Prevalence and socio-economic correlates of smoking among lone mothers in Australia

Cigarette smoking during breastfeeding in Papua New Guinea: Prevalence and demographic and socio-economic predictors

BACKGROUND

Cigarette smoking during breastfeeding is reported to contribute to significant changes in the composition of breast milk not only by reducing its protective features but also affecting infants' response to breastfeeding and breast milk. However, studies on the prevalence of cigarette smoking and associated factors during breastfeeding are limited in Papua New Guinea (PNG). This study estimates the prevalence of cigarette smoking and its association with demographic and economic factors among breastfeeding women in PNG.

METHODS

We used weighted survey data from the 2016-2018 PNG Demographic and Health Survey (PNGDHS). A weighted sample of 3,822 women who were breastfeeding during the survey were included in the study. The outcome variable in the present study is current cigarette smoking. A multiple logistic regression analysis was used to estimate the association between current cigarette smoking status and socio-demographic and economic variables of breastfeeding women. The regression analysis results were reported using adjusted odds ratios (aOR) with their respective 95% confidence intervals (CIs).

RESULTS

From the weighted sample, the prevalence of cigarette smoking among breastfeeding women was 21.9%; of which 60.8% smoked daily. The mean number of cigarettes smoked in the last 24 hours preceding the survey was 6.05(SD = 5.99). Multiple logistic regression analysis revealed that breastfeeding women who were from the Momase (aOR: 2.337, CI: 1.786-3.058, p<0.001) and Highlands (AOR: 1.589, CI: 1.213-2.082, p = 0.001), had no religious affiliation (aOR: 3.665, CI: 1.235-10.877, p = 0.019), and households with daughters as household heads (aOR: 1.901, CI: 1.231-2.935, p = 0.004) and being in more than one union (aOR: 2.374, CI: 1.805-3.123, p<0.001) were significantly more likely to smoke cigarette compared to women from southern region, those affiliated to Anglican church, those with husband as household heads, and being in one union respectively.

CONCLUSION

Cigarette smoking among breastfeeding women in PNG is relatively high, and region of residence, religion, relationship to household head, and the number of unions remain independent predictors. Interventions should target the individual socio-economic and cultural contexts within which breastfeeding occurs.

Maintenance of smoking cessation in Korean single mothers

BACKGROUND

Single mothers in South Korea are vulnerable to developing smoking habits, due to many difficulties and limitations; however, they have often been overlooked by smoking cessation support services. Therefore, this study aimed to investigate the general and smoking-related characteristics of single mothers registered with the Visiting a Smoking Cessation Service in Seoul, South Korea, to identify factors associated with smoking cessation maintenance at 4 weeks and 24 weeks after they initially quit smoking.

METHODS

The participants were 77 single mothers registered in the Smoking Cessation Service Program. Data were included from a three-year span (January 2017-December 2019). Smoking cessation counseling, motivational enhancement, and self-exploration counseling were provided for six months. The participants were evaluated on their smoking cessation status at 4 weeks and 24 weeks.

RESULTS

Most participants were aged 22 years or younger. The rates of smoking cessation maintenance were 58.4 and 18% at 4 weeks and 24 weeks, respectively. The higher the number of counseling sessions, the higher the participants' chances of maintaining smoking in all non-smoking periods, and whether pregnancy, CO level, and drinking were significant only in a short-term non-smoking period (4 weeks).

CONCLUSIONS

Our results suggest that the number of smoking cessation counseling sessions is important for long-term smoking cessation beyond short-term cessation in single mothers. To increase the smoking cessation rate of single mothers, it is important to conduct customized smoking cessation counseling at the time of smoking cessation and continue such counseling in the long term.

An Australian study of long-term hospital admissions and costs comparing patients with unintentional burns and uninjured people

BACKGROUND

The objective of this study was to describe and quantify the long-term hospital service use (HSU) after burn injury and associated costs in a population-based cohort of patients with unintentional burns and compare with uninjured people.

METHODS

This retrospective population-based cohort study analysed de-identified linked health administrative data of all unintentional burns patients (n = 10,460) between 2000 and 2012 in Western Australia and a matched uninjured comparison cohort (n = 42,856). HSU after burn injury (annual admission counts and cumulative length of stay) was examined. HSU costs were based on the Australian Refined Diagnosis Related Groups (AR-DRGs) code on each record. Generalised linear models were used to examine and quantify associations between burn injury and long-term HSU and associated costs.

