“…14 Furthermore, in the present study from 2010 to 2013, the rates of macrosomia rose from 6.3% to 7.2%, which was likely to be much higher than reported in Guangdong, China, in 2012 (2.3%) and South China in 2011 (5.6%). 15 – 16 They were also higher than that reported by the 2008 World Health Organization global survey for India (0.5%), Vietnam (3.4), and Thailand (2.2%). 17 Although LBW rates have been decreasing in Northwest China, macrosomia may become an important problem there.…”

Changes in Socioeconomic Inequality of Low Birth Weight and Macrosomia in Shaanxi Province of Northwest China, 2010–2013

Socioeconomic disparities in birth weights (BWs) are associated with lifelong differences in health and productivity. Understanding socioeconomic disparities in BW is presently of concern to develop public health interventions that promote a good start in life in Northwest China. In the study, our objective is to investigate the socioeconomic disparities in low and high BW from 2010 to 2013 in this region.Those single live births were recruited using a stratified multistage sampling method in Shaanxi province from August to December 2013. Data were collected with a structured questionnaire and a review of birth certificates. Socioeconomic status (SES) was stratified based on the calculated household wealth index. Prevalence differences (PDs) and concentration indices (CIs) were used to depict the SES inequality of low BW (LBW) and macrosomia.Information for 28722 single live births born were obtained in Shaanxi province. From 2010 to 2013, the overall rates of LBW decreased, and the difference in LBW across differing SES groups decreased by 0.7% (boys, 0.4%; girls, 0.8%). From 2010 to 2013, the overall rates of macrosomia increased by 14.3% (boys, 17.5%; girls, 7.8%), whereas the PDs in macrosomia across various SES groups remained unchanged. From 2010 to 2013, concentration indices for SES inequalities in LBW and macrosomia confirmed the results shown by differences in prevalence. Compared with mothers of high SES, those in low SES group were significantly older, less educated, engaged in farming with less availabile healthcare, and engaged in unhealthy lifestyles (eg, exposure to secondhand smoke) during pregnancy, regardless of the baby's sex.From 2010 to 2013, in Shaanxi province, the negative association between socioeconomic status and LBW weakened. Rates of macrosomia were higher in those of high SES, but the SES disparities varied insignificantly over the same time. Our findings may provide valuable insights to direct healthcare policies for pregnant women to reduce inequalities in health, quality of life, and productivity for their children as they age into adulthood.

“…25 Another study found that for mothers older than 40 years, there was a strong risk for extreme LBW. 15 Highly educated mothers are more likely to have better jobs and higher incomes, as well as more knowledge of prenatal care. According to epidemiologic evidence, BW increased with mothers’ education level.…”

“…Women are postponing childbearing to their late 35s, 40s and beyond almost all around the world. [1][2][3][4][5][6][7] It is consensual that the desire to build successful careers and have equal opportunities in the job market, as well as attaining financial stability, are major concerns to most women nowadays. 4,8 In less resourced countries, childbearing is more common amongst multiparous older women due to ineffective family planning methods and favourable cultural disposition towards a large family size.…”

Advanced Maternal Age: Adverse Outcomes of Pregnancy, A Meta-Analysis

et al. 2019

Introduction: The risks of pregnancy in women of advanced maternal age are not consensual amongst studies. The aim of this metaanalysis was to determine whether women of advanced maternal age (≥ 35 years old) had worse obstetrical and perinatal outcomes than non- advanced maternal age women (20 - 34 years old) in singleton, naturally-conceived pregnancies.Material and Methods: We searched PubMed/ MEDLINE, IndexRMP and the Cochrane Database of Systematic Reviews. Ten studies were included according to the following criteria: population of > 1000 nulliparous and/or multiparous women with singleton gestations who did not undergo any type of infertility treatment. Using Review Manager v. 5.3, two meta-analysis were performed: one comparing the outcomes of 20 - 34-year-old vs 35 - 40-year-old women, and another comparing the outcomes of 35 - 40-year-old women vs > 40-year-old women.Results: Women aged 35 - 40 years old were more likely to have > 12 years of education than 20 - 34 years old and > 40 years old women. Advanced maternal age women (35 - 40 and > 40 years old) were more likely to be overweight and having gestational diabetes and gestational hypertension. They were also more likely to undergo induced labour and elective caesarean deliveries. Furthermore, they had worse perinatal outcomes such as preterm delivery, low birthweight babies, higher rates of Neonatal Intensive Care Unit admission and worse Apgar scores. Advanced maternal age women had higher rates of perinatal mortality and stillbirth.Discussion: Most authors present similar results to our study. Although the majority of adverse outcomes can be explained through the physio-pathological changes regarding the female reproductive apparatus that come with aging and its inherent comorbidities, according to the existing literature advanced maternal age can be an independent risk factor per se. In older pregnant women without comorbidities such as gestational hypertension or diabetes there are still worse obstetric and perinatal outcomes, which indicate that advanced maternal age is an independent strong risk factor alone.Conclusion: Advanced maternal age women are at a higher risk of adverse obstetrical and perinatal outcomes. In both comparisons, worse outcomes were more prevalent in the older group, suggesting that poorer outcomes are more prevalent with increasing age.

“…Preterm birth and abnormal fetal growth (including small for gestational age [SGA] and large for gestational age [LGA]) are important predictors of neonatal morbidity and mortality as well as adverse health outcomes in childhood and adulthood . A recent study in seven regions in China suggests a preterm birth rate of 7.1% in 2011, and data from Guangzhou, the largest city in southern China, indicate the prevalence of SGA and LGA being 8.6% and 8.5%, respectively . While the rates are not particularly high compared to those of south Asia (13.3%) and sub‐Saharan Africa (12.3%), given the large absolute number of live births in China (12% of global total in 2010), identification of risk factors associated with preterm birth and abnormal fetal growth is of particular public health importance.…”

Does tea consumption during early pregnancy have an adverse effect on birth outcomes?

We did not identify a consistent association between frequency of tea consumption or tea strength and adverse birth outcomes among Chinese pregnant women with low tea consumption. Our findings suggest that occasional tea drinking during pregnancy is not associated with increased risk of preterm birth or abnormal fetal growth. Given the high overall number of annual births in China, our findings have important public health significance.
