ObjectivesTo report the situation of maternal micronutrient supplementation before and during pregnancy in Northwest China and to examine the rates of and factors related to the adherence to micronutrient supplementation among pregnant women in this region, where dietary micronutrient intake is commonly insufficient.DesignA large-scale population-based cross-sectional survey.SettingTwenty counties and ten districts of Shaanxi Province.ParticipantsA sample of 30 027 women were selected using a stratified multistage random sampling method. A total of 28 678 women were chosen for the final analysis after excluding those who did not provide clear information about nutritional supplementation before and during pregnancy.Main outcome measuresMaternal adherence to micronutrient supplementation (high and low) were the outcomes. They were determined by the start time and duration of use according to Chinese guidelines (for folic acid (FA) supplements) and WHO recommendations (for iron, calcium and multiple-micronutrient (MMN) supplements).ResultsIn total, 83.9% of women took at least one kind of micronutrient supplement before or during pregnancy. FA (67.6%) and calcium (57.5%) were the primarily used micronutrient supplements; few participants used MMN (14.0%) or iron (5.4%). Adherence to supplementation of all micronutrients was low (7.4% for FA, 0.6% for iron, 11.7% for calcium and 2.7% for MMN). Higher educational levels, higher income levels, urban residence and better antenatal care (including pregnancy consultation and a higher frequency of antenatal visits) were associated with high adherence to micronutrient supplementation.ConclusionMaternal micronutrient supplementation before and during pregnancy in Northwest China was way below standards recommended by the Chinese guidelines or WHO. Targeted health education and future nutritional guidelines are suggested to improve this situation, especially in pregnant women with disadvantaged sociodemographic conditions.

AbstractObjective:To investigate the association of folic acid (FA) supplementation with birth weight, the risk of small for gestational age (SGA) and low birth weight (LBW) in singleton and twin pregnancy.Design:A population-based cross-sectional survey.Setting:Twenty counties and ten districts in Shaanxi Province of northwestern China, 2013.Participants:28 174 pregnant women with their infants, covering 27 818 single live births and 356 twin live births.Results:The prevalence of FA supplementation in singletons and twins was 63·9 and 66·3 %. The mean birth weight was 3267 (sd 459·1) g, 2525 (sd 534·0) g and 2494 (sd 539·5) g; the prevalence of SGA was 14·3, 51·4 and 53·4 %; the prevalence of LBW was 3·4, 42·4 and 46·6 % among singleton, twin A and twin B, respectively. Compared with non-users, women with FA supplementation were (β 17·3, 95 % CI 6·1, 28·4; β 166·3, 95 % CI 69·1, 263·5) associated with increased birth weight, lower risk of SGA (OR 0·85, 95 % CI 0·80, 0·92; OR 0·45, 95 % CI 0·30, 0·68) and LBW (OR 0·82, 95 % CI 0·71, 0·95; OR 0·50, 95 % CI 0·33, 0·75) in singletons and twins, and more prominent effects in twins. Moreover, there were significant interactions between FA supplementation and plurality on birth weight, SGA and LBW.Conclusions:The present study suggests the association of periconceptional 0·4 mg/d FA supplementation with increased birth weight and reduced risk of SGA and LBW in both singletons and twins, and this association may be more prominent in twins.

Abstract Background Increased high sensitivity C- reactive protein (hs-CRP) levels have been found in many earlier studies on migraine, and recently also in persons with migraine and insomnia. The aim of this study was to see whether these findings could be reproduced in a large-scale population-based study. Methods A total of 50,807 (54%) out of 94,194 invited aged ≥20 years or older participated in the third wave of the Nord-Trøndelag Health Study study performed in 2006–2008. Among these, 38,807 (41%) had valid measures of hs-CRP and answered questions on headache and insomnia. Elevated hs-CRP was defined as > 3.0 mg/L. The cross-sectional association with headache was estimated by multivariate analyses using multiple logistic regression. The precision of the odds ratio (OR) was assessed with 95% confidence interval (CI). Results In the fully adjusted model, elevated hs-CRP was associated with migraine (OR 1.14, 95% CI 1.04–1.25) and migraine with aura (OR 1.15, 95% CI 1.03–1.29). The association was strongest among individuals with headache ≥15 days/month for any headache (OR 1.26, 95% CI 1.08–1.48), migraine (OR 1.62, 95% CI 1.21–2.17), and migraine with aura (OR 1.84, 95% CI 1.27–2.67). No clear relationship was found between elevated hs-CRP and headache less than 7 days/month or with insomnia. Conclusions Cross-sectional data from this large-scale population-based study showed that elevated hs-CRP was associated with headache ≥7 days/month, especially evident for migraine with aura.