RESULTS

There were 48,728 hospitalisations after burn occurring within the study period in the burn cohort; in the uninjured comparison cohort, there were 53,244 post-study index hospitalisations. Of those in the burn cohort, 63.9% (n = 6828) had a further hospitalisation after burn injury; this compared with 40.4% (n = 17,297) in the uninjured cohort. After adjustment for socio-demographic and pre-existing health conditions the burn cohort had 2.48 times the hospitalisation rate compared to the uninjured cohort (95% CI: 2.33-2.65). The cost of post-index hospitalisations in the burn cohort totalled to $AUS248.3 million vs $AUS240.8 million in the uninjured cohort. After adjustment, the burn cohort had hospital costs 2.77 times higher than the uninjured controls (95% CI: 2.58-2.98).

CONCLUSIONS

After adjustment for covariates, burn patients experienced greater hospital use for a prolonged period after the initial injury compared with uninjured people. The mean cost per episode of care was generally higher for members of the burn cohort compared to the uninjured cohort indicating either more complicated admissions or admissions for more expensive conditions.

Long-term mental health outcomes after unintentional burns sustained during childhood: a retrospective cohort study

Background

Burns are a devastating injury that can cause physical and psychological issues. Limited data exist on long-term mental health (MH) after unintentional burns sustained during childhood. This study assessed long-term MH admissions after paediatric burns.

Methods

This retrospective cohort study included all children (< 18 years) hospitalised for a first burn (n = 11,967) in Western Australia, 1980-2012, and a frequency matched uninjured comparison cohort (n = 46,548). Linked hospital, MH and death data were examined. Multivariable negative binomial regression modelling was used to generate incidence rate ratios (IRR) and 95% confidence intervals (CI).

Results

The burn cohort had a significantly higher adjusted rate of post-burn MH admissions compared to the uninjured cohort (IRR, 95% CI: 2.55, 2.07-3.15). Post-burn MH admission rates were twice as high for those younger than 5 years at index burn (IRR, 95% CI 2.06, 1.54-2.74), three times higher for those 5-9 years and 15-18 years (IRR, 95% CI: 3.21, 1.92-5.37 and 3.37, 2.13-5.33, respectively) and almost five times higher for those aged 10-14 (IRR, 95% CI: 4.90, 3.10-7.76), when compared with respective ages of uninjured children. The burn cohort had higher admission rates for mood and anxiety disorders (IRR, 95% CI: 2.79, 2.20-3.53), psychotic disorders (IRR, 95% CI: 2.82, 1.97-4.03) and mental and behavioural conditions relating to drug and alcohol abuse (IRR, 95% CI: 4.25, 3.39-5.32).

Conclusions

Ongoing MH support is indicated for paediatric burn patients for a prolonged period after discharge to potentially prevent psychiatric morbidity and associated academic, social and psychological issues.

A population-based comparison study of the mental health of patients with intentional and unintentional burns

Background

A number of studies report high prevalence of mental health conditions among burn patients. However there is a need to understand differences in the temporal relationship between mental health conditions and intentional and unintentional burns to hasten psychological prevention and intervention. This study aims to compare the socio-demographic profile, burn characteristics and pre- and post-burn psychiatric morbidity of burn patients by intent-of-injury.

Methods

De-identified linked hospital, death and mental health (MH) case registry data of burn patients hospitalised in Western Australia between 1 January 1980 and 30 June 2012 were analysed. Crude (observed) post-burn rates of mental health admissions were generated by burn intent-of-injury. Descriptive statistics were performed to compare the characteristics of the burn patients.

Results

A total of 30,997 individuals were hospitalised for a first burn; 360 (1.2%) had self-harm burns and 206 (0.7%) assault burns. Over the study period, admission rates for assault burns increased by 4.8% per year (95% confidence interval (CI) 3.1–6.5%) and self-harm burns increased 6.9% per year (95% CI 4.8–9.1%). Self-harm and assault burns occurred mainly among those aged 15 to 44 years (median age, interquartile range (IQR): self-harm 30 years, 22–40; assault 31 years, 23–38). Those with self-harm burns had a longer index hospital stay (median (IQR): self-harm 15 days (5–35) vs 4 days (1–11) assault vs 4 days (1–10) unintentional) and higher in-hospital mortality (7.2% self-harm vs 1.9% assault burns vs 0.8% unintentional). More than half (55.0%) of self-harm burns had a prior hospitalisation (5-year lookback) for a MH condition vs 10.7% of assault burns and 2.8% of unintentional burns. Crude post-burn rates of MH admissions per 100 person-years (PY) by intent-of-burn subgroups: self-harm 209 per 100 PY, assault burns 11 per 100 PY and unintentional burns 3 per 100 PY.

