenty-two studies, with 13,641 female NAFLD patients were reviewed. The results highlight that NAFLD patients had a statistically significant increased likelihood of baseline diabetes mellitus (OR, 6.00; 95% CI, 2.21–16.31; P<0.001; n=7), baseline Hypertension (OR, 3.75; 95% CI, 2.13–6.59; P<0.001; n=4), gestational hypertension (OR, 1.83; 95% CI, 1.03–3.26; P=0.041; n=2), and pre-eclampsia (OR, 2.43; 95% CI, 1.46–4.04; P=0.001; n=3). The odds for a past and current history of gestational diabetes mellitus were OR, 3.78; 95% CI, 2.21–6.44; P<0.001; n=5 and OR, 3.23; 95% CI, 1.97– 5.31; P<0.001; n=6, respectively. As for fetal outcomes, pregnant NAFLD patients were significantly more likely to have a premature birth (OR, 2.02; 95% CI, 1.44–2.85; P<0.001; n=4), large for gestational age birth (OR, 2.01; 95% CI, 1.72–2.37; P<0.001; n=2) or a history of prior miscarriage or abortion (OR, 1.15; 95% CI, 1.02–1.30; P=0.02; n=2). Egger’s regression revealed no evidence of publication bias (P>0.05).ConclusionsThis meta-analysis provides pooled evidence that NAFLD is associated with a substantial increase in maternal diabetic and hypertensive complications and multiple adverse fetal outcomes. This data is important for clinicians managing these patients before, during and after pregnancy.     

Weight Changes in Type 2 Diabetes and Cancer Risk: A Latent Class Trajectory Model Study

IntroductionBody mass index (BMI) is often elevated at type 2 diabetes (T2D) diagnosis. Using latent class trajectory modelling (LCTM) of BMI, we examined whether weight loss after diagnosis influenced cancer incidence and all-cause mortality.MethodsFrom 1995 to 2010, we identified 7,708 patients with T2D from the Salford Integrated Record database (UK) and linked to the cancer registry for information on obesity-related cancer (ORC), non-ORC; and all-cause mortality. Repeated BMIs were used to construct sex-specific latent class trajectories. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox regression models.ResultsFour sex-specific BMI classes were identified; stable-overweight, stable-obese, obese-slightly-decreasing, and obese-steeply-decreasing; comprising 41%, 45%, 13%, and 1% of women, and 45%, 37%, 17%, and 1% of men, respectively. In women, the stable-obese class had similar ORC risks as the obese-slightly-decreasing class, whereas the stable-overweight class had lower risks. In men, the obese-slightly-decreasing class had higher risks of ORC (HR = 1.86, 95% CI: 1.05–3.32) than the stable-obese class, while the stable-overweight class had similar risks No associations were observed for non-ORC. Compared to the stable-obese class, women (HR = 1.60, 95% CI: 0.99–2.58) and men (HR = 2.37, 95% CI: 1.66–3.39) in the obese-slightly-decreasing class had elevated mortality. No associations were observed for the stable-overweight classes.ConclusionPatients who lost weight after T2D diagnosis had higher risks for ORC (in men) and higher all-cause mortality (both genders) than patients with stable obesity.     

Association of Physical Activity and Sitting Time with Overweight/Obesity in Chinese Occupational Populations

AbstractThe aim of this study was to explore association of physical activity and sitting time with overweight/obesity in Chinese occupational populations for the development of intervention and prevention strategies for obesity.MethodsA total of 23,112 participants were selected from the 2010–2012 China National Nutrition and Health Survey (CNNHS). A logistics regression model was used to examine the associations of physical activity and sitting time with overweight/obesity by gender after adjusting for age, educational level, marital status, and family economic level.ResultsThe prevalence of overweight/obesity based on the WHO definition and the WGOC definition was 30.8% and 41.3%, respectively. Male employees with moderate and heavy occupation activity intensity had a lower risk for overweight/obesity than those with light occupation activity intensity (moderate: OR 0.90, 95% CI 0.82–0.98; heavy: OR 0.75, 95% CI 0.65–0.86), and the risk of overweight/obesity of male employees with long work-time spent sitting was higher than those with short work-time spent sitting (2–4.9 h/day: OR 1.26, 95% CI 1.14–1.40; ≥5 h/day: OR 1.29, 95% CI 1.15–1.44). The risk of overweight/obesity of male employees with active transportation mode was lower than those with inactive transportation mode (OR 0.91, 95% CI 0.84–0.99), while the risk of overweight/obesity of female employees with active transportation mode was higher (OR 1.14, 95% CI 1.04–1.25). Female employees with leisure-time physical activity (LTPA) for ≥150 min/week had lower risk of overweight/obesity than those with LTPA for <150 min/week (OR 0.69, 95% CI 0.56–0.84). There was no significant association of leisure-time sitting and housework time with overweight/obesity in Chinese occupational populations.ConclusionOccupation activity intensity, LTPA, transportation mode, and work sitting time were associated with overweight/obesity. Reducing work sitting time, moderate and heavy occupation activity intensity, and an active transportation mode could help male employees decrease the risk of overweight/obesity. Increasing leisure-time physical activity could reduce the risk of overweight/obesity in women. Our findings provided insight into the association of physical activity and sitting time with overweight/obesity. It will be necessary to carry out workplace-based interventions, have an active transportation mode, and increase leisure-time physical activity to decrease the risks of overweight/obesity.     

