Antenatal Care Attendance,a Surrogate for Pregnancy Outcome? The Case of Kumasi,Ghana

Antenatal care (ANC) has been shown to influence infant and maternal outcomes. WHO recommends 4 ANC visits for uncomplicated pregnancies. However, pregnant women in Ghana are required to attend 8–13 antenatal visits. We investigated the association of ANC attendance with adverse pregnancy outcomes (defined as low infant birth weight, stillbirth, preterm delivery or small for gestational age). A quantitative cross-sectional study was conducted on 629 women, age 19–48 years who presented for delivery at two selected public hospitals and 16 traditional birth attendants from July to November 2011. Socio-demographic and antenatal information were collected using a structured questionnaire. ANC attendance, medical and obstetric/gynecological history were abstracted from maternal antenatal records. Data were analyzed using Chi square and logistic regression. Twenty-two percent of the women experienced an adverse outcome. Eleven percent of the women attended <4 ANC visits. In an unadjusted model, these women had an increased likelihood of experiencing an adverse outcome (OR 2.27; 95 % CI 1.30–3.94; p = 0.0038). High parity (>5 children) was also associated with adverse birth outcomes. Women screened for syphilis or use of insecticide-treated bed nets had a 40 and 36 % (p = 0.0447 and p = 0.0293) reduced likelihood of experiencing an adverse pregnancy outcome respectively. After adjusting for confounders, attending <4 antenatal visits was associated with adverse pregnancy outcome compared with ≥4 ANC visits (Adjusted OR 2.55; 95 % CI 1.16–5.63; p = 0.0202). Attending <4 antenatal visits and high parity were associated with adverse pregnancy outcomes for uncomplicated pregnancies.     

Health Status and Health Insurance Coverage of Women with Live-Born Infants: An Opportunity for Preventive Services After Pregnancy

Most women in the US have access to health care and insurance during pregnancy; however women with Medicaid-paid deliveries lose Medicaid eligibility in the early postpartum period. This study examined the association between health insurance coverage at the time of delivery and health conditions that may require preventive or treatment services extending beyond pregnancy into the postpartum period. We used 2008 Pregnancy Risk Assessment Monitoring System data from 27 states (n = 35,980). We calculated the prevalence of maternal health conditions, including emotional and behavioral risks, by health insurance status at the time of delivery. We used multivariable logistic regression to assess the association between health insurance coverage, whether Medicaid or private, and maternal health status. As compared to women with private health insurance, women with Medicaid-paid deliveries had higher odds of reporting smoking during pregnancy (adjusted odds ratio [AOR]: 1.85, 95 % confidence interval [CI]: 1.56–2.18), physical abuse during pregnancy (AOR: 1.73, 95 % CI: 1.24–2.40), having six or more stressors during pregnancy (AOR: 2.48, 95 % CI: 1.93–3.18), and experiencing postpartum depressive symptoms (AOR: 1.24, 95 % CI: 1.04–1.48). There were no significant differences by insurance status at delivery in pre-pregnancy overweight/obesity, pre-pregnancy physical activity, weight gain during pregnancy, alcohol consumption during pregnancy, or postpartum contraceptive use. Compared to women with private insurance, women with Medicaid-paid deliveries were more likely to experience risk factors during pregnancy such as physical abuse, stress, and smoking, and postpartum depressive symptoms for which continued screening, counseling, or treatment in the postpartum period could be beneficial.     

A new measurement for optimal antenatal care: determinants and outcomes in Cameroon