Conclusions

Intentional burn patients experienced significantly higher pre- and post-burn mental health morbidity along with significant adverse outcome in comparison with unintentional burns. Early psychological assessment and intervention could help in improving the MH of these patients.

How Social Care Beneficiaries in Poland Rate Relative Harmfulness of Various Tobacco and Nicotine-Containing Products

The aim of the study was to examine how social care beneficiaries rate the relative harmfulness of tobacco/nicotine-containing products compared to traditional cigarettes. This information is crucial for the development of effective tobacco control strategies targeting disadvantaged populations. The cross-sectional study covered 1817 respondents who were taking advantage of social aid services offered by the local social care institutions in the Piotrkowski district, via face-to-face interviews. The linear regression analysis indicated that relative to women, men consider slim cigarettes, smokeless tobacco and e-cigarettes to be more harmful than traditional cigarettes (p < 0.05). The smokers of traditional cigarettes reported menthol cigarettes to be less harmful than traditional cigarettes, relative to the non-smokers (p = 0.05). The current results demonstrate that social care beneficiaries are not aware of the fact that some products are less harmful than others. Education concerning tobacco/nicotine products should include advice on how to reduce the adverse health effects of smoking (e.g., avoiding inhalation of combusted products), while driving the awareness that no nicotine-containing products are safe.

Smoking Patterns and Smoking Cessation Willingness-A Study among Beneficiaries of Government Welfare Assistance in Poland

This study examines the prevalence and tobacco use patterns among adult social assistance beneficiaries and their interest in quitting. The results are based on data collected in a cross-sectional survey conducted among adults in the Piotrkowski district. A sample of 3636 social assistance beneficiaries produced a total of 1817 respondents who completed face-to-face questionnaires. Overall, 37.1% of the respondents, including 52.8% men and 29.6% women, were current smokers. Over one third of the smokers reported their willingness to quit. In the study population, several characteristics were significantly associated with the current daily smoking: male gender, low educational attainment, unemployment or temporary employment, lack of awareness of smoking-associated health risks, use of e-cigarettes, and exposure to environmental tobacco smoke (ETS). The intention to quit smoking among the daily smokers was positively correlated with their awareness of smoking-associated health risks, lack of previous quit attempts, and low exposure to ETS. Smoking prevalence among social assistance recipients tends to be higher than in the general population, but more than half of the smokers are willing to quit. There is an urgency to develop policies tailored to the needs of these disadvantaged population groups.

Burns and long-term infectious disease morbidity: A population-based study

BACKGROUND

There is a growing volume of data that indicates that serious injury suppresses immune function, predisposing individuals to infectious complications. With recent evidence showing long-term immune dysfunction after less severe burn, this study aimed to investigate post-burn infectious disease morbidity and assess if burn patients have increased long-term hospital use for infectious diseases.

METHODS

A population-based longitudinal study using linked hospital morbidity and death data from Western Australia for all persons hospitalised for a first burn (n=30,997) in 1980-2012. A frequency matched non-injury comparison cohort was randomly selected from Western Australia's birth registrations and electoral roll (n=123,399). Direct standardisation was used to assess temporal trends in infectious disease admissions. Crude annual admission rates and length of stay for infectious diseases were calculated. Multivariate negative binomial and Cox proportional hazards regression modeling were used to generate adjusted incidence rate ratios (IRR) and hazard ratios (HR), respectively.

RESULTS

After adjustment for demographic factors and pre-existing health status, the burn cohort had twice (IRR, 95% confidence interval (CI): 2.04, 1.98-2.22) as many admissions and 3.5 times the number of days in hospital (IRR, 95%CI: 3.46, 3.05-3.92) than the uninjured cohort for infectious diseases. Higher rates of infectious disease admissions were found for severe (IRR, 95%CI: 2.37, 1.89-2.97) and minor burns (IRR, 95%CI: 2.22, 2.11-2.33). Burns were associated with significantly increased incident admissions: 0-30days (HR, 95%CI: 5.18, 4.15-6.48); 30days-1year (HR, 95%CI: 1.69, 1.53-1.87); 1-10 years (HR, 95%CI: 1.40:1.33-1.47); >10years (HR, 95%CI: 1.16, 1.08-1.24). Respiratory, skin and soft tissue and gastrointestinal infections were the most common. The burn cohort had a 1.75 (95%CI: 1.37-2.25) times greater rate of mortality caused by infectious diseases during the 5-year period after discharge than the uninjured cohort.