Interactions between Prepregnancy Overweight and Passive Smoking for Macrosomia and Large for Gestational Age in Chinese Pregnant Women

IntroductionPrevious analysis showed that passive smoking and overweight were associated with an increased risk of gestational diabetes mellitus (GDM) in a synergistic manner, while GDM increased the risk of macrosomia/large for gestational age (LGA). This study aimed to examine any interactive effects between passive smoking and overweight/obesity on risk of macrosomia/LGA.MethodsFrom 2010 to 2012, 22,302 pregnant women registered for pregnancy at a primary hospital in Tianjin, China. Data were collected longitudinally; that is, from their first antenatal care visit, at the glucose challenge test (GCT) time (24–28 weeks of gestation) and at delivery. Passive smoking was self-reported. Macrosomia was defined as birth weight ≥4,000 g. Binary logistic regression was used to obtain odds ratios (ORs) and 95% confidence intervals (CIs). Additive interaction was used to test the synergistic effect.ResultsPassive smokers accounted for 57.4% of women (n = 8,230). Using nonpassive smoking and prepregnancy body mass index (BMI) <24.0 kg/m² as the reference, the adjusted ORs of overweight alone and passive smoking alone for macrosomia were 2.39 (95% CI: 2.11–2.71) and 1.17 (95% CI: 1.04–1.32). Copresence of passive smoking and prepregnancy BMI ≥24.0 kg/m² increased the OR to 2.70 (95% CI: 2.28–3.20), with a significant additive interaction. After further adjustment for GDM or GCT, the OR of copresence of both risk factors was slightly attenuated to 2.52 (2.13–3.00) and 2.51 (2.11–2.98), with significant additive interaction. However, the additive interaction between prepregnancy overweight/obesity and passive smoking for LGA was nonsignificant.ConclusionsPrepregnancy overweight/obesity was associated with an increased risk of macrosomia in Chinese women synergistically with passive smoking during pregnancy, and most of the association was not modified by hyperglycemia during pregnancy.     

On the way to universal coverage of maternal services in Iringa rural District in Tanzania. Who is yet to be reached?

BackgroundStrategies to tackle maternal mortality in sub-Saharan Africa include expanding coverage of reproductive services. Even where high, more vulnerable women may not access services. No data is available on high coverage determinants. We investigated this in Tanzania in a predicted high utilization area.MethodsData was collected through a household survey of 464 women with a recent delivery. Primary outcomes were facility delivery and ≥4 ANC visits. Determinants were analysed using multivariate regression.ResultsAlmost all women had attended ANC, though only 58.3% had ≥4 visits. ≥4 visits were more likely in the youngest age group (OR 2.7 95% CI 1.32–5.49, p=0.008), and in early ANC attenders (OR 3.2 95% CI 2.04–4.90, p<0.001). Facility delivery was greater than expected (87.7%), more likely in more educated women (OR 2.7 95% CI 1.50–4.75, p=0.002), in those within 5 kilometers of a facility (OR 3.2 95% CI 1.59–6.48, p=0.002), and for early ANC attenders (OR 2.4 95% CI 1.20–4.91, p=0.02).ConclusionRural contexts can achieve high facility delivery coverage. Based on our findings, strategies to reach women yet unserved should include promotion of early ANC start particularly for the less educated, and improvement of distant communities'' access to facilities.     

