Sociodemographic correlates of smoking in pregnancy and antenatal-care attendance in Indigenous and non-Indigenous women in South Australia

Perinatal outcomes of socially disadvantaged women in Australia: A population-based retrospective cohort study

OBJECTIVE

To examine the perinatal outcomes of women who experience social disadvantage using population-based perinatal data collected between 1999 and 2016.

DESIGN

Population-based, retrospective cohort study.

SETTING

Victoria, Australia.

POPULATION OR SAMPLE

A total of 1 188 872 singleton births were included.

METHODS

Cohort study using routinely collected perinatal data. Multiple logistic regression was performed to determine associations between social disadvantage and adverse maternal and neonatal outcomes with confidence limits set at 99%. Time-trend analysis for perinatal outcomes was performed in relation to area-level disadvantage measures.

MAIN OUTCOME MEASURES

Incidence of maternal admission to intensive care unit (ICU), postpartum haemorrhage (PPH) and caesarean section, perinatal mortality, preterm birth, low birthweight (LBW), and admission to special care nursery/neonatal intensive care unit (SCN/NICU).

RESULTS

Social disadvantage was associated with higher odds of adverse perinatal outcomes. Disadvantaged women were more likely to be admitted to ICU, have a PPH or experience perinatal mortality (stillbirth or neonatal death) and their neonates were more likely to be admitted to SCN/NICU, be born preterm and be LBW. A persistent social gradient existed across time for the most disadvantaged women for all outcomes except caesarean section.

CONCLUSIONS

Social disadvantage has a marked negative impact on perinatal outcomes. This aligns with national and international evidence regarding the impact of disadvantage. Strategies that improve access to, and reduce fragmentation in, maternity care in addition to initiatives that address the social determinants of health may contribute to improving perinatal outcomes for socially disadvantaged women.

The MOHMQuit (Midwives and Obstetricians Helping Mothers to Quit Smoking) Trial: protocol for a stepped-wedge implementation trial to improve best practice smoking cessation support in public antenatal care services

BACKGROUND

Smoking during pregnancy is the most important preventable cause of adverse pregnancy outcomes, yet smoking cessation support (SCS) is inconsistently provided. The MOMHQUIT intervention was developed to address this evidence-practice gap, using the Behaviour Change Wheel method by mapping barriers to intervention strategies. MOHMQuit includes systems, leadership and clinician elements. This implementation trial will determine the effectiveness and cost-effectiveness of MOHMQuit in improving smoking cessation rates in pregnant women in public maternity care services in Australia; test the mechanisms of action of the intervention strategies; and examine implementation outcomes.

METHODS

A stepped-wedge cluster-randomised design will be used. Implementation of MOHMQuit will include reinforcing leadership investment in SCS as a clinical priority, strengthening maternity care clinicians' knowledge, skills, confidence and attitudes towards the provision of SCS, and clinicians' documentation of guideline-recommended SCS provided during antenatal care. Approximately, 4000 women who report smoking during pregnancy will be recruited across nine sites. The intervention and its implementation will be evaluated using a mixed methods approach. The primary outcome will be 7-day point prevalence abstinence at the end of pregnancy, among pregnant smokers, verified by salivary cotinine testing. Continuous data collection from electronic medical records and telephone interviews with postpartum women will occur throughout 32 months of the trial to assess changes in cessation rates reported by women, and SCS documented by clinicians and reported by women. Data collection to assess changes in clinicians' knowledge, skills, confidence and attitudes will occur prior to and immediately after the intervention at each site, and again 6 months later. Questionnaires at 3 months following the intervention, and semi-structured interviews at 6 months with maternity service leaders will explore leaders' perceptions of acceptability, adoption, appropriateness, feasibility, adaptations and fidelity of delivery of the MOHMQuit intervention. Structural equation modelling will examine causal linkages between the strategies, mediators and outcomes. Cost-effectiveness analyses will also be undertaken.

DISCUSSION

This study will provide evidence of the effectiveness of a multi-level implementation intervention to support policy decisions; and evidence regarding mechanisms of action of the intervention strategies (how the strategies effected outcomes) to support further theoretical developments in implementation science.

Pregnant and postnatal women's experiences of interacting with health care providers about their tobacco smoking: a qualitative systematic review

OBJECTIVE

The objective of this review was twofold: (i) to comprehensively identify the best available evidence about the experiences of women who smoked tobacco during pregnancy or postnatally (or both) concerning health care providers' interactions with them about their smoking, when such interactions occurred during contact for prenatal or postnatal health care in any health care setting; and (ii) to synthesize the research findings for recommendations to strengthen health care providers' interventions regarding smoking during pregnancy and smoking during the postnatal period.