CONCLUSIONS

These findings suggest that burn has long-lasting effects on the immune system and its function. The increase in infectious disease in three different epithelial tissues in the burn cohort suggests there may be common underlying pathophysiology. Further research to understand the underlying mechanisms are required to inform clinical interventions to mitigate infectious disease after burn and improve patient outcomes.

Burn leads to long-term elevated admissions to hospital for gastrointestinal disease in a West Australian population based study

BACKGROUND

While the most obvious impact of burn is on the skin, systemic responses also occur after burn, including intestinal inflammation. The objective of this study was to assess if burns are associated with increased long-term admissions for gastrointestinal diseases.

METHODS

A population-based longitudinal study using linked hospital morbidity and death data from Western Australia was undertaken of adults aged at least 15 years when hospitalized for a first burn (n=20,561) in 1980-2012. A frequency matched non-injury comparison cohort was randomly selected from Western Australia's birth registrations and electoral roll (n=80,960). Crude admission rates and summed days in hospital for digestive diseases were calculated. Negative binomial and Cox proportional hazards regression modeling were used to generate incidence rate ratios (IRR) and hazard ratios (HR), respectively.

RESULTS

After adjustment for demographic factors and pre-existing health status, the burn cohort had 1.54 times (95% confidence interval (CI): 1.47-1.62) as many admissions and almost three times the number of days in hospital with a digestive system diagnosis (IRR, 95% CI: 2.90, 2.60-3.25) than the uninjured cohort. Significantly elevated adjusted post-burn incident rates were identified, with the risk decreasing with increasing time: in the first month (HR, 95% CI: 3.02, 1.89-4.82), from one month to five years (HR, 95% CI: 1.42, 1.31-1.54), and from five to twenty years after burn (HR, 95% CI: 1.13, 1.06-1.20).

CONCLUSIONS

Findings of increased hospital admission rates and prolonged length of hospital stay for gastrointestinal diseases in the burn cohort provide evidence to support that burns have effects that persist long after the initial injury.

The impact of non-severe burn injury on cardiac function and long-term cardiovascular pathology

Severe burn injury significantly affects cardiovascular function for up to 3 years. However, whether this leads to long-term pathology is unknown. The impact of non-severe burn injury, which accounts for over 80% of admissions in developed countries, has not been investigated. Using a rodent model of non-severe burn injury with subsequent echocardiography we showed significantly increased left ventricular end systolic diameter (LVESD) and ventricular wall thickness at up to 3 months post-injury. Use of propranolol abrogated the changes in cardiac measures observed. Subsequently we investigated changes in a patient cohort with non-severe injury. Echocardiography measured at baseline and at 3 months post-injury showed increased LVESD at 3 months and significantly decreased posterior wall diameter. Finally, 32 years of Western Australian hospital records were used to investigate the incidence of cardiovascular disease admissions after burn injury. People who had experienced a burn had increased hospital admissions and length of stay for cardiovascular diseases when compared to a matched uninjured cohort. This study presents animal, patient and population data that strongly suggest non-severe burn injury has significant effects on cardiovascular function and long-term morbidity in some burn patients. Identification of patients at risk will promote better intervention and outcomes for burn patients.

Association between social capital and the prevalence of gestational diabetes mellitus: An interim report of the Japan Environment and Children's Study

BACKGROUND

Social capital is generally defined as the quality and frequency of social interactions with relatives, neighbors, and society. Social capital refers to broad concepts of social interactions and structures in individuals, communities and societies such as trust (e.g., neighborhood trust, which is social cohesion with neighbors) and social support (e.g., emotional support, which is the level of the feeling of being loved). Studies during the last few decades have shown that there is a significant inverse association between social capital and the prevalences of diseases such as depression and acute coronary syndrome. Significant inverse associations between trust, social support and the prevalence of diabetes have also been shown. However, associations between social capital and the prevalence of gestational diabetes mellitus (GDM) are less clear.

