Gestational weight gain and unplanned or emergency cesarean delivery in the United States

BACKGROUND In the United States, the rates of cesarean delivery are well above the World Health Organization recommended target. Although obesity is a widely established risk factor for cesarean delivery, there is limited population-based research that examines the relationship between gestational weight gain and cesarean delivery. OBJECTIVE To determine the association between gestational weight gain and unplanned or emergency cesarean delivery. METHODS We examined 2107 mothers from the Infant Feeding Practices Study II 2005-2007. The Institute of Medicines current guidelines were used to define categories of gestational weight gain: inadequate (less than the recommended guideline), adequate (within the recommended guideline) and excessive (above the recommended guideline). FINDINGS Approximately 49.3% and 13.6% of the participants had excessive weight gain and unplanned or emergency cesarean delivery, respectively. A Greater proportion of women with excessive weight gain had an unplanned or emergency cesarean delivery followed by women with adequate and inadequate weight gain, respectively (17.8%, 10.0%, 8.8%; p<0.001). In the multivariable model, compared to women with adequate weight gain, the odds of unplanned or emergency cesarean delivery were higher among women with excessive weight gain (OR 1.56, 95% CI 1.07-2.27, p=0.020). DISCUSSION Women with excessive gestational weight gain are more likely to experience an unplanned or emergency cesarean delivery, which increases the risk for poor maternal-infant health outcomes. CONCLUSION It is critical to identify populations at increased risk of unplanned or emergency cesarean delivery and provide preconception and prenatal counseling to achieve and maintain the recommended weight gain for optimal maternal-infant health outcomes.

Association Between Risky Sexual Behavior and Cervical Cancer Screening Among Women in Kenya: A Population-Based Study

Women residing in Eastern Africa are disproportionately affected by cervical cancer. Previous studies have identified risky sexual behavior as a major risk factor for cervical cancer. However, population-based studies examining the relationship between sexual behavior and cervical cancer screening are currently lacking. This descriptive cross-sectional study utilized nationally representative secondary data from the 2014 Kenya Demographic and Health Survey (n = 6104) to examine the association between risky sexual behavior and cervical cancer screening among sexually active women. Both descriptive and inferential statistical methods were utilized. Overall, 20.2% of the study sample reported having cervical cancer examination. Approximately 13.1% of the participants reported involvement in risky sexual behavior. Significantly lower proportion of women engaged in risky sexual behavior reported having cervical cancer examination (14.5 vs. 21.0%; p = 0.001). In the multivariable model, we found a significant interaction between risky sexual behavior and marital status on cervical cancer examination. Among women who were married/living together, risky sexual behavior was negatively associated with cervical cancer examination after adjusting for potential confounders (Prevalence Ratio, 95% CI) (0.42; 0.24–0.74; p = 0.002). The prevalence of having visual inspection with VIA or VILI were lower among women who were involved in risky sexual behavior (0.39; 0.18–0.87; p = 0.022). However, we were unable to detect any significant association between risky sexual behavior and having Papanicolaou test. With increasing incidence of cervical cancer in resource-limited settings, it is critical to identify populations at increased risk of infection and provide effective screening and follow-up services.

Association of Youth Characteristics and Recent Utilization of Dental Services in the United States

Background: Oral health is important for overall health of youth, although dental service utilization is lower than national goals. The purpose of the study was to identify sociodemographic and health behavioral characteristics of youth in the United States who reported having at least one dental visit in the past 12 months. Methods: Secondary data analysis was conducted using the 2015 Youth Risk Behavior Survey (YRBS) to examine factors associated with dental care utilization using Andersens theory-based Behavioral Model of Health Care Utilization. Results: Among 5,814 youth, nearly 78 percent reported visiting a dentist in the past 12 months. After adjusting for potential confounders, characteristics significantly associated with higher likelihood of dental care utilization were: predisposing factors of non-Hispanic white ethnicity and health behavior characteristics of not using tobacco, not using illegal substances, not drinking soda, and wearing a seat belt; enabling factor of speaking English well; and perceived health of not being overweight. Discussion: Use of the Healthcare Utilization Model identified significant factors classified as predisposing, enabling, and need-related factors associated with youths utilization of dental care services. Findings from the theory-based population-based study informs healthcare providers of factors to consider when promoting dental care among youth.

Factors That Modify the Association of Maternal Postpartum Smoking and Exclusive Breastfeeding Rates

BACKGROUND AND OBJECTIVE Maternal postpartum smoking increases the risk for poor infant health outcomes, while exclusive breastfeeding has been shown to support infant health. Limited population-based research has been published on the interaction between maternal smoking and exclusive breastfeeding. The objective of this study was to examine factors modifying the association between maternal postpartum smoking and exclusive breastfeeding among women in the United States. METHODS Secondary data analysis was conducted using the 2009-2011 Pregnancy Risk Assessment Monitoring System. Stratified analyses were used to examine the associations between maternal postpartum smoking and exclusive breastfeeding by sociodemographic factors. RESULTS The postpartum smoking rate was 17.1%. The relationship between postpartum smoking and exclusive breastfeeding at 12 weeks varied by maternal education level, race/ethnicity, Medicaid use, and pregestational or gestational diabetes. The magnitude of reduction in the odds of exclusive breastfeeding at 12 weeks postpartum among the women who smoked in the postpartum period ranges from odds ratio (95% confidence interval) 0.52 (0.37-0.74) for non-Hispanic blacks to 0.31 (0.22-0.43) for women who had <12 years of education. CONCLUSIONS Women who smoked in the postpartum period, who also suffered from socioeconomic disadvantages, had a higher likelihood of not continuing exclusive breastfeeding. Identification of women at high risk for not exclusively breastfeeding is important for targeting populations in need of appropriate and timely support for prenatal and postpartum smoking cessation and breastfeeding promotion.

