Relationships among smoking, drinking, betel quid chewing and pregnancy-related nausea and vomiting in Taiwanese aboriginal women

Effects of passive smoking on severe nausea and vomiting of pregnancy among urban Chinese nonsmoking women

Background

Nausea and vomiting of pregnancy (NVP) is one of the most common pregnancy-associated symptoms, but little is known about the effects of passive smoking on this symptom. Passive smoking among women is widespread and severe in China due to the high proportion of men who smoke actively. The aim of this study is to examine the association between maternal passive smoking and severe NVP in early pregnancy among nonsmoking women in urban China.

Methods

We collected information on passive smoking status and severe NVP in early pregnancy based on an ongoing prospective cohort study conducted from October 2017 to May 2019 in Beijing, China. We used multivariable logistic model to calculate adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) after controlling for confounding factors.

Results

Among 3064 participants who were involved in the final analysis, 7.4% (n = 227) were passive smokers and 9.8% (n = 299) reported severe NVP. After adjusting for potential confounders, passive smoking conferred an increased risk of NVP (adjusted OR = 1.62, 95% CI: 1.08, 2.43). The frequency of exposure to second-hand smoke showed a positive relationship with the risk of severe NVP, and significant subgroup differences were also observed in stratified analyses by parity and education level.

Conclusions

Our results suggested that maternal exposure to second-hand smoke remained to be a major public health problem in urban China, and that passive smoking during the first trimester may increase the risk of severe NVP among nonsmoking pregnant women. Measures should be taken to reduce the impact of second-hand smoke exposure on pregnant women.

Pre-Pregnancy Risk Factors for Severe Hyperemesis Gravidarum: Korean Population Based Cohort Study

Hyperemesis gravidarum is known to be associated with poor perinatal outcomes. This study aimed to identify pre-pregnancy risk factors for hospital admission in women with hyperemesis gravidarum. We enrolled women who had delivered between 1 January 2013 and 31 December 2015, and had undergone a national health screening examination through the National Health Insurance Corporation 1-2 years before their first delivery. Multiple logistic regression analysis was performed to estimate the risk factors for hospital admission due to hyperemesis gravidarum. Of the 216,373 study participants with hyperemesis gravidarum, 2210 (1.02%) pregnant women were hospitalized. These women had lower waist circumference and were underweight based on body mass index compared to pregnant women who did not require hospitalization due to hyperemesis gravidarum. On multivariate analysis, primiparity, multiple pregnancies, female fetus, alcohol consumption, and pre-pregnancy underweight status were associated with an increased risk of hospitalization due to the condition. In this population-based cohort study, we found that hospitalization due to hyperemesis gravidarum was associated with pre-pregnancy lifestyle characteristics. Early recognition and management of these pre-pregnancy factors may help control the need for hospitalization in women with the condition in subsequent pregnancies.

Gestational risk factors and childhood cancers: A cohort study in Taiwan

Gestational risk factors such as birth weight, gestational age and parity have been repeatedly found to be related to pediatric cancers, but few reports have emerged from Asian countries. Here we report on demographic and gestational factors in a Taiwanese cohort. Our study included all children born in Taiwan 2004-2014 for whom there was a birth record (n = 2,079,037), of which 1900 children had been diagnosed with cancer prior to age 12. We conducted multivariable hazard regression to examine associations between demographic and gestational factors with cancer. Greater parity (family with 2+ older children) was related to acute myeloid leukemia [Hazard ratio (HR) = 2.15, 95% confidence interval (CI): 1.31, 3.55), central nervous system tumors (HR = 1.67, CI: 1.13, 2.48) and neuroblastoma (HR = 1.67, CI: 1.07, 2.63). Hepatoblastoma cases had a higher risk of low birth weight (<2,500 g; HR = 3.01, CI: 1.85, 4.91), very preterm birth (<33 weeks gestation; HR = 13.71, CI: 7.45, 25.23), plural pregnancies (HR = 2.37, CI: 1.10, 5.14) and both small (HR = 2.13, CI: 1.23, 3.67) and large (HR = 1.83, CI: 1.01, 3.32) for gestational age. Germ cell tumors were more common among children born in rural areas (HR = 1.63, CI: 1.02, 2.60). Despite that Taiwan has lower rates of both high and low birthweight compared to other developed nations, we observed several similar associations to those reported in Western Countries. Further research should examine unique exposures in Taiwan that may be contributing to higher incidence of certain cancer types.