Meta-Analysis of the Relationship between Abdominal Obesity and Diabetic Kidney Disease in Type 2 Diabetic Patients

Background and ObjectivesThe meta-analysis aimed to investigate the association of visceral fat area (VFA), waist circumference (WC), waist-hip ratio (WHR) and waist-height ratio (WHtR) with diabetic kidney disease (DKD) in type 2 diabetic patients.MethodsIncluded studies were searched from Pubmed, Embase, and the Cochrane Library before July 2020. We synthesized the pooled results of the above relationships by meta-analysis.ResultsFourteen cross-sectional studies were enrolled. The pooled results indicated there was a significant difference in continuous VFA, WC and WHR/WHtR between patients with DKD and those without DKD (standard mean difference, SMD, 0.24, 95% confidence interval, CI, 0.13–0.36, p = 0.000). For VFA, patients with DKD had higher VFA levels than those without DKD (SMD 0.27, 95% CI 0.03–0.50). In the WC subgroup, patients with DKD had higher WC levels than those without DKD (SMD 0.17, 95% CI 0.10–0.24); similarly, abdominal obesity (dichotomized WC) was significantly associated with an increase in the odds of DKD (expected shortfall, ES, 1.57, 95% CI 1.32–1.86). However, the association of continuous WHR/WHtR with DKD was not statistically significant (SMD 0.43, 95% CI −0.12 to 0.97), while we found this relationship was statistically significant when analyzed categorically (ES 1.58, 95% CI 1.22–2.06).ConclusionIn this meta-analysis, we found abdominal obesity parameters (continuous VFA, WC) were associated with increased odds of DKD, and type 2 diabetic patients with DKD were more likely to have abdominal obesity (categorized using WC or WHR/WHtR).     

Risk of Pregnancy Complications and Low Birth Weight Offsprings in Korean Women With Rheumatic Diseases: A Nationwide Population-Based Study

BackgroundTo determine the risk of pregnancy complications and adverse offspring outcomes in Korean women with rheumatic diseases (RDs).MethodsWomen aged 20–44 years with pregnancies ending in delivery were identified from the National Health Insurance Service-National Health Information Database (2009–2016). Women with RD including systemic lupus erythematosus (SLE), seropositive rheumatoid arthritis (SPRA), and ankylosing spondylitis (AS) (n = 4,284) were age-matched with controls (n = 26,023). Outcome variables included threatened abortion (TA), preterm birth (PB), preeclampsia/eclampsia (PE/E), intrauterine growth retardation (IGR), urinary tract infection, low birth weight (LBW) offsprings, and offspring death within 1 year of birth.ResultsWomen with RDs had increased risks for cesarean section delivery (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.4–1.6), TA (OR, 1.4; 95% CI, 1.2–1.5), PB (OR, 2.4; 95% CI, 1.9–3.2), PE/E (OR, 4.4; 95% CI, 3.3–5.9), and IGR (OR, 2.4; 95% CI, 2.0–3.1) than the controls. The risk of pregnancy complications was increased in SLE and SPRA pregnancies but not in AS pregnancies. Offsprings of women with RDs had an increased risk of LBW (OR, 4.0; 95% CI, 3.2–4.9). The offspring mortality rate within 1 year of birth was higher in women with RDs (6.2/10,000 persons) than in the controls (4.9/10,000 persons).ConclusionWomen with RDs are at a risk of developing pregnancy complications, and the risk of LBW offsprings and offspring death within 1 year of birth is increased in these women. Therefore, this population requires special attention during their childbearing years.     

Insomnia with objective short sleep duration is associated with cognitive impairment: a first look at cardiometabolic contributors to brain health

Study ObjectivesInsomnia with objective short sleep duration has been previously associated with adverse cardiometabolic health outcomes as well as poorer cognitive performance in otherwise noncognitively impaired adults. However, studies demonstrating an increased prevalence of cognitive impairment (CI) in this insomnia phenotype are lacking.MethodsWe analyzed data from Penn State Adult Cohort (N = 1,524; 48.9 ± 13.4 years; 53.4% women). Self-reported sleep difficulty was defined as normal sleep (n = 899), poor sleep (n = 453), and chronic insomnia (n = 172). Objective short sleep duration was defined as less than 6-h of sleep, based on in-lab, 8-h polysomnography. CI (n = 155) and possible vascular cognitive impairment (pVCI, n = 122) were ascertained using a comprehensive neuropsychological battery. Analyses adjusted for age, sex, race, education, body mass index, apnea/hypopnea index, smoking, alcohol, psychoactive medication, and mental and physical health problems.ResultsParticipants who reported poor sleep or chronic insomnia and slept objectively less than 6 hours were associated with a 2-fold increased odds of CI (OR = 2.06, 95% confidence limits [CL] = 1.15–3.66 and OR = 2.18, 95% CL = 1.07–4.47, respectively) and of pVCI (OR = 1.94, 95% CL = 1.01–3.75 and OR = 2.33, 95% CL = 1.07–5.06, respectively). Participants who reported poor sleep or chronic insomnia and slept objectively more than 6 hours were not associated with increased odds of either CI (OR = 0.72, 95% CL = 0.30–1.76 and OR = 0.75, 95% CL = 0.21–2.71, respectively) or pVCI (OR = 1.08, 95% CL = 0.42–2.74 and OR = 0.76, 95% CL = 0.16–3.57, respectively).ConclusionsInsomnia with objective short sleep duration is associated with an increased prevalence of CI, particularly as it relates to cardiometabolic health (i.e. pVCI). These data further support that this insomnia phenotype may be a more biologically severe form of the disorder associated with cardiovascular, cerebrovascular, and neurocognitive morbidity.     

