Abstract Background Previous studies have revealed that current secondhand smoke exposure showed highly suggestive evidence for increased risk of simultaneous sleep problems in children. Data on the associations between early-life exposure to SHS with subsequent sleep problems in children were scarce. We aimed to evaluate the associations of early-life SHS exposure with sleep problems in children. Methods In this cross-sectional study, children were recruited from elementary and middle schools in Liaoning Province, China between April 2012 and January 2013. We assessed early-life SHS exposure (pregnancy and the first 2 years of life) via questionnaires. Sleep problems and different types of sleep-related symptoms were measured based on the validated tool of the Sleep Disturbance Scale for Children (SDSC). Generalized linear mixed models were applied to estimate the associations of early-life SHS exposure with sleep problems. Results We included a total of 45,562 children (22,657 [49.7%] males; mean [SD] age, 11.0 [2.6] years) and 6167 of them (13.5%) were exposed to early-life SHS during both pregnancy and the first 2 years of life. Compared with unexposed counterparts, children exposed to early-life SHS had higher total T-scores of SDSC (β = 4.32; 95%CI: 4.06, 4.58) and higher odds of increased sleep problems (OR = 2.14; 95%CI: 1.89, 2.42). When considering different sleep-related symptoms, the associations between early-life SHS exposure and symptom of sleep-wake transition disorders (i.e., bruxism) were the strongest in all analyses. Conclusions Early-life SHS exposure was associated with higher odds of global sleep problems and different sleep-related symptoms in children aged 6–18 years. Our findings highlight the importance to strengthen efforts to support the critical importance of maintaining a smoke-free environment especially in early life.

Despite the advancement of the healthcare system, low birth weight (LBW) remains as one of the leading causes of under-five mortality. This cross-sectional study aimed to determine the prevalence of LBW and its associated factors among 483 third trimester pregnant women recruited from six selected public health clinics in the Federal Territory of Kuala Lumpur and the state of Selangor, Malaysia. Pregnant women were interviewed for information on socio-demographic characteristics, smoking behaviour, and second-hand smoke (SHS) exposure at home and in the workplace. Information on the obstetrical history and prenatal care visits history were retrieved from the maternal medical records, while infant’s birth outcomes were retrieved from infant medical records. The prevalence of LBW (<2.5 kg) in infants was 10.4%, with a mean birth weight of 3.0 [standard deviation (SD) 0.4] kg. Results from the multivariable logistic regression model showed that inadequate weight gained during pregnancy [odds ratio (OR) = 2.41, 95% confidence interval (CI) = 1.18–4.90] and exposure to SHS at home (OR = 1.92, 95% CI = 1.03–3.55) were significantly associated with LBW. In conclusion, pregnant women should monitor their rate of weight gain throughout pregnancy and avoid SHS exposure at home to reduce the risk of delivering LBW infants.

Second Hand Smoking

Exposure to second-hand smoke (SHS) among non-smoking pregnant women can lead to adverse maternal and fetal outcomes. A cross-sectional study was performed from July to August 2016 among 432 pregnant women at Bach Mai Hospital, Hanoi, Vietnam, to assess the prevalence and sources of SHS exposure among non-smoking pregnant women. Socio-economic characteristics and information regarding SHS exposure of participants were collected. Multivariable logistic regression was employed to identify associated factors. Overall, 92.6% and 64.5% of pregnant women were exposed to SHS in their lifetime and in the last 30 days, respectively. Cafeterias and restaurants had the highest proportion of pregnant women exposed to SHS. Those who reported that “smoking is allowed at home” (OR = 3.18; 95%CI = 1.97–5.13); going to working place (OR = 1.86; 95%CI = 1.08–3.19), going to state authority offices (OR = 1.98; 95%CI = 1.15–3.41), and cafeterias (OR = 1.96; 95%CI = 1.22–3.16) had the highest risk of SHS exposure in the last 30 days. We have found a high proportion of SHS exposure among non-smoking pregnant women in Vietnam. This comes from a multitude of sources, including homes, workplaces, cafeterias, and restaurants. The data emphasises the need for further intervention to address this health issue.