Determinants Of Breastfeeding

Background With rapid industrialization and urbanization, there is a growing need for women to enter the workforce, and affluent people are drawn to the infant formula market. The breastfeeding rates in China are below the optimal level. Large scale quantitative research studying breastfeeding practices after 2015 in China are lacking. Research aim We aimed to (1) explore the latest patterns and (2) identify the determinants of breastfeeding in China. Methods The study was a population-based, cross-sectional survey. A multi-stage sampling technique was adopted for the selection of participants. We recruited 10,408 mothers with children under 12 months old, in 12 regions of China, and conducted a questionnaire survey about breastfeeding patterns. The associations between social and biophysical determinants and breastfeeding outcomes were analyzed using a logistic regression model. Results The exclusive breastfeeding rate was 29.32% ( n = 3,052) decreasing from 32.71% ( n = 3,404) to 15.83% ( n = 1,648) among children aged 0–5 months. Cesarean section had a negative association with early breastfeeding initiation ( OR = .33, 95% CI [.30, .36]), exclusive breastfeeding ( OR = .78, 95% CI [.69, .89]), and predominant breastfeeding ( OR = .73, 95% CI [.65, .83]). Compared to participants with an annual household income lower than 40,000 Yuan ($5,817 USD), those with over 100,000 Yuan ($14,542 USD) had an OR of .78 (95% CI [.67, .90]) in exclusive breastfeeding. Compared with illiterate and unemployed groups, middle/high school education and a current work status, respectively, were associated with a lower likelihood of exclusive breastfeeding ( OR = .73, 95% CI [.63, .84]; OR = .58, 95% CI [.37, .89]). Conclusions The prevalence of breastfeeding in 12 selected regions in China was low and interventions focusing on the targeted population should be strengthened.

AbstractObjectiveTo describe nutrient intakes, characterize dietary patterns and analyse their associations with sociodemographic characteristics among pregnant women in Shaanxi, China.DesignPopulation-based cross-sectional survey.SettingTwenty counties and ten districts in Shaanxi Province of Northwest China, 2013.SubjectsWomen (n 7462) were recruited using a stratified multistage random sampling method to report diets during pregnancy, at 0–12 months (median 3 months; 10th–90th percentile, 0–7 months) after delivery.ResultsPregnant women had higher intakes of fat, niacin and vitamin E than the nutrient reference values, while most micronutrients such as vitamin A, folate, Ca and Zn were reportedly low. Women in the highest education, occupation and household income groups had higher nutrient intakes than those in the lowest groups. Nutrient intake differences also existed by geographic area, residence and maternal age at delivery. Three dietary patterns were identified: balanced pattern, vegetarian pattern and snacks pattern. Participants with high balanced pattern scores tended to be better educated, wealthier, 25–29 years old at delivery, working outside and living in urban areas and central Shaanxi. Women with high scores on the vegetarian pattern and snacks pattern tended to be in low balanced pattern score groups, and had lower nutrient intakes than those in the high balanced pattern score groups.ConclusionsThe study suggested that pregnant women in Shaanxi, China had low intakes of most nutrients such as vitamin A, folate and Ca. Dietary patterns and most nutrient intakes varied by sociodemographic characteristics. Targeted programmes are needed to improve dietary intakes and dietary patterns among sociodemographically disadvantaged groups.

Geographically Weighted Logistic Regression

The geographical variation of maternal dietary patterns related to birth outcomes is important for improving the health of mothers and children; however, it is currently unknown. Thus, the objective of the study was to investigate geographical variations of maternal dietary pattern during pregnancy, and evaluate the spatial varying association of maternal dietary patterns in pregnancy with abnormal birth weight. A population-based cross-sectional study was conducted in Shaanxi province in Northwest China in 2013 to evaluate the relationship between abnormal birth weight and dietary pattern using the Geographically Weighted Logistic Regression (GWLR). Three dietary patterns during pregnancy were extracted through factor analysis, explaining approximately 45.8% of the variability of food intake. Approximately 81.6% of mothers with higher scores on the equilibrium pattern was more unlikely to have small for gestational age (SGA) infants, with the lower OR observed in Central and South Shaanxi. The snacks pattern was positively associated with low birth weight (LBW) for 23.2% of participants, with the highest OR in Central Shaanxi. Among about 80.0% of participants with higher scores on the snacks pattern living in South and Central Shaanxi, there was a higher risk for SGA. The OR values tend to descend from South to North Shaanxi. The OR values of the negative association between prudent pattern and LBW decreased from South to North Shaanxi among approximately 59.3% of participants. The prudent pattern was also negatively associated with the increasing risk of fetal macrosomia among 19.2% of participants living mainly in South Shaanxi. The association of maternal dietary patterns during pregnancy with abnormal birth weight varied geographically across Shaanxi province. The findings emphasize the importance of geographical distribution to improve the dietary patterns among disadvantaged pregnant women.