Association of upper trunk and visceral adipose tissue volume with insulin resistance in control and HIV-infected subjects in the FRAM study

Visceral obesity is associated with insulin resistance, but the association of other regional adipose depots with insulin resistance is not understood. In HIV infection, buffalo hump (upper trunk fat) is associated, but the association of upper trunk fat with insulin resistance has not been examined in controls. To determine the independent association of adipose depots other than visceral with insulin resistance, we performed a cross-sectional analysis of controls and HIV-infected subjects in the Fat Redistribution and Metabolic Change in HIV Infection (FRAM) study, who had measurements of glucose, insulin, and adipose tissue volumes by whole-body magnetic resonance imaging. We studied 926 HIV-positive persons from 16 academic medical center clinics and trials units with demographic characteristics representative of US patients with HIV infection and 258 FRAM controls from the population-based Coronary Artery Risk Development in Young Adults study. We measured visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) volume in the legs, arms, lower trunk (back and abdomen), and upper trunk (back and chest) and assessed their association with the homeostasis model of assessment (HOMA) and HOMA >4 by stepwise multivariable analysis. The prevalence of HOMA >4 as a marker of insulin resistance was 28% among controls compared with 37% among HIV-infected subjects (P = 0.005). Among controls, those in the highest tertile of upper trunk SAT volume had an odds ratio (OR) of 9.0 (95% confidence interval [CI]: 2.4 to 34; P = 0.001) for having HOMA >4 compared with the lowest tertile, whereas in HIV-positive subjects, the OR was lower (OR = 2.09, 95% CI: 1.36 to 3.19; P = 0.001). Among controls, the highest tertile of VAT volume had an OR of 12.1 (95% CI: 3.2 to 46; P = 0.0002) of having HOMA >4 compared with the lowest tertile, whereas in HIV-positive subjects, the OR was 3.12 (95% CI: 2.0 to 4.8; P < 0.0001). After adjusting for VAT and upper trunk SAT, the association of other SAT depots with HOMA >4 did not reach statistical significance. Thus, VAT and upper trunk SAT are independently associated with insulin resistance in controls and in HIV-infected persons.     

Maternal and neonatal outcomes of grand multiparity in Khartoum,Sudan

ObjectivesGrand multiparity is a major health problem that leads to adverse maternal and perinatal outcomes. We aimed to assess the maternal and perinatal outcomes of grand multiparity.MethodsA case-control study was conducted in Saad Abualila Hospital, Khartoum, Sudan from February to December 2019. The cases were grand multiparous (≥ 5 deliveries) women. The controls were women with low parity (multiparous women who delivered two to four times). Maternal and perinatal characteristics were compared between the two groups. Logistic regression analysis was performed.ResultsThere was a significant association between grand multiparity and higher maternal age (adjusted odds ratio [AOR]=1.19, 95% confidence interval [CI]=1.16–1.23), lower education level (AOR=3.38, 95% CI=2.49–5.58) and lower antenatal care attendance (AOR=1.73, 95% CI=1.02–2.92). Grand multiparous women were at increased risk for Anemia (AOR=1.48, 95% CI=1.08–2.03), diabetes mellitus (AOR=10.61, 95% CI=4.89–23.00), caesarean delivery (AOR=1.87, 95% CI=1.40–2.48), preterm birth (AOR=1.90, 95% CI=1.37–2.62) and admission to the neonatal intensive care unit (AOR=3.8, 95% CI=1.95–7.75).ConclusionsGrand multiparity was associated with poor maternal and neonatal outcomes. Development of a national health program addressing family planning, health education and improvement of antenatal, intrapartum and neonatal care are needed.     