INTRODUCTION

Maternal tobacco smoking during pregnancy and maternal tobacco smoking postnatally pose serious health risks for the woman, fetus, and offspring, whereas maternal smoking cessation has beneficial health effects. Given the importance of health care providers' interactions with pregnant and postnatal women for smoking cessation care, it is essential to understand women's experiences of such interactions.

INCLUSION CRITERIA

Studies considered for this review had qualitative research findings about the experiences of women who smoked tobacco during pregnancy or postnatally (or both) in relation to health care providers' interactions with them about their smoking.

METHODS

The review was conducted using the JBI approach to qualitative systematic reviews. Published studies were sought through 6 academic databases (eg, CINAHL, MEDLINE). Unpublished studies were searched in 6 gray literature sources (eg, ProQuest Dissertations and Theses, Google Scholar). Reference lists of retrieved records were also searched. The searches occurred in October and November 2020; no country, language, or date limits were applied. Study selection involved title and abstract screening, full-text examination, and critical appraisal of all studies that met the inclusion criteria for the review. Study characteristics and research findings were extracted from the included studies. Study selection and extraction of findings were conducted by two reviewers independently; differences between reviewers were resolved through consensus. The research findings were categorized, and the categories were aggregated into a set of synthesized findings. The synthesized finding were assigned confidence scores. The categories and finalized synthesized findings were agreed upon by all reviewers.

RESULTS

The 57 included studies varied in qualitative research designs and in methodological quality (from mostly low to high). There were approximately 1092 eligible participants, and 250 credible and unequivocal research findings. The research findings yielded 14 categories and 6 synthesized findings with low to very low confidence scores. Some women who smoked tobacco during pregnancy and some women who smoked tobacco postnatally lacked supportive interactions by health care providers regarding their smoking; other women experienced supportive interactions by health care providers. Women were adversely impacted when health care providers' interactions lacked supportiveness, and were beneficially impacted when interactions were supportive. Women varied in openness to health care providers' interactions regarding their smoking, from not being receptive to being accepting, and some women wanted meaningful health care provider interactions.

CONCLUSIONS

Although confidence in the synthesized findings is low to very low, the evidence indicates that supportive health care provider interactions may facilitate positive smoking behavior change in pregnancy and postnatally. It is recommended that health care providers implement accepted clinical practice guidelines with women who smoke prenatally or postnatally, using an approach that is person-centered, emotionally supportive, engaging (eg, understanding), and non-authoritarian.

Indigenous Women's Experiences of Smoking and Quitting Smoking in Pregnancy: A Phenomenological Study

BACKGROUND

Maternal smoking during pregnancy (MSDP) is an important public health concern because of potential adverse health effects to the woman, fetus, and child after birth. Prevalence rates are high among groups with socioeconomic disadvantage, including Indigenous women.

PURPOSE

This study was conducted to understand experiences of MSDP for Indigenous women.

METHODS

The study was conducted using phenomenology. Data were collected through interviews with 15 pregnant and postnatal Indigenous women who had smoked during pregnancy. The data were analyzed for themes using phenomenological methods.

RESULTS

The women's narratives revealed four experiences: quitting smoking during pregnancy to protect the unborn baby from harm; quitting smoking during pregnancy because of personal adverse health effects; cutting down smoking during pregnancy and feeling remorse for not quitting; and keeping on smoking during pregnancy and not planning to try to quit. The women's experiences also indicated several impediments to quitting smoking.

CONCLUSIONS

There is need for health care policy to ensure adequate smoking cessation services and support for Indigenous women who smoke in pregnancy. Health care professionals should provide individualized interventions that take into account the challenges to quitting that pregnant women experience and that are in accordance with clinical practice guidelines for MSDP.

Knowledge, Attitude and Smoking Patterns Among Pregnant Women: A Jordanian Perspective

Background:

Smoking during pregnancy is one of the main modifiable factors associated with perinatal morbidity and mortality and maternal complications. Literature is scant regarding smoking habits of pregnant women in Jordan.

Objectives:

To investigate smoking patterns and attitudes of Jordanian pregnant women towards smoking.