A combined measure of optimal antenatal care can provide more information on the role it plays in maternal health. Our objectives were to investigate the determinants of a measure of optimal antenatal care and the associated pregnancy outcomes. Data on 7,557 women taken from the 2004 Demographic and Health Survey in Cameroon were used to develop a new measurement of optimal antenatal care based on four indicators: at least four visits, first visit in first trimester, last visit in third trimester and a professional provider of antenatal care. We studied the relationship of this new variable with other related variables in a multivariate analysis, taking into account the complex study design. Almost sixty six percent of the women had optimal antenatal care. Secondary or higher education (OR 1.74; 95% CI 1.28–2.36), greater wealth (OR 2.31; 95% CI 1.73–3.1), urban residence (OR 1.42; 95% CI 1.12–1.82) and parity of 3–4 (OR 0.79; 95% CI 0.62–0.99) were independently associated with optimal antenatal care. Women with optimal antenatal care were more likely to deliver in a health unit (OR 2.91; 95% CI 2.42–3.49), to be assisted by a skilled health worker during delivery (OR 1.88; 95% CI 1.49–2.37) and to have a baby with a normal birthweight (OR 1.62; 95% CI 1.11–2.38). Obtaining and using a new measure for ANC is feasible. The association of optimal antenatal care to education, wealth and residence in this study, consistent with others, highlights the role of the country’s development in maternal health.     

Risk Factors for Non-use of Skilled Birth Attendants: Analysis of South Sudan Household Survey, 2010

Objectives South Sudan has the lowest percentage of births attended by skilled health personnel in the world. This paper aims to identify potential risk factors associated with non-use of skilled birth attendants at delivery in South Sudan. Methods Secondary data analyses of the 2010 South Sudan Household Health Survey second round were conducted with data for 3504 women aged 15–49 years who gave birth in the 2 years prior to the survey. The risk of non-use of skilled birth attendants was examined using simple and multiple logistic regression analyses. Results The prevalence rates for skilled, unskilled and no birth attendants at delivery were 41 [95 % confidence interval (CI) 38.2, 43.0], 36 [95 % CI 33.9, 38.8], and 23 % [95 % CI 20.6, 24.9] respectively. Multivariable analyses indicated that educated mothers [adjusted odds ratio (AOR) 0.70; 95 % CI 0.57, 0.86], mothers who had three and more complications during pregnancy [AOR 0.77; 95 % CI 0.65, 0.90], mothers who had at least 1–3 ANC visits [AOR 0.38; 95 % CI 0.30, 0.49] and mothers from rich households [AOR 0.52; 95 % CI 0.42, 0.65] were significantly more likely to use skilled birth attendants (SBAs) at delivery. Mothers who lived in rural areas [AOR 1.44; 95 % CI 1.06, 1.96] were less likely to deliver with SBAs. Conclusion Intensive investments to recruit and train more skilled birth attendants’ on appropriate delivery care are needed, as well as building a community-based skilled birth attendants’ program to reduce avoidable maternal mortality in South Sudan.     

Predictors of Poor Pregnancy Outcomes Among Antenatal Care Attendees in Primary Health Care Facilities in Cross River State,Nigeria: A Multilevel Model

Objectives Pregnancy carries a high risk for millions of women and varies by urban–rural location in Nigeria, a country with the second highest maternal deaths in the world. Addressing multilevel predictors of poor pregnancy outcomes among antenatal care (ANC) attendees in primary health care (PHC) facilities could reduce the high maternal mortality rate in Nigeria. This study utilised the “Risk Approach” strategy to (1) compare the risks of poor pregnancy outcomes among ANC attendees by urban–rural location; and (2) determine predictors of poor pregnancy outcomes among ANC attendees in urban–rural PHC facilities in Cross River State, Nigeria. Methods A cross-sectional survey was conducted in 2011 among 400 ANC attendees aged 15–49 years recruited through multistage sampling. Data on risk factors of poor pregnancy outcomes were collected using interviewer-administered questionnaires and clinic records. Respondents were categorised into low, medium or high risk of poor pregnancy outcomes, based on their overall risk scores. Predictors of poor pregnancy outcomes were determined by multilevel ordinal logistic regression. Results A greater proportion of the women in the rural areas were below the middle socio-economic quintile (75 vs. 4 %, p < 0.001), had no education (12 vs. 2 %, p < 0.001), and were in the 15–24 age group (58 vs. 35 %, p < 0.001) whereas women in the urban areas were older than 35 years (10 vs. 5 %, p < 0.001). The women attending antenatal care in the urban PHC facilities had a low overall risk of poor pregnancy outcomes than those in the rural facilities (64 vs. 50 %, p = 0.034). Pregnant women in the urban areas had decreased odds of being at high risk of poor pregnancy outcomes versus the combined medium and low risks compared with those in the rural areas (OR 0.55, 95 % CI 0.09–0.65). Conclusions for Practice Pregnant women attending antenatal care in rural PHC facilities are more at risk of poor pregnancy outcomes than those receiving care in the urban facilities. Health programmes that promote safe pregnancy should target pregnant women in rural settings.     