The relationship between history of hormonal contraceptive use and iron status among women in Tanzania: A population-based study

OBJECTIVES Approximately 30% of the Tanzanian women in the reproductive age group are iron deficient. At population-level, there is a dearth of research on the relationship between hormonal contraceptive use and iron deficiency. The study objective was to examine the relationship between history of hormonal contraceptive use and iron status among women in Tanzania. STUDY DESIGN We conducted a cross-sectional study analysis including 4186 women who participated in the population-based 2010 Tanzania Demographic and Health Survey. MAIN OUTCOME MEASURE Iron status determined by iron deficiency, anemia, and iron deficiency anemia. RESULTS Almost 19.0% women reported history of hormonal contraceptive use. Nearly, 30.0%, 39.5%, and 14.3% women had iron deficiency, anemia and iron deficiency anemia respectively. History of hormonal contraceptive use was negatively associated with iron deficiency, anemia and iron deficiency anemia, independent of potential confounders. Compared to non-users, the multivariable-adjusted odds ratio OR (95% CI) among hormonal contraceptive users was 0.73 (0.56-0.94, p<0.05) for iron deficiency, 0.58 (0.46-0.72, p<0.001) for anemia, and 0.53 (0.37-0.74; p<0.001) for iron deficiency anemia. Longer duration of hormonal contraceptive use (>2years) had lesser odds of iron deficiency 0.63 (0.43-0.91, p for trend 0.005), anemia 0.51 (0.36-0.73, p for trend <0.001) and iron deficiency anemia 0.35 (0.19-0.65, p for trend <0.001). CONCLUSION Our finding has important implications for educating healthcare providers and women about additional nutritional benefits of the use of hormonal contraceptives.

Association Between Type of Health Professional at Birth and Exclusive Breastfeeding

INTRODUCTION Although benefits of breastfeeding for infants, women, and society are well established, breastfeeding rates in the United States remain below the Healthy People 2020 goals. Various factors are known to influence breastfeeding practices. Limited research has been conducted to examine the influence of type of birth attendant on exclusive breastfeeding. METHODS A cross-sectional analysis was conducted using data from the Infant Feeding Practices Study II collected between May 2005 and June 2007. RESULTS The study sample included 2026 women, aged 18 years or older. At discharge, 74.6% of women exclusively breastfed, and 27.6% exclusively breastfed at 3 months postpartum. Bivariate analysis showed a statistically significant association between type of health professional at birth and exclusive breastfeeding at discharge (P = .001) and 3 months postpartum (P < .001). After adjusting for potential confounders, the association between type of health professional at birth and exclusive breastfeeding at discharge was no longer significant. However, the odds of exclusive breastfeeding at 3 months postpartum were higher among women whose birth was attended by a midwife or nurse-midwife compared to those whose birth was attended by an obstetrician (odds ratio [OR], 1.87; 95% confidence interval [CI], 1.34-2.61; P < .001). DISCUSSION Exclusive breastfeeding continuation may be influenced by the type of health professional attending the birth. In addition to having a skilled workforce, health care professionals involved in perinatal care need to be educated and trained to promote and support exclusive breastfeeding as recommended. The complex and multifactorial nature of the maternal decision to exclusively breastfeed requires broader understanding of contextual factors.

The Moderating Effect of Urban Versus Rural Residence on the Relationship Between Type of Birth Attendant and Early Initiation of Breastfeeding in Ghana

Background: Early initiation of breastfeeding increases the likelihood of longer duration of breastfeeding. Factors associated with breastfeeding include maternal sociodemographic, behavioral and health-related characteristics, infant health characteristics, and perinatal factors. Research aim: This study aimed to determine the association between type of birth attendant and early initiation of breastfeeding among women in Ghana. Methods: A cross-sectional study was conducted using women (N = 3,087) who participated in the 2014 Ghana Demographic and Health Survey. The main outcome of interest was early initiation of breastfeeding, defined as provision of mother’s milk to the infant within 1 hr of birth. Chi-square tests and multivariable logistic regression modeling were performed. Results: Breastfeeding was initiated within 1 hr of birth by 58.3% of women. In the multivariable model, there was a significant interaction between type of birth attendant and place of residence on early initiation of breastfeeding. For rural areas, compared with women who had a nurse or midwife as their birth attendant, the multivariable odds ratios [95% confidence intervals] for early initiation of breastfeeding were lower among women whose birth attendant was a relative or other, 0.20 [0.07, 0.55], p = .002; village health volunteer or traditional health practitioner, 0.21 [0.07, 0.62], p = .005; none, 0.34 [0.12, 0.93], p = .035; community health officer, 0.42 [0.21, 0.85], p = .016; and doctor, 0.48 [0.24, 0.96], p = .037. For urban areas, no significant association was detected between type of birth attendant and early initiation of breastfeeding. Conclusion: Findings from the study highlight the need for focused, context-specific, early initiation of breastfeeding promotion and intervention, especially for women and their birth attendants in rural areas.