Association between Obesity and Chronic Laryngitis in Women – Data from the Korea National Health and Nutrition Examination Survey

BackgroundThis study aimed to investigate the relationship between obesity and chronic laryngitis in South Korea using data from the Korea National Health and Nutrition Examination Surveys (KNHANES) collected during 2008-2010.MethodsKNHANES was a cross-sectional survey of the civilian, non-institutionalized population of South Korea (n = 13,819). Obesity status was measured by using BMI and waist circumference.ResultsAmong the population over 19 years of age, the prevalence of chronic laryngitis was 4.0 ± 0.4%. Chronic laryngitis was significantly associated with age, BMI, waist circumference, fat proportion, both systolic and diastolic blood pressure, fasting blood sugar, triglycerides, and high-density lipoprotein cholesterol in women. Old age and current smoking were significantly associated with chronic laryngitis in men. Obese women were at a higher risk for chronic laryngitis than women without obesity (odds ratio (OR) 2.022, 95% confidence interval (95% CI) 1.412-2.895) after further adjustment for confounders. Women with abdominal obesity were also at higher risk for chronic laryngitis (OR 1.475, 95% CI 1.024-2.126).ConclusionObese women in Korea have an elevated risk for developing chronic laryngitis. Further epidemiological and experimental studies are necessary to clarify the impact of obesity on this condition.Key Words: Laryngitis, Obesity, Epidemiology     

A gender comparison of psychological distress among medical students in Nigeria during the Coronavirus pandemic: a cross-sectional survey

BackgroundThe Coronavirus disease (COVID-19) pandemic as a large scale stressor could have negative effects on the mental health of medical students. Since gender differences in mental health may exist, it is important to see if a large scale stressor like the pandemic may be associated with variances in the psychological distress between both genders.ObjectivesTo assess and compare the psychological distress of male and female medical students during the COVID-19 pandemic.MethodsA cross-sectional survey was carried out among 1010 medical students from three universities in southwestern Nigeria within the first six months of the first reported case of the COVID-19 pandemic. The respondents were purposively selected. Data was obtained online on participants'' demographic and psychological distress using the General Health Questionnaire 12 (GHQ-12). Data was analyzed using the SPSS version 21, student t and chi-square tests were used to assess gender differences, and multivariate regression to assess the predictors of psychological distress among both genders. p values less than 0.05were considered statistically significant.ResultsOverall, female participants (OR=1.455, 95% CI= 1.095–1.936) were twice more likely to have experienced psychological distress than males during the COVID-19 pandemic. Age (OR=0.922, 95% CI= 0.867–0.979), being in pre-clinical years (OR= 1.394, 95% CI= 1.004–1.938), having a family income less than 100,000 naira (OR= 1.379, 95% CI=1.442–6.723) a previous history of mental illness (OR=3.077, 95% CI= 1.430–6.615) and having a relative/acquaintance diagnosed with COVID 19(OR=1.646, 95% CI= 1.062–2.551) were independently associated with psychological distress among the respondents. When comparing both genders, among females, age (OR=0.886, 95% CI= 0.803–0.978), family income less than 100,000 naira (OR=1.898, 95% CI= 1.306–2.759) and a previous history of mental illness (OR=5.266, 95% CI= 1.894–14.635) were associated with psychological distress, while, being in pre-clinical years (OR= 1.713, 95% CI= 1.052–2.790) was associated with psychological distress among males.ConclusionFemales had more psychological distress compared to male students. It is recommended that gender-specific interventions addressing psychological distress among medical students are instituted.     

Gender Differences in Comorbidities and Attitudes Regarding Weight Control among Young Adults with Obesity in Korea