Women’s Autonomy and Skilled Attendance During Pregnancy and Delivery in Nepal

Objectives This study aims to explore the association between women’s autonomy and skilled attendance during pregnancy and delivery in Nepal. Methods We adopt data from the Nepal Demographic and Health Survey (NDHS, 2011). We include only married women who gave birth in the 5 years preceding the survey (N = 4148). Women’s autonomy was assessed on the basis of four indicators of decision making: healthcare, visiting friends or relatives, household purchases and spending earned money. Each indicator was dichotomized (yes/no) and then summarized into a single variable to measure overall autonomy. Next, we measured health attendance (skilled vs. unskilled) during antenatal and delivery care. The association between women’s autonomy and skilled attendance was analysed using a logistic regression model. Results Most women had a medium (40 %) and high (35 %) level of overall autonomy. The proportion of women accessing skilled providers during antenatal and delivery care was 51 and 36 %. Women with autonomy in healthcare, visiting friends or relatives, making household purchases and spending money earned were associated with a higher likelihood of receiving care from skilled providers during antenatal care and delivery. An elevated probability of access to skilled attendance during antenatal (aOR 1.33; 95 % CI 1.10–1.59) and delivery care (aOR 1.38; 95 % CI 1.12–1.70) was reported among women with higher levels of overall autonomy. Conclusion Women’s autonomy was significantly associated with the maternal health care utilization by skilled attendants. This study will provide insights for policy makers to develop strategies in improving maternal health.     

Low Compliance with Iron-Folate Supplementation Among Postpartum Mothers of Nepal: An Analysis of Nepal Demographic and Health Survey 2011

One in five maternal deaths are directly attributable to anaemia in the world. The World Health Organization recommends iron supplementation from the second trimester of pregnancy to 45 days after delivery. The aim of this study was to determine the compliance rate of iron-folate consumption and the factors associated with iron-folate consumption among post-natal mothers in Nepal. This study utilised the data of Nepal Demographic and Health Survey (NDHS) 2011. The NDHS 2011 is a cross sectional and nationally representative survey. Of the 4,148 respondents, only 20.7 % consumed iron throughout the post-natal period for 45 days. Mothers who had higher and secondary education [adjusted Odd ratio (aOR) 3.101; 95 % CI (2.268–4.240)]; had attended four or more antenatal care visits [aOR 9.406; 95 % CI (5.552–15.938)]; lived in Far-western development region [aOR 1.822; 95 % CI (1.387–2.395)]; delivered in health facility [aOR 1.335; 95 % CI (1.057–1.687)]; and attended postnatal care [aOR 2.348; 95 % CI (1.859–2.965)] were more likely to take iron for 45 days of postpartum. Intervention to increase the compliance with the postpartum iron-folate supplementation are required to avoid adverse pregnancy outcomes associated with poor iron status with especial focus on the mothers who delivered at homes and did not attend post-natal check up.     