Betel Nut Use: The South Asian Story

Background: Few traditions in South Asia have the antiquity and universal acceptance of betel quid and areca nut chewing. Its popularity dates back to ancient times in the South-Asian community with a foundation based on four factors, i.e. social acceptability, religious beliefs, perceived health benefits and addiction. We aim to provide an overview of its use in the South Asian region. Methods: We performed an electronic search on Medline, Embase and Google Scholar to identify the origins of the various betel quid and areca nut practices pertaining to the South Asian region along with their social and cultural influences. We also studied the prevalence across the region and the health effects, especially carcinogenic, along with the impact of diverse immigration today. Results: Other than the debate of where it originates, there is a diverse plethora of terms and methods of use of areca nut and betel quid in the region. Although established as a known carcinogen, the incidence is high, especially in the Indian subcontinent, with very few studies focusing on its use alone (without tobacco). The effect of globalization and increased movement of Asians across borders is resulting in changes in the patterns of diseases as well due to wider dissemination of areca nut and betel quid use. Conclusions: There is a huge loss of lives due to the addiction that areca nut causes. Governments need to tightly regulate the laws and set up tailored programs to tackle this specific issue in this region.

Systematic review of areca (betel nut) use and adverse pregnancy outcomes

BACKGROUND

Betel nut is the fourth most commonly abused substance worldwide and has been associated with significant adverse health outcomes. Little is known about its effects on the fetus.

OBJECTIVE

To perform a systematic review of studies investigating prenatal betel nut use and adverse perinatal outcomes.

SEARCH STRATEGY

Pubmed, Embase, and Cochrane databases were searched from inception until July 2018 using the terms areca, betel nut, pregnancy, pregnancy complications, and infection.

SELECTION CRITERIA

Eligible studies included case-control, cohort, and randomized control studies involving pregnant women.

DATA COLLECTION AND ANALYSIS

Where appropriate, bivariate meta-analysis was performed, and odds ratios (ORs) and 95% confidence intervals (CIs) were calculated.

MAIN RESULTS

In total, 28 studies were screened and eight studies (including 15 270 women) were included in the review and meta-analysis. Preterm birth, low birthweight, and anemia were most commonly investigated. Meta-analysis revealed a significant association between betel nut use and low birthweight, with a pooled OR of 1.75 (95% CI, 1.35-2.27).

CONCLUSIONS

The review identified only eight eligible studies, all based in the Asia-Pacific region. There was a significant association between low birthweight and betel nut exposure in pregnancy. Further prospective studies are needed to confirm this association.

Psychometric Properties of the Short Form of the Health Practices Questionnaire-II Chinese Version

OBJECTIVE

To examine the psychometric properties of the Health Practice Questionnaire-II Chinese version (HPQ-II CV), a self-report instrument designed to measure the health behaviors of pregnant women.

DESIGN

Cross-sectional, psychometric design.

SETTING

Prenatal clinics of four hospitals in southern Taiwan.

PARTICIPANTS

Two convenience samples, 368 pregnant women in Phase 1 and 289 pregnant women in Phase 2.

METHODS

In Phase 1, the 34-item HPQ-II was translated into Chinese. Then, we explored the factor structure of the HPQ-II CV using exploratory factor analysis, determined the factors of the HPQ-II CV, and shortened the length of the scale. In Phase 2, we used confirmatory factor analysis to cross-validate the factor structure of the 13-item HPQ-II CV.

RESULTS

In Phase 1, we used item analysis to reduce the 34-item HPQ-II CV to 21 items. Using exploratory factor analysis and parallel analysis, we shortened the 21-item HPQ-II CV to 15 items grouped in four factors: Taking Safety Measures (4 items), Eating A Healthy Diet (3 items), Coping With Uncertainty (3 items), and Seeking Help From Professionals (5 items), which accounted for 45.70% of the total variance. In Phase 2, two items were removed from the 15-item HPQ-II CV after confirmatory factor analysis. Cronbach's alpha coefficient of the 13-item HPQ-II CV was .80, and the cross-sample validity supported the best-fit model for the 13-item HPQ-II CV.

CONCLUSION

We found acceptable validity and reliability statistics for the 13-item HPQ-II CV when administered to pregnant, Taiwanese women.