METHODS

We used the primary dataset of the Japan Environment and Children's Study (JECS), including 10,228 mothers with recorded obstetric outcomes from January to December 2011. In this study, we included 8874 the 10,228 participants. Diagnosis of GDM was determined using the criteria of the Japan Diabetes Society (JDS). The quality and quantity of social capital were measured with nine questions on a self-administered questionnaire during the second or third trimester. Using principal component analysis (PCA), we distinguished the following three components (indices) of social capital: (A) index of all nine questions about social capital, (B) index of emotional support and neighborhood trust and (C) index of generalized trust. The high factor loading variants of indices were as follows; (A) all nine variants, (B) five variants about emotional support and neighborhood trust and (C) two variants about generalized trust. Multivariate random effect modeling was used to calculate the odd ratios (ORs) for evaluating the association between these indices of social capital and the prevalence of GDM. This model was adjusted for baseline characteristics such as family income, BMI before pregnancy and smoking during pregnancy.

RESULTS

Of the 8874 participants, 204 women developed GDM (2.30%). Multivariable logistic regression analysis showed that index B, the index of emotional support and neighborhood trust (adjusted OR: 0.651, 95% CI: 0.429, 0.987) was significantly and independently associated with the prevalence of GDM.

CONCLUSIONS

We found that the 5-question index of emotional support and neighborhood trust is significantly associated with the prevalence of GDM during pregnancy.

Long-term musculoskeletal morbidity after adult burn injury: a population-based cohort study

OBJECTIVE

To investigate if adults who are hospitalised for a burn injury have increased long-term hospital use for musculoskeletal diseases.

DESIGN

A population-based retrospective cohort study using linked administrative health data from the Western Australian Data Linkage System.

SUBJECTS

Records of 17,753 persons aged at least 20 years when hospitalised for a first burn injury in Western Australia during the period 1980-2012, and 70,758 persons who were age and gender-frequency matched with no injury admissions randomly selected from Western Australia's electoral roll.

MAIN OUTCOME MEASURES

Admission rates and cumulative length of stay for musculoskeletal diseases. Negative binomial and Cox proportional hazards regression modelling were used to generate incidence rate ratios (IRR) and HRs with 95% CIs, respectively.

RESULTS

After adjustment for pre-existing health status and demographic characteristics, the burn cohort had almost twice the hospitalisation rate for a musculoskeletal condition (IRR, 95% CI 1.98, 1.86 to 2.10), and spent 3.70 times as long in hospital with a musculoskeletal diagnosis (95% CI 3.10 to 4.42) over the 33-year period, than the uninjured comparison cohort. Adjusted survival analyses of incident post-burn musculoskeletal disease admissions found significant increases for the 15-year post burn discharge period (0-6 months: HR, 95% CI 2.51, 2.04 to 3.11; 6 months-2 years: HR, 95% CI 1.77, 1.53 to 2.05; 2-15 years: HR, 95% CI 1.32, 1.23 to 1.42). Incident admission rates were significantly elevated for 20 years post-burn for minor and severe burn injury for a range of musculoskeletal diseases that included arthropathies, dorsopathies, osteopathies and soft tissue disorders.

CONCLUSIONS

Minor and severe burn injuries were associated with significantly increased post-burn incident admission rates, long-term hospital use and prolonged length of stay for a range of musculoskeletal diseases. Further research is required that facilitates identification of at-risk patients and appropriate treatment pathways, to reduce the long-term morbidity associated with burns.

Disadvantaged youth and smoking in mature tobacco control contexts: a systematic review and synthesis of qualitative research

OBJECTIVE

To review qualitative research and synthesise findings about socioeconomically disadvantaged and socially marginalised adolescents and young adults in mature tobacco control contexts.

DATA SOURCES

Searches of PubMed and MEDLINE, additional purposive searches in Google Scholar, PsycINFO, grey literature, specialist journals and reference lists for English language articles published after 2000. Search terms were qualitative, youth or adolescent or young adult, smoking/tobacco and vulnerable populations or disadvantage or socioeconomic inequality. The most recent update of the search was undertaken in January 2014.

STUDY SELECTION

Twenty articles, reporting on 17 studies, from 902 initial records were included. Inclusion criteria were: qualitative study undertaken in a country in the final stage of the tobacco epidemic and with comprehensive tobacco control measures in place, participants were youth who were socioeconomically disadvantaged or members of an identified subgroup with higher smoking prevalence and/or resided in a geographical area of low socioeconomic status. The target age range was 10-24.

DATA EXTRACTION

Data were independently extracted by one author, summarised and reviewed, compared and re-reviewed at multiple time points.