Postpartum Depression in Adolescent and Adult Mothers: Comparing Prenatal Risk Factors and Predictive Models

Our objective was to assess whether postpartum depression risk factors differ between adolescent and adult mothers and to evaluate the need for adolescent specific screening instruments. We performed a retrospective cohort study using data from the Rhode Island Pregnancy Risk Assessment Monitoring System, 2004–2008. We identified maternal age specific risk factors using weighted logistic regression and developed predictive models using a forward selected weighted logistic regression. Notable differences in odds ratios were observed for risk factors such as maternal race (OR Hispanic vs. White: 0.99, 95 % CI 0.49–1.99 among adolescents; 3.32, 95 % CI 2.01–5.49 among adults), pre-pregnancy alcohol use (OR use vs. non-use: 2.04, 95 % CI 1.08–3.86 among adolescents; 0.49, 95 % CI 0.33–0.73 among adults), and pregnancy intention (OR unintended vs. intended: 1.05, 95 % CI 0.37–2.97 among adolescents; 2.67, 95 % CI 1.51–4.74 among adults). In predictive models, adolescent postpartum depressive symptoms were most influenced by prior depression and social support while adult postpartum depressive symptoms were associated with risk factors including maternal race, pregnancy intention, SES, prior depression, mental health during pregnancy, stressors, and social support. We were able to identify similarities and dissimilarities in risk factors for postpartum depressive symptoms among adolescents and adults. Predictive models developed in the general population of pregnant women performed poorly among adolescents relative to age specific predictive models, suggesting that current screening tools may not adequately identify high risk adolescents.     

Pregnancy outcomes among visually impaired women in Washington State, 1987–2014

BackgroundWomen with visual impairment may have reduced ability to access standard care resources, however, information on their pregnancy and neonatal outcomes is limited.ObjectiveTo assess risk of adverse pregnancy and neonatal outcomes among visually impaired women in Washington State from 1987 to 2014.MethodsWe conducted a retrospective cohort study using linked Washington State birth/fetal death hospital discharge records to compare outcomes among women with and without visual impairment noted at their delivery hospitalization. Pregnancy conditions and outcomes evaluated included gestational diabetes, pre-eclampsia, labor induction and cesarean delivery. Neonatal outcomes included preterm delivery and birth weight <2500 g. We assessed length of maternal and infant delivery hospitalization. We performed Poisson regression to estimate relative risks (RR) and 95% confidence intervals (CIs) for each outcome, adjusting for year of delivery, maternal age, and parity.ResultsMost adverse pregnancy and neonatal outcomes were similar for visually impaired (N = 232) and comparison women (N = 2362). However, visually impaired women had increased risks of severe pre-eclampsia (RR 3.77, 95% CI 1.69–8.43), labor induction (RR 1.33, 95% CI 1.10–1.61) and preterm delivery (RR 1.60, 95% CI 1.06–2.42). They were also more likely to have delivery hospitalizations of 3 or more days following a vaginal (RR 1.86, 95% CI 1.41–2.47). Among cesarean deliveries, infants of visually impaired women had increased risk (RR 1.24, 95% CI 1.02–1.51) of hospitalization for 3 or more days postpartum.ConclusionOur findings may be useful for obstetric providers in counseling their visually impaired patients.     

The effect of regular leisure physical activity on birth outcomes

Objectives: The purpose of this study was to determine the effect of regular leisure physical activity (RLPA) on two different adverse birth outcomes: timeliness of delivery (<37 weeks, preterm; 37–42 weeks, term; and >42 weeks, postterm) and low birth weight (<1500 g, very low; 1500–2499 g, low). Methods: The present sample, consisting of 9089 women, was obtained from the 1988 National Maternal and Infant Health Survey (NMIHS) data. The NMIHS was developed to examine adverse birth outcomes by assessing various maternal characteristics such as demographic, behavioral, and health care factors not found in vital statistics data. Results: The specified adjusted models obtained by logistic regression indicate that women who failed to engage in RLPA before and during their pregnancy were more likely to give birth to a very low birth weight baby [OR = 1.75; 95% CI (1.50, 2.04)] but not to a low birth weight baby [OR = 1.15; 95% CI (0.99, 1.34)] compared with women who remained active before and during pregnancy. Moreover, previously active women who stopped physical activity during pregnancy were more likely to give birth to a low birth weight [OR = 1.28; 95% CI (1.05, 1.56)] or a very low birth weight [OR = 2.05; 95% CI (1.69, 2.48)] baby than women who remained active before and during pregnancy. There was no significant relationship between RLPA and timeliness of delivery. Similar results were found after controlling for maternal medical risk. Conclusions: RLPA during pregnancy had no deleterious effect on birth outcomes among these women. RLPA may also reduce the risk of low birth weight outcomes.     