Methods:

A cross-sectional survey of patterns and attitudes towards smoking among 436 mothers attending healthcare facilities in the Governorate of Irbid, Jordan, between August and September 2019.

Results:

Out of 436 pregnant women in the Governorate of Irbid, Jordan, 13 (2.9%) quit smoking once pregnancy was conformed, and 77 (17.6%) continued to smoke.

Pregnant non-smokers believed that hookah and electronic cigarettes are as bad to health as cigarettes, while smokers believed that hookah and electronic cigarettes are less hazardous than cigarettes (5.19% versus 21.99%, p = 0.001, and 6.49% versus 19.37%, p = 0.009, respectively).

Non-smokers were significantly more aware regarding the hazards of smoking on perinatal outcomes, such as abortion (31.94% versus 10.39%, p = 0.001), placental abruption (31.94% versus 10.39%, p = 0.001), intrauterine growth restriction and fetal malformations (36.65% versus 14.29%, p = 0.007), fetal death (30.89% versus 6.49, p < 0.001), neonatal pulmonary diseases (44.50% versus 24.68%, p = 0.024), neonatal asthma (47.12% versus 28.57%, p = 0.038), and ear diseases (42.41% versus 20.8%, p = 0.012).

Conclusion:

There is a high prevalence of smokers among pregnant women in Jordan. The level of awareness regarding long-term consequences of tobacco use remains low. Educational programs should include information about the hazards of all forms of smoking. Pregnancy provides a good opportunity for promoting smoking cessation.

Improving antenatal engagement for Aboriginal women in Australia: A scoping review

BACKGROUND

Aboriginal women have an increased risk of poor antenatal engagement in pregnancy in comparison with Caucasian women, due to inequalities in health care provision. The Pregnancy Outcome in South Australia reports Aboriginal women having 10 times the risk of non-attendance of antenatal care throughout their pregnancy, 3 times the risk of attending the initial booking appointment later than recommended in their pregnancy, and Aboriginal women have an increased risk of attending significantly less antenatal appointments than Caucasian women.

OBJECTIVE

The primary purpose of the scoping review is to map the body of literature known about Aboriginal women engaging with antenatal care in Australia, and the factors that facilitate or cause barriers to this engagement. Secondary to this, the review will describe how culturally safe care influences antenatal engagement.

METHODS

Scoping reviews utilise a broad range of literature, encompassing all types of studies. An online search of 6 databases was conducted to identify and critically analyse sources discussing antenatal engagement for Aboriginal women in Australia. Using the JBI framework for Scoping Reviews, the researcher was able to strengthen the rigour of the methodology.

FINDINGS

The search produced 9 articles, relating to 6 studies addressing antenatal engagement for Aboriginal women in Australia. Several themes were prevalent in the research that impact antenatal engagement including: Smoking, Relocation, Continuity of Care, Aboriginal maternity infant care workers, home visits, birthing on country, age, family and culturally safe care.

CONCLUSION

Aboriginal women have identified continuity of care, Aboriginal workforce, home visits, family involvement, birthing on country and cultural safety as factors that improve antenatal engagement. Aboriginal women have reported smoking, rural and remote location, cultural incompetence and young age as factors that deter them from engaging with antenatal care. In order to improve antenatal engagement for Aboriginal women in South Australia, culturally safe care is essential. In order to determine the factors that facilitate and/or deter Aboriginal women from antenatal engagement, further research is required.

Determining a strategy to reduce smoking in pregnancy

BACKGROUND

Further efforts, informed by current data, are needed to reduce smoking during pregnancy.

AIMS

To describe trends in smoking during pregnancy and identify regions most likely to benefit from targeted smoking cessation interventions, in New South Wales (NSW), Australia.

MATERIALS AND METHODS

All women who gave birth in NSW between 1994 and 2016 were included. Smoking status was identified from the Perinatal Data Collection. For births between 2012 and 2016, women were grouped into Local Health District (LHD) of residence, and smoking rates calculated. The impacts of a hypothetical smoking cessation intervention in four LHDs with (i) high smoking rates and (ii) high numbers of smokers, were compared.

RESULTS

The overall smoking rate during pregnancy decreased from 22.1% in 1994 to 8.3% in 2016. [Correction added on 13 August 2020, after first online publication: the overall smoking rate during pregnancy in 1994 has been corrected from 14.5% to 22.1%.]. The decrease was lowest among women living in the most socioeconomically disadvantaged areas (41%) and highest among those living in the most advantaged areas (83%). Between 2012 and 2016, over half the women who smoked during pregnancy lived in one of four LHDs. Only 1% of women reporting smoking during pregnancy resided in the LHD with the highest smoking rate (34.7%). A simulated intervention targeting only four regions showed greater effect on the statewide smoking rate when targeting LHDs with high numbers of smokers rather than high smoking rates.