Harmful alcohol use among Aboriginal people in southern Taiwan: the prevalence, correlates, and adverse drinking effects

This cross-sectional study aims to examine the prevalence and correlates of harmful alcohol use among aboriginal people in southern Taiwan and to examine the associations between harmful alcohol use and adverse drinking effects. Four hundred forty-nine aboriginal adults were recruited from two townships in southern Taiwan to complete the questionnaires. Among the aborigines, 59.7% scored an 8 or above on the Alcohol Use Disorders Identification Test, including 26.7% who were found to be hazardous drinkers (AUDIT level II), 18.5% who were harmful drinkers (level III), and 14.5% who were with likely dependence (level IV). Male aborigines who participated less in religious activities, had stressful life events, were cigarette smokers, or were betel quid chewers were more likely to have harmful alcohol use. Harmful alcohol use was also associated with an inability to work and with arguments with other people. Our study suggests that aboriginal people in southern Taiwan experience alcohol-related risks at rates as high as other worldwide populations for which AUDIT results are available. Individuals with AUDIT scores at levels II and III are generally candidates for brief interventions delivered in generalist health settings. Individuals with AUDIT scores at level IV should be referred for an addiction specialty evaluation and possible treatment as well as lower-risk individuals (those with AUDIT levels II-III) if they have concurrent physical or psychiatric disorders.

Health Care Providers' Perceptions of Maternal Health Concerns in the Solomon Islands

PURPOSE

The objective of this study was to explore the maternal health risk factors and sentinel events among women in the Solomon Islands, from the viewpoints of health care providers in the Solomon Islands.

DESIGN AND METHOD

Three focus group interviews were conducted in July and August 2011 at a secondary referral hospital in an urban area. The study consisted of 10 registered nurses and 11 skilled birth assistants. Thematic analysis was used for this qualitative data analysis.

FINDINGS

Six major themes were emerged from the data: (a) environmental hazard: malaria, (b) malnutrition: iron deficiency anemia, (c) adolescent pregnancy, (d) betel nut chewing, (e) cultural beliefs influencing women's health, and (f) difficulty accessing health care services.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

The results of this study provide a useful first step toward identifying specific maternal health risks among women in the Solomon Islands. The findings may assist the health sector and midwives/antenatal educators to better understand the health risks and reduce the disease burden among pregnant women in South Pacific countries. The results may also contribute to the development of policies to improve maternal health and to accelerate progress toward the fifth target goal of UNICEF's Millennium Development Goals.

Maternal body composition, smoking, and hyperemesis gravidarum

PURPOSE

To study associations between maternal prepregnant body mass index (BMI), smoking, and hyperemesis gravidarum (hyperemesis).

METHODS

The sample consisted of 33,467 primiparous women from the Norwegian Mother and Child Cohort Study (1999-2008). Data on hyperemesis, BMI, education, maternal age, eating disorders, maternal and paternal smoking habits were obtained from questionnaires. All associations were studied by logistic regression.

RESULTS

Altogether, 353 (1.1%) women had hyperemesis. Among non-smokers, both underweight and obese women were more likely to develop hyperemesis than normal-weighted women: odds ratio (OR), 2.36; 95% confidence interval (95% CI), 1.43-3.88 and OR, 1.48; 95% CI, 1.00-2.20, respectively. No associations were found among smokers. Women who smoked daily (OR, 0.44; 95% CI, 0.32-0.60) or occasionally (OR, 0.64; 95% CI, 0.44-0.93) had lower risk of hyperemesis than non-smokers. No effect of partner's smoking habits was observed.

CONCLUSIONS

Both underweight and obesity were associated with hyperemesis, but only among non-smokers. Maternal prepregnant smoking reduced the risk of hyperemesis, whereas partner's smoking habits had no effect.

Nursing knowledge about alcohol use and alcohol problems in women: a review of the literature

In this article, the authors review the nursing empirical literature on alcohol and women's health published over the past 5 years (2005-2010). A total of 36 data-based articles authored by nurse investigators met eligibility criteria and were included in this review. Most were single studies by individual nurse investigators; few studies reflected ongoing programs of research related to alcohol and women's health. Studies were categorized into four main groups, including (a) determinants of alcohol use and alcohol problems; (b) patterns of use, assessment of alcohol use, and comorbidity; (c) consequences of alcohol use; and (d) the effects of treatment or specific interventions and the contributions of nursing research to the knowledge base of each group are summarized. The authors then propose a research agenda for nursing that addresses the most pressing issues related to alcohol use and alcohol problems in women.