Predictors of Health Care Seeking Behavior During Pregnancy,Delivery, and the Postnatal Period in Rural Tanzania

Objectives Four antenatal visits, delivery in a health facility, and three postnatal visits are the World Health Organization recommendations for women to optimize maternal health outcomes. This study examines maternal compliance with the full recommended maternal health visits in rural Tanzania with the goal of illuminating interventions to reduce inequalities in maternal health. Methods Analysis included 907 women who had given birth within two years preceding a survey of women of reproductive age. Multinomial logistic regression was used to assess the influence of maternal, household, and community-level characteristics on four alternative classes defining relative compliance with optimal configuration of maternal health care seeking behavior. Results Parity, wealth index, timeliness of ANC initiation, nearest health facility type, religion, and district of residence were significant predictors of maternal health care seeking when adjusted for other factors. Multiparous women compared to primiparous were less likely to seek care at the high level [RRR 0.16, 95 % confidence interval (CI) 0.06–0.46], at the mid-level (RRR 0.22, 95 % CI 0.09–0.58), and the mid-low level (RRR 0.27, 95 % CI 0.09–0.80). Women in the highest wealth index compared to those in the poorest group were almost three times more likely to seek the highest two levels of care versus the lowest level (high RRR 2.92, 95 % CI 1.27–6.71, mid-level RRR 2.71, 95 % 1.31–5.62). Conclusion Results suggest that efforts to improve the overall impact of services on the continuum of care in rural Tanzania would derive particular benefit from strategies that improve maternal health coverage among multiparous and low socioeconomic status women.     

US Provider-Reported Diet and Physical Activity Counseling to Pregnant and Non-pregnant Women of Childbearing Age During Preventive Care Visits

Healthy diet, physical activity and appropriate weight gain during pregnancy contribute to healthy birth outcomes. The Institute of Medicine recommends that women receive counseling about diet and exercise during preconception, pregnancy and postpartum periods. We sought to determine how often healthcare providers report counseling women of childbearing age about diet or exercise and if such rates vary by pregnancy, overweight/obesity status or physician specialty. We combined the 2005–2010 National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey to obtain nationally representative estimates of outpatient preventive care visits for women of child-bearing age (15–44 years). Accounting for survey design, we compared proportions of preventive visits that included diet/exercise counseling for pregnant women versus non-pregnant women and performed multivariable logistic regression models to estimate odds ratios. Providers reported counseling pregnant women about diet/exercise during 17.9 % of preventive care visits compared to 22.6 % of visits for non-pregnant women (P < 0.01, adj. OR 0.8, 95 % CI 0.7, 1.0). Overweight/obese pregnant (vs. non-pregnant) women were significantly less likely to receive diet/exercise counseling (adj. OR 0.7, CI 0.5, 0.9) as were women seen by OB/GYNs versus non-OB/GYNs (adj. OR 0.4, CI 0.3, 0.5). Our findings suggest that provider-reported diet/exercise counseling rates during preventive care visits for women of childbearing age vary by overweight/obesity and pregnancy statuses, as well as by provider specialty. Our data suggest that there may be missed opportunities to provide diet/exercise counseling and that increasing rates of counseling could result in improved maternal and infant health outcomes.     