Abstract To investigate the prevalence of CSS in a general population. A large-scale cross-sectional study on 21,661 residents (7,531 men, 14,130 women) in a community in Japan was performed. CSS were assessed using Central Sensitization Inventory (CSI-A, B). Participants with a CSI-A score ≥40 was defined as having CSS. Age, sex, district, CSI-B (10 CSS-related diseases), lifestyle, and mental health factors were rated in a self-reported survey. The prevalence of CSS and its relationship with potential factors were examined by sex using descriptive and logistic regression models. The prevalence of CSS was 5.4% (95% Confidence Interval (CI) 5.1 to 5.7) in all participants. It significantly differed between men (3.6%, 95% CI 3.2 to 4.1) and women (6.3%, 95% CI 5.6 to 6.7). A CSI-A score ≥40 correlated with more than one CSI-B disease, exercise habits, sleeping hours per day, perceived stress, and resilience in both men and women. In women, age, ex-smokers, coffee intake (≥1 day per week), and alcohol intake correlated with CSS. The prevalence of CSS was 5.4% in the community examined and was higher in women than in men. CSS-related diseases and many factors correlated with CSS. The present results provide important information for future research on CSS.

Abstract Background: Alcohol use during pregnancy is a modifiable health behavior that causes a range of health problems in infants, including impaired growth, stillbirth, and fetal alcohol spectrum disorder. However, there is lack of comprehensive information on alcohol use and associated factors during pregnancy using a population-based dataset in Ethiopia. Therefore, this study aimed to assess the prevalence of alcohol use during pregnancy and associated factors using a national, population-based survey.Methods: The study utilized data from the 2011 and 2016 Ethiopian Demographic and Health Survey, a cross-sectional survey conducted on a nationally representative sample. The survey employed a multistage cluster sampling method to generate representative national and sub-national health and health related indicators. A total of 2,341 pregnant women were included in the analysis. Factors associated with alcohol use were identified using multivariable logistic regression model. Adjusted odds ratios (AOR) with 95% confidence interval (CI) were computed to quantify the degree of association between independent variables and alcohol use.Results: In Ethiopia, the prevalence of alcohol use among pregnant women was 30.2% (95% CI: 28.4%-32.2%). The study identified that being employed (AOR: 2.07; 95%CI: 1.55-2.77), ever attempted termination of pregnancy (AOR: 2.21; 95% CI: 1.60-3.05), having two (AOR: 2.56; 95% CI: 1.76-3.72), or three (AOR: 2.98; 95% CI: 1.40-6.35) sexual partners in lifetime and chat chewing (AOR: 8.91; 95% CI: 4.61-17.23) had increased the odds of alcohol use during pregnancy.Conclusion: In this study, the prevalence of alcohol use during pregnancy among Ethiopian mothers was high. Working status, ever used something to terminate the pregnancy, more than one lifetime partner, and chat chewing were factors associated with alcohol use during pregnancy. Thus, prevention interventions and strategies can draw on the identified modifiable health behaviors.

ObjectiveThis study determines the magnitude and pattern of animal-related injury mortalities and morbidities in rural Bangladesh.Design and settingA cross-sectional survey was conducted in 51 Unions of 7 subdistricts of Bangladesh from June 2013 to September 2013.ParticipantsA total of approximately 1.17 million individuals across all age and gender profiles were included in the survey. The participants had to be residents of the seven subdistricts and have provided consent to participate in the study.Primary and secondary outcome measuresAnimal-related injury characteristics and demographic information was collected in the study. Frequency, proportion and 95% CIs of variables such as type of animal, type of animal attack, activity of the person prior to attack and the seasonality of the injury were reported. Data was then statistically analysed for associations between injury and sociodemographic characteristics.ResultsThe incidence rate of fatal and non-fatal animal-related injuries across all ages were 0.7 (95% CI 0.4 to 1.4) and 1635.3 (95% CI 1612.0 to 1658.0) per 100 000 populations, respectively. Non-fatal animal-related injury rates were highest among adults 18 years and older (1820.6 per 100 000 population (1777.2 to 1865.1)), and in males across all age groups. The most common animal injury was wasp/hornet/bee sting (49%), followed by cow/buffalo (25%), dog bite (9%) and snake bites (9%).ConclusionsAnimal-related injuries are an important public health issue in rural Bangladesh. The incidence of animal-related morbidities was found high in the study area. Males, school-going and productive age groups were at high risk. Immediate attention should be given to prevent these events.