CONCLUSIONS

Despite decreases in rates of smoking during pregnancy, there was evidence of geographic clustering of smokers. The greatest reduction in overall smoking may come from interventions targeting the four LHDs with the highest number of smokers.

Individual and Regional Characteristics Associated with Maternal Smoking During Pregnancy in Japan: Healthy Parents and Children 21

Smoking during pregnancy causes various maternal and fetal health problems. Although there are considerable differences in maternal smoking proportions between localities, only a few studies have investigated the effects of regional characteristics on maternal smoking behavior. This study aimed to clarify the association between maternal smoking during pregnancy and individual and regional characteristics. We used data from a large nationwide birth cohort study in Japan that consisted of information on 20,267 women with children aged 3–4 months. The multilevel regression model was used to examine the association between smoking behavior during pregnancy and individual and regional characteristics. On multilevel analysis, late birth order, young age of the mother at birth, low birth weight, low economic status, husband’s smoking during pregnancy, maternal alcohol consumption during pregnancy, absence of a pregnancy counselor, and lack of participation in local events for childrearing were significantly associated with maternal smoking behavior during pregnancy at the individual level. Meanwhile, a high unemployment rate and a high number of nurseries were significantly associated with maternal smoking behavior during pregnancy at the regional level. In conclusion, we showed the relation between maternal smoking during pregnancy and the individual- and regional-level characteristics.

Using Facebook to reduce smoking among Australian Aboriginal and Torres Strait Islander people: a participatory grounded action study

BACKGROUND

There is limited evidence for the effectiveness of social media to promote healthy behaviour among Indigenous Australians, including to reduce smoking. Social media has significant potential to stimulate interpersonal influence to quit, however an important knowledge gap is how and what content people choose to share with friends and family. This paper explores the decision making processes of community members for sharing tobacco control content with family and friends on Facebook.

METHODS

Community researchers were paid to choose and share at least one tobacco control post per week for a period of 6 months on their personal Facebook page. They documented reasons for their choices, which were coded and analysed to determine features of messages most likely to be shared, and salient considerations in the decision-making process.

RESULTS

Posts which are child-focused, feature Indigenous content, and are perceived as practical, relevant and credible, with a direct and unambiguous message, were most likely to be shared. Posts which included disgusting imagery about health impacts, were focused on the environment, or were ambiguous or sarcastic were less likely to be shared. Decisions were also based on whether content was perceived to contain new information, to be helpful for their friends, and to be consistent with the participant's online identity, as well as the perceived sensitivity of content. The potential impact on expensive mobile data for videos was also a factor.

CONCLUSIONS

When designing tobacco control messages to be shared on social media, health promoters should take into account how information will align with positive self-image and can contribute to social capital among the intended audience, and generate interpersonal engagement. Content should complement, rather than attempt to replicate, some message features that are effective on traditional broadcast media. This study shows the potential for health services to incorporate a strategy of using paid local social media 'champions' or 'ambassadors' to disseminate tobacco control messages on Facebook through community networks.

What are the costs associated with child and maternal healthcare within Australia? A study protocol for the use of data linkage to identify health service use, and health system and patient costs

INTRODUCTION

The current literature in Australia demonstrates that there are variations in access and outcomes in perinatal care based on socioeconomic factors. However, little has been done looking at the level of out-of-pocket healthcare costs associated with perinatal care. The primary aim of this project will be to quantify health service use and out-of-pocket healthcare expenditure associated with childbearing and early childhood in Queensland, Australia.

METHODS AND ANALYSIS

This project will build Australia's first model (called Maternal & Child Cost MOD) of out-of-pocket healthcare expenditure by using administrative data from the Queensland Perinatal Data Collection, of all childbearing women and their resultant children, who gave birth in Queensland between 1 July 2012 and 30 June 2016.The current costs to the health system and out-of-pocket health care expenditure of patients associated with maternity and early childhood health care will be identified. The differences in costs based on indigenous identification, socioeconomic status and geographic location will be assessed using linear regression modelling and counterfactual modelling techniques.

ETHICS AND DISSEMINATION