Use of maternal health services: comparing refugee,immigrant and US-born populations

Objectives To determine use of recommended maternal healthcare services among refugee and immigrant women in a setting of near-universal insurance coverage. Methods Refugee women age ≥18 years, who arrived in the US from 2001 to 2013 and received care at the same Massachusetts community health center, were matched by age, gender, and date of care initiation to Spanish-speaking immigrants and US-born controls. The primary outcome was initiation of obstetrical care within the first trimester (12 weeks gestation). Secondary outcomes were number of obstetrical visits and attending a postpartum visit. Results We included 375 women with 763 pregnancies (women/pregnancies: 53/116 refugee, 186/368 immigrant, 136/279 control). More refugees (20.6 %) and immigrants (15.0 %) had their first obstetric visit after 12 weeks gestation than controls (6.0 %, p < 0.001). In logistic regression models adjusted for age, education, insurance, BMI, and median census tract household income, both refugee (odds ratio [OR] 4.58, 95 % confidence interval [CI] 1.73–12.13) and immigrant (OR 2.21, 95 % CI 1.00–4.84) women had delayed prenatal care initiation. Refugees had fewer prenatal visits than controls (median 12 vs. 14, p < 0.001). Refugees (73.3 %) and immigrant (78.3 %) women were more likely to have postpartum care (controls 54.8 %, p < 0.001) with differences persisting after adjustment (refugee [OR 2.00, 95 % CI 1.04–3.83] and immigrant [OR 2.79, 95 % CI 1.72–4.53]). Conclusions for Practice Refugee and immigrant women had increased risk for delayed initiation of prenatal care, but greater use of postpartum visits. Targeted outreach may be needed to improve use of beneficial care.     

Transitions in Smoking Across a Pregnancy: New Information from the Growing Up in New Zealand Longitudinal Study

Introduction Maternal smoking remains a modifiable cause of adverse maternal and child health outcomes. This study investigated smoking transitions across pregnancy. Methods Data from the contemporary child cohort study Growing Up in New Zealand (n?=?6822) were used to analyse smoking status across three points across a pregnancy: pre-pregnancy, during pregnancy and after pregnancy. Odds-ratios (OR) were calculated for maternal, socio-economic and pregnancy-related factors associated with each transition using multivariate logistic regression. Results The prevalence of smoking pre-pregnancy was 20.3%. The cessation rate during pregnancy was 48.5%, while the postpartum relapse rate was 36.0%. Heavy smokers were less likely to quit during pregnancy (OR 0.13, 95% CI 0.08–0.20), and more likely to relapse at 9 months (OR 2.63, CI 1.60–4.32), relative to light smokers. Women in households with another smoker were less likely to quit during pregnancy (OR 0.35, CI 0.25–0.48), and more likely to relapse postpartum (OR 2.00, CI 1.14–3.51), relative to women in a smoke-free household. Women without high school qualifications were less likely to quit during pregnancy than women with bachelor degrees (OR 0.21, CI 0.11–0.41) but no more likely to relapse. Maori women were less likely to quit during pregnancy than European women (OR 0.35, CI 0.25–0.49) but no more likely to relapse. Conclusion Heavy smokers and those with another smoker in the household are at high risk of smoking during pregnancy or relapsing after pregnancy. Decreasing smoking across a pregnancy therefore requires a focus on cessation in all households with heavy smokers of child-bearing age. The association between smoking and ethnicity may be confounded as it not consistent across the pregnancy.     

Utilization of Maternal Health Care Among Immigrant Mothers in New York City, 2016–2018

Immigrant women represent half of New York City (NYC) births, and some immigrant groups have elevated risk for poor maternal health outcomes. Disparities in health care utilization across the maternity care spectrum may contribute to differential maternal health outcomes. Data on immigrant maternal health utilization are under-explored in the literature. We conducted a cross-sectional analysis of the population-based NYC Pregnancy Risk Assessment Monitoring System survey, using 2016–2018 data linked to birth certificate variables, to explore self-reported utilization of preconception, prenatal, and postpartum health care and potential explanatory pathways. We stratified results by maternal nativity and, for immigrants, by years living in the US; geographic region of origin; and country of origin income grouping. Among immigrant women, 43% did not visit a health care provider in the year before pregnancy, compared to 27% of US-born women (risk difference [RD] = 0.16, 95% CI [0.13, 0.20]), 64% had no dental cleaning during pregnancy compared to 49% of US-born women (RD = 0.15, 95% CI [0.11, 0.18]), and 11% lost health insurance postpartum compared to 1% of US-born women (RD = 0.10, 95% CI [0.08, 0.11]). The largest disparities were among recent arrivals to the US and immigrants from countries in Central America, South America, South Asia, and sub-Saharan Africa. Utilization differences were partially explained by insurance type, paternal nativity, maternal education, and race and ethnicity. Disparities may be reduced by collaborating with community-based organizations in immigrant communities on strategies to improve utilization and by expanding health care access and eligibility for public health insurance coverage before and after pregnancy.Supplementary InformationThe online version contains supplementary material available at 10.1007/s11524-021-00584-5.     