DATA SYNTHESIS

The majority of studies were from the UK, with the remainder from the USA, Australia and New Zealand. The review used a thematic analysis approach, and started with an open question: 'what does qualitative research tell us about disadvantaged young people and smoking?' The synthesis provides insights into the social context of smoking for marginalised and disadvantaged young people, group affiliation and identity, the role of smoking in social capital and sources of cigarettes.

CONCLUSIONS

Surprisingly few qualitative studies focused exclusively on smoking and disadvantaged young people were found. Future qualitative studies on the intersection between specific psychosocial characteristics associated with disadvantage and increased smoking risk would be of use to inform approaches to reduce socioeconomic differentials in smoking prevalence.

Are single mothers' higher smoking rates mediated by dysfunctional coping styles?

Background

Smoking prevalence has been shown to be considerably higher among single mothers as compared to their married or cohabiting counterparts. This study examines whether this could be attributed to single mothers’ different capability in dealing with stress.

Methods

Based on cross-sectional data of 3129 German mothers, the study explores the associations between single motherhood, coping styles and moderate and heavy smoking pattern using a regression-based ‘parallel multiple mediator model’.

Results

Single mothers showed higher rates of negative coping styles than partnered mothers, holding for ‘self-blame/rumination’ (p < 0.001), ‘blaming others’ (p = 0.048) and in particular for ‘substance consumption’ (p < 0.001). With respect to positive coping styles the findings were heterogeneous: while partnered mothers scored higher on ‘active influence’ (p < 0.001), single mothers showed higher values of ‘positive self-verbalisation’ (p < 0.001). Evidence for a mediating effect of coping styles on the relationship between single motherhood and moderate as well as heavy smoking was only found for ‘substance consumption’. Moreover, single motherhood may moderate the effect of ‘self-blame/rumination’ on heavy smoking (p = 0.025). Against expectations, higher levels of ‘active influence’ were not associated with lower but with significant higher odds of moderate smoking (OR = 1.19).

Conclusion

Single mothers compared to partnered mothers showed a different ability to cope with stress. However, only the coping strategy ‘substance consumption’ mediates the relationship between single motherhood and smoking. Exclusively in single mothers, ‘self-blame/rumination’ was associated with heavy smoking, indicating that they might utilize smoking as a way to come to terms with negative ruminative thoughts.

The effect of psychosocial stress on single mothers' smoking

Background

Evidence suggests an increased risk of smoking among single mothers as compared to their cohabitating counterparts. This article examines the role of psychosocial stress in mediating the relationship between single motherhood and smoking.

Methods

Data were derived from a cross-sectional population based sample of German women (n = 3129) with underage children (0–18 years of age). Perceived stress was measured with 13 items covering socioeconomic as well as family- and parenting-related stressors. According to Baron and Kenny (1986) a series of logistic regression models was applied to investigate the role of psychosocial stress as a mediator on the relationship between single motherhood and smoking.

Results

About 44.0% of single mothers smoked daily, whereas only 26.2% of cohabitating mothers did. Single mothers reported more stress related to their economic situation, occupation and family than partnered mothers. Out of the original 13 stressors only 'conflicts with the partner or ex-partner’ and 'financial worries’ remained significant in explaining single mothers’ higher risk of smoking. Against expectation, stress due to household requirements and family demands was associated with lower odds of single mothers’ smoking. After controlling for psychosocial stress, the odds ratio of single mothers’ moderate smoking (< 20 cig./day) decreased slightly from 1.75 to 1.66 (explained fraction XF = 12.0%) and with respect to heavy smoking (≥ 20 cig./day) more pronounced from 2.56 to 2.01 (XF = 35.3%).

Conclusions

It can be stated that single mothers’ heavy more than moderate smoking appeared to be mediated by perceived psychosocial stress. Out of all stressors considered, financial worries were of paramount significance in explaining single mothers’ heavy smoking while some family-related stressors rather appeared to keep single mothers from smoking. Overall, a higher stress exposure explains partly but not sufficiently single mothers’ increased smoking rates.

What has fairness got to do with it? Tackling tobacco among Australia's disadvantaged

ISSUE

While population wide smoking rates are falling steadily the rates remain high among the disadvantaged. The future we face is one where the differentials in smoking rates will continue to widen and will flow through to increased health inequalities.