IntroductionObesity in young adulthood increases the risk for premature death, and the prevalence of obesity rapidly increasing among young adults, particularly in young men. We evaluated the gender differences in accompanying comorbidities and attitudes regarding weight control among young Korean adults with obesity.Materials and MethodsWe analyzed 2,050 young adults with obesity (1,325 men and 725 women) in the 7th KNHANES (2016–2018) aged 19–44 years, with body mass indexes (BMIs) ≥25.0 kg/m². The odds ratios (ORs) and 95% confidence intervals (CIs) for poor lifestyle factors and accompanying illnesses as well as self-perceived weight status, weight control efforts, and weight control strategies in men compared to those in women were calculated by multivariate logistic regression analysis.ResultsThe mean BMIs and waist circumferences were 28.2 ± 0.1 kg/m² and 93.6 ± 0.2 cm and 28.6 ± 0.1 kg/m² and 88.7 ± 0.4 cm, in men and women, respectively. The ORs and 95% CIs for abdominal obesity (1.52, 1.11–2.07), hypertension (3.11, 2.20–4.40), hypercholesterolemia (1.45, 1.09–1.93), hypertriglyceridemia (3.37, 2.38–4.78), and elevated alanine transaminase concentration (6.53, 4.56–9.36) were higher in young men compared to those in young women. Despite the higher prevalences of comorbid conditions, the odds of inappropriate weight perception (8.13, 4.17–15.86), lack of weight control efforts (2.20, 1.71–2.84), lack of diet therapy (1.56, 1.13–2.16), lack of pharmacotherapy (13.27, 6.82–25.79), heavy drinking (1.32, 1.02–1.72), current smoking (6.92, 5.00–9.59), and frequent eating out (4.38, 3.35–5.71) were higher among men. However, the odds of not engaging in exercise (0.48, 0.35–0.64) were lower among men compared to that in women.DiscussionDespite their higher prevalences of comorbidities, appropriate weight perception and weight control efforts are insufficient in young men with obesity. These gender differences should be considered to provide tailored programs for weight reduction in young adults with obesity.     

Cerebrovascular accidents differ between patients with atrial flutter and patients with atrial fibrillation

IntroductionFew studies have explored the potential impact of atrial flutter (AFl) on ischaemic stroke (IS) outcome. The aim of the present study was to compare the clinical course of IS in patients with AFl and patients with atrial fibrillation (AF).Material and methodsA retrospective analysis of patients consecutively admitted to a tertiary care centre between 2013 and 2015 due to IS or transient ischaemic attack with permanent AFl or permanent or persistent AF was performed.ResultsThe study groups consisted of 528 patients, including 490 (92.8%) patients with AF and 38 (7.2%) patients with AFl. The mean age and prestroke CHA2DS2-VASc scores were similar between the patients with AFl and those with AF. Most IS cases in the AF group were classified as cardioembolic strokes (74.9% vs. 39.5% in AFl, p < 0.01), and lacunar strokes were the most common in the AFl group (47.4% vs. 14.3% in AF, p < 0.01). The multivariable analysis revealed that the presence of AF (OR = 8.6, 95% CI: 1.2–57, p = 0.02), lacunar stroke (OR = 0.1, 95% CI: 0.03–0.31, p < 0.001), baseline Rankin scale score (OR = 16.6, 95% CI: 9.8–28), lack of prestroke therapeutic anticoagulation (OR = 6.1, 95% CI: 1.1–33), diabetes (OR = 2.9, 95% CI: 1.3–6.5, p < 0.01), chronic heart failure (OR = 14.2, 95% CI: 5.8–34, p < 0.001), and current smoking (OR = 0.92, 95% CI: 0.39–0.99, p < 0.01) were significantly associated with the stroke outcome.ConclusionsDisabling or fatal IS was observed less often in patients with AFl than in patients with AF. This finding can possibly be explained by the more frequent occurrence of lacunar strokes in the AFl group compared with that in the AF group.     

Relationship between Sarcopenic Obesity and Cardiovascular Disease Risk as Estimated by the Framingham Risk Score

This study was conducted to assess the association between sarcopenic obesity and cardiovascular disease (CVD) risk in Korean adults (n=3,320; ≥40 yr) who participated in the 5th Korean National Health and Nutrition Examination Survey in 2010. The appendicular skeletal muscle mass divided by body weight was calculated for each participant; participants with values <1 standard deviation below the mean reference value (i.e., aged 20-39 yr) were considered sarcopenic. Subjects were further classified into 4 groups according to their obesity (i.e., body mass index ≥25 kg/m²) and sarcopenic status. Individuals'' 10-yr CVD risk was determined using the Framingham risk model. The sarcopenic obese group had more participants (43.8% men, 14.6% women) with a high risk of CVD (≥20%). The sarcopenic obese group was associated with an increased 10-yr CVD risk than the non-sarcopenic, non-obese group (odds ratio [OR], 2.49; 95% confidence interval [CI], 1.53-4.06, P<0.001 in men; OR, 1.87; 95% CI, 1.02-3.41, P=0.041 in women). Sarcopenic non-obese and non-sarcopenic obese subjects were not associated with an increased 10-yr CVD risk. Sarcopenic obesity, but not non-sarcopenic obesity, was closely associated with an increased CVD risk in Korean adults.