Exploring the Link between Maternity Leave and Postpartum Depression

Objectives

Postpartum depression affects a substantial proportion of new mothers in the United States. Although most employed women return to paid work after birth, the association between duration of maternity leave and postpartum depression is unclear. We therefore aimed to explore this relationship among mothers in the United States.

Physical Activity and Health-Related Quality of Life During Pregnancy: A Secondary Analysis of a Cluster-Randomised Trial

The aim of the study was to evaluate the role of physical activity before and during pregnancy on health-related quality of life (HRQoL). Data from the cluster-randomised gestational diabetes mellitus primary prevention trial conducted in maternity clinics were utilised in a secondary analysis. The cases considered were pregnant women who reported engaging in at least 150 min of moderate-intensity leisure-time physical activity per week (active women) (N = 80), and the controls were women below these recommendations (less active) (N = 258). All participants had at least one risk factor for gestational diabetes mellitus. Their HRQoL was evaluated via the validated generic instrument 15D, with HRQoL at the end of pregnancy examined in relation to changes in physical activity during pregnancy. Logistic regression models addressed age, parity, education, and pre-pregnancy body mass index. At the end of pregnancy, the expected HRQoL was higher (tobit regression coefficient 0.022, 95 % CI 0.003–0.042) among active women than less active women. Active women also had greater mobility (OR 1.98, 95 % CI 1.04–3.78), ability to handle their usual activities (OR 2.22, 95 % CI 1.29–3.81), and vitality (OR 2.08, 95 % CI 1.22–3.54) than did less active women. Active women reported higher-quality sleep (OR 2.11, 95 % CI 1.03–4.30) throughout pregnancy as compared to less active women. Meeting of the physical activity guidelines before pregnancy was associated with better overall HRQoL and components thereof related to physical activity.     

Maternal occupation and adverse pregnancy outcomes: a Finnish population-based study

BACKGROUND: There is accumulating evidence that the type of work and environmental exposures in the working environment may have adverse effects on foetal development. AIM: To compare the risk of low birth weight (LBW), small-for-gestational age (SGA) and pre-term delivery (PD) in broad categories of maternal occupation including farming and forestry; factory, mining and construction; office, non-manual and service work and housewives. METHODS: The study population consisted of 2568 singleton newborns of women who participated in The Finnish Prenatal Environment and Health Study after the delivery (response rate 94%). Information on maternal occupation and work during pregnancy was collected after the delivery. The health outcomes were LBW (<2500 g), SGA and PD (<37 weeks). RESULTS: In newborns of women working in factories, mining and construction, the risk of LBW (adjusted odds ratio [OR] 3.66, 95% confidence interval [CI] 1.15-11.62), SGA (adjusted OR 1.53, 95% CI 0.73-3.21), but not the risk of PD (adjusted OR 0.64, 95% CI 0.19-2.22), was higher compared with newborns of housewives. In newborns of farmers and forestry workers, the risks of PD (adjusted OR 2.38, 95% CI 1.01-5.65), LBW (adjusted OR 2.86, 95% CI 0.78-11.58) and SGA (adjusted OR 1.51, 95% CI 0.62-3.65) were all elevated. In office, non-manual and service workers, the corresponding estimates were lower (LBW: 1.62, 0.67-3.95; SGA: 1.45, 0.92-2.28; PD: 1.18, 0.69-2.01). CONCLUSIONS: There were substantial differences in the risk of adverse pregnancy outcomes between the main branches of industry.