APPROACH

How best to reduce smoking rates among the disadvantaged? Alongside existing population level initiatives and social policy initiatives is an urgent need for a targeted, comprehensive approach that acknowledges the serious impact of smoking on the disadvantaged. In 2006 Cancer Council NSW embarked on a statewide, multi-component Tackling Tobacco Program to encourage and support non-government social and community services to address smoking among their clients.

KEY FINDINGS

Tackling Tobacco Program results have shown that the 1600 staff from 400 organisations trained to provide smoking care can attain the knowledge and confidence to address tobacco and that clients are very receptive to receiving quit support from them. Improvements in quality of life for clients who do quit have been encouraging and the Tackling Tobacco Program has challenged assumptions and attitudes that disadvantaged people are uninterested and unable to quit.

IMPLICATIONS

Alongside population and social policy approaches must be a serious investment in tackling smoking among the disadvantaged.

CONCLUSIONS

Tackling Tobacco Program is an innovative example of how to engage disadvantaged smokers, de-normalise smoking and encourage and support quitting using familiar settings. Engaging Australia's large network of social and community services as allies in this work should be vigorously pursued.

Developing cessation interventions for the social and community service setting: a qualitative study of barriers to quitting among disadvantaged Australian smokers

Background

Smoking rates remain unacceptably high among individuals who are socially disadvantaged. Social and community service organisations (SCSO) are increasingly interested in providing smoking cessation support to clients, however little is known about the best way to assist disadvantaged smokers to quit in this setting. This study aimed to explore barriers and facilitators to quitting within the conceptual framework of the PRECEDE model to identify possible interventions appropriate to the social and community service setting.

Methods

Semi-structured focus groups were conducted with clients attending five community welfare organisations located in New South Wales, Australia. Thirty-two clients participated in six focus groups. A discussion guide was used to explore the barriers and facilitators to smoking and smoking cessation including: current smoking behaviour, motivation to quit, past quit attempts, barriers to quitting and preferences for cessation support. Focus groups were audio-taped, transcribed and analysed using thematic analysis techniques.

Results

Participants were current smokers and most expressed a desire to quit. Factors predisposing continued smoking included perceived benefits of smoking for stress relief, doubting of ability to quit, fear of gaining weight, and poor knowledge and scepticism about available quit support. The high cost of nicotine replacement therapy was a barrier to its use. Continual exposure to smoking in personal relationships and in the community reinforced smoking. Participants expressed a strong preference for personalised quit support.

Conclusions

Disadvantaged smokers in Australia express a desire to quit smoking, but find quitting difficult for a number of reasons. SCSOs may have a role in providing information about the availability of quit support, engaging disadvantaged smokers with available quit support, and providing personalised, ongoing support.

RCT of a client-centred, caseworker-delivered smoking cessation intervention for a socially disadvantaged population

BACKGROUND

Disadvantaged groups are an important target for smoking cessation intervention. Smoking rates are markedly higher among severely socially disadvantaged groups such as indigenous people, the homeless, people with a mental illness or drug and alcohol addiction, and the unemployed than in the general population. This proposal aims to evaluate the efficacy of a client-centred, caseworker delivered cessation support intervention at increasing validated self reported smoking cessation rates in a socially disadvantaged population.

METHODS/DESIGN

A block randomised controlled trial will be conducted. The setting will be a non-government organisation, Community Care Centre located in New South Wales, Australia which provides emergency relief and counselling services to predominantly government income assistance recipients. Eligible clients identified as smokers during a baseline touch screen computer survey will be recruited and randomised by a trained research assistant located in the waiting area. Allocation to intervention or control groups will be determined by time periods with clients randomised in one-week blocks. Intervention group clients will receive an intensive client-centred smoking cessation intervention offered by the caseworker over two face-to-face and two telephone contacts. There will be two primary outcome measures obtained at one, six, and 12 month follow-up: 1) 24-hour expired air CO validated self-reported smoking cessation and 2) 7-day self-reported smoking cessation. Continuous abstinence will also be measured at six and 12 months follow up.

DISCUSSION

This study will generate new knowledge in an area where the current information regarding the most effective smoking cessation approaches with disadvantaged groups is limited.