Abstract Background: The hypertriglyceridemic waist (HTGW) phenotype has been suggested as a risk factor for chronic kidney disease (CKD), but evidence on relationship of triglyceride waist phenotypes with estimated glomerular filtration rate (eGFR) status and severity is limited. Our aim was to explore the association of triglyceride waist phenotypes with reduced eGFR and various decreased eGFR stages among Chinese adults.Methods: A population-based, cross-sectional study was conducted among Chinese participants aged 20-74 years during June 2016 to December 2017 in Shanghai, China. An eGFR value below 60 mL/min/1.73 m2 was defined as Decreased eGFR. The HTGW phenotype was defined as a triglycerides (TG) level ≥1.7 mmol/L and a waist circumference (WC) ≥90 cm for men and ≥80 cm for women. We examined the association of triglyceride waist phenotypes with decreased eGFR risk using the weighted logistic regression models.Results: A total of 31,296 adults were included in this study. Compared with normal TG level/normal WC (NTNW) phenotype, normal TG level/enlarged WC (NTGW), elevated TG level/normal WC (HTNW), elevated TG level/enlarged WC (HTGW) were associated with the increased risk of decreased eGFR, with an multivariable-adjusted ORs (95% CI) of 1.77 (1.42-2.20), 1.48 (1.16-1.90), and 2.30 (1.80-2.93), respectively. These positive associations between triglyceride waist phenotypes and decreased eGFR risk remained across almost all the subgroups, including sex, age, BMI, T2DM, and hypertension. NTGW, HTNW, and HTGW phenotype were consistently positively associated with the risk of mildly and moderately decreased eGFR, but not with severely decreased eGFR risk.Conclusions: HTGW was consistently associated with the increased risk of decreased eGFR and various decreased eGFR stages except for severely decreased eGFR. The findings imply that HTGW may be an important risk factor for renal dysfunction or an indicator for prevention and control aiming to reduce renal function decline.

Abstract Focus of Presentation Tobacco has always been a major public health issue. Being tobacco a major risk factor for so many diseases, it has also become a matter of concern in current situation of the pandemic. Tobacco smoking is not only harmful for the person who is actively smoking but also to ones who are in the vicinity of that smoke. There is plenty of evidence regarding harmful effects of both tobacco and inhaling tobacco smoke passively. This passive smoke is known as Second Hand Smoke. The aim of the study was to estimate percentage and sources of Second Hand Smoke exposure among pregnant women. It was a cross sectional study conducted among pregnant women registered at a Primary health centre. Findings Out of total participants, 62% were exposed to Second hand smoke. 33% participants were exposed to SHS at home only, 24% at public places only and 5 % were the one exposed both at home and public places. More than half (69%) of the participants were having inadequate knowledge about the harms caused by Second hand smoke Conclusions/Implications More than half of the participants were exposed to Second hand smoke. Inadequate knowledge among the participants about adverse effects of SHS exposure and insufficient Key messages Smoke-free homes should be promoted and health-care providers should ask pregnant women about their exposure to SHS and inform about the harms of SHS exposure during anti natal visits.

Abstract Anemia is a global public health problem affecting women worldwide, and reproductive-age women are at increased risk. We conducted a population-based cross-sectional study analyzing the prevalence of overall anemia and anemia according to severity in Chinese pre-pregnant women to update current knowledge on anemia epidemiology. Based on the National Free Preconception Check-up Projects supported by the Chinese government, 5,679,782 women participating in this project in 2017 were included in this study. The cyanmethemoglobin method was applied to assess hemoglobin concentrations. Univariate and multivariate logistic regressions were applied for associated factors. The prevalence of anemia among Chinese pre-pregnant women was 21.64% (mild anemia: 14.10%, moderate anemia: 7.17%, severe anemia: 0.37%). The prevalence of overall and severe anemia was the highest in Tibet and the lowest in Beijing among 31 provinces. Women’s age, region, ethnic origin, educational level, occupation, and pregnancy history were all correlated with anemia. Women with B blood type (aOR=0.89), higher BMIs (overweight: aOR=0.84; obesity: aOR=0.70), and alcohol consumption (aOR=0.69) were less likely to have anemia, while those with rhesus negative blood type (aOR=1.10), history of anemia (aOR=2.60), older age at menarche (aOR=1.19), heavy menstrual blood loss (aOR=1.39), longer menstrual period (aOR=1.09) and shorter menstrual cycle (aOR=1.08) were more likely to suffer from anemia. Meat or egg eaters were not significantly associated with severe anemia. Anemia is of moderate public health significance among Chinese pre-pregnant women. Interventions should be considered to prevent anemia to the greatest extent possible to avoid potential harm in this population.

AbstractAssociation of lifestyle-related factors and mental health has been less studied in Middle Eastern countries. This study aimed to examine the prevalence of two common mental health problems, i.e., depression and anxiety, and their lifestyle determinants in a large sample of Iranian population.This study was conducted within the framework of SEPAHAN population based cross-sectional study (N=4763(. The General Practice Physical Activity Questionnaire (GPPAQ) was used to assess physical activity and the Iranian-validated version of Hospital Anxiety and Depression Scale (HADS) was applied to screen for anxiety and depression. Logistic regression was used as the main statistical method for data analysis by SPSS version 16.0. A P-value <0.05 was considered to be statistically significant.The risk of anxiety and depression was 2.5 (OR=2.56,95% CI: 1.97-3.33) and 2.21(1.83-2.67) times higher in women than men, respectively. With every one-year increase in the age, the risk of anxiety decreased by 2% (OR=0.98,95% CI:0.97-0.99). Individuals with higher education had 56% lower risk of anxiety (OR=0.44,95% CI: 0.36-0.55) and 46% depression (OR=0.54,95% CI: 0.46-0.64) than the undergraduate group, and the risk of depression in the inactive (less than one hour of activity per week) group was 27% higher than the active group (OR=1.27,95% CI: 1.06-1.51). The risk of anxiety in the non-smoker group was 65% (OR=0.35,95% CI: 0.20-0.59) and depression was 64% lower than among smokers (OR=0.34,95% CI:0.22-0.53). In the ex-smoker group, the risk of anxiety was 60% (OR=0.40,95% CI:0.19-0.85) and depression was 59% lower than for the smoker group (OR=0.41,95% CI: 0.24-0.73).This current study’s results demonstrated significant associations between unhealthy lifestyle factors and increased risk of anxiety and depression. Hence, special attention must be paid to preventive intervention programmes aiming to enhance healthy lifestyle among at-risk populations.

ObjectiveTo determine the predictors of non-fatal violence or assault among adolescents in rural Bangladesh to inform evidence-based interventions.DesignCross-sectional study.SettingHousehold survey and national census in 51 unions of rural Bangladesh.Participants, methods and main outcome213 782 adolescents aged 11–19 years who reported violence during a population-based survey in 2013. We used logistic regression to determine the prevalence of factors that predict non-fatal forms of violence or assaults among adolescents. Assault or violence was defined as all injuries inflicted directly by another person or resulting from collateral impact over a 6-month recall period.Results457 (0.21%) cases of violence or assault were reported. The adjusted prevalence ratio (PR) of violence was lower among female adolescents compared with males (PR: 0.60, 95% CI 0.47 to 0.78, p<0.001). Compared with the lowest socioeconomic quintile, being in a higher quintile was associated with lower prevalence of violence, with a 39% decrease in the adjusted prevalence of violence among adolescents in highest compared with lowest socioeconomic index (PR: 0.61, 95% CI 0.44 to 0.84). The adjusted prevalence of violence in Chandpur and Comilla districts was 7.30 times and 7.27 times higher respectively than the prevalence of violence in Sirajganj (PR: 7.30, 95% CI 4.07 to 13.10 and PR: 7.27, 95% CI 3.56 to 14.84, respectively). There was no significant difference in the adjusted prevalence of violence occurring in school compared with home (PR: 1.19, 95% CI 0.85 to 1.69).ConclusionMale adolescents may be at an increased risk of suffering violence, and socioeconomic factors and place (districts) are strong predictors of adolescent violence among a selected population in rural Bangladesh. These findings are important in guiding interventions to address the burden of violence among adolescents in communities with similar demographics as our study population. Further research is needed to identify the actual burden of violence among adolescents at national level and to establish an effective violence prevention programme across Bangladesh.