Do the wealthy have a health advantage? Cardiovascular disease risk factors and wealth

The use of wealth as a measure of socioeconomic status (SES) remains uncommon in epidemiological studies. When used, wealth is often measured crudely and at a single point in time. Our study explores the relationship between wealth and three cardiovascular disease (CVD) risk factors (smoking, obesity and hypertension) in a US population. We improve upon existing literature by using a detailed and validated measure of wealth in a longitudinal setting. We used four waves of data from the Panel Study of Income Dynamics (PSID) collected between 1999 and 2005. Inverse probability weights were employed to control for time-varying confounding and to estimate both relative (risk ratio) and absolute (risk difference) measures of effect. Wealth was defined as inflation-adjusted net worth and specified as a six category variable: one category for those with less than or equal to zero wealth and quintiles of positive wealth. After adjusting for income and other time-varying confounders, as well as baseline covariates, the risk of becoming obese was inversely related to wealth. There was a 40%-89% higher risk of becoming obese among the less wealthy relative to the wealthiest quintile and 11 to 25 excess cases (per 1000 persons) among the less wealthy groups over six years of follow up. Smoking initiation had similar but more moderate effects; risk ratios and differences both revealed a smaller magnitude of effect compared to obesity. Of the three CVD risk factors examined here, hypertension incidence had the weakest association with wealth, showing a smaller increased risk and fewer excess cases among the less wealthy groups. In conclusion, this study found a strong inverse association between wealth and obesity incidence, a moderate inverse association between wealth and smoking initiation and a weak inverse association between wealth and hypertension incidence after controlling for income and other time-varying confounders.

Effekte eines bindungstheoretisch fundierten Gruppenprogramms für alleinerziehende Mütter und ihre Kinder: PALME

Alleinerziehende Mütter und ihre Kinder sind erhöhten psychosozialen Belastungen und Gesundheitsrisiken ausgesetzt. Dennoch gibt es in Deutschland keine speziellen Hilfsangebote für diese Zielgruppe. Auf bindungstheoretischer Grundlage wurde ein emotionszentriertes Elterntraining (PALME; www.palme-elterntraining.de) für alleinerziehende Mütter mit Kindern im Vorschulalter entwickelt. Die Wirksamkeit des Trainings auf die Depressivität der Mütter, Mutter-Kind-Konflikte sowie kindliches Selbstbild und Problemverhalten wurde in einer randomisierten, kontrollierten Studie mit 61 alleinerziehenden, psychosozial mittelgradig belasteten Müttern untersucht. Es zeigten sich varianzanalytisch signifikante Gruppe x Messzeitpunkt-Interaktionseffekte zugunsten der Interventionsgruppe. Nach dem Training war die–teilweise klinisch ausgeprägte–maternale Depressivität im Mittel verbessert. Darüber hinaus ergaben sich Hinweise auf ein positiveres Selbstkonzept und tendenziell reduzierte Verhaltensprobleme ihrer Kinder.

Women and tobacco control policies: social-structural and psychosocial contributions to vulnerability to tobacco use and exposure

This article explores the psychosocial and social-structural vulnerability in relation to women's tobacco use, smoke exposure and responses to policy, and examines these issues in the context of women's lives and roles, describing forward looking strategies that could improve research and equity in outcomes for women. Various literatures on smoking among women and girls, and how women and sub-populations of women respond to tobacco control policies are reviewed. Specific sub-populations exhibiting more tobacco use and exposure are described, such as young pregnant and mothering women and low-income women. Emerging evidence also reveals links between smoking and experiences such as childhood sexual abuse, interpersonal violence, post-traumatic stress disorder, mental health issues and alcohol and drug dependence. Varied sub-populations of women respond in different ways to price and taxation, sales restrictions and location restrictions. However, tobacco control policies have, to date, been fashioned as broad instruments, not taking into account social context, trauma backgrounds, gendered roles such as mothering, unequal power relations affecting women in relationships and workplaces, and differences in access to resources and social support. When these issues are considered, the implications for tobacco policy development include: widening the policy purview, accounting for uneven and differential responses to policies, committing to an ethical framework, extending sex, gender and diversity based analyses, and improving research methods and approaches.

Parental smoking behavior and caries experience in preschool children

OBJECTIVES

The study aimed to explore the association between parental smoking behavior and caries experience in young children, taking into account the socioeconomic status and oral health-related behavior.

METHODS

Cross-sectional data from 1250 3-year-old and 1283 5-year-old children from four geographical areas in Flanders (Belgium) were analyzed. Children were examined at school by trained dentist-examiners, using standard criteria and calibrated examination methodology. Data on oral hygiene and dietary habits, oral health behavior, sociodemographic variables, and parental smoking behavior were obtained through structured questionnaires, completed by the parents.

RESULTS

Visible caries experience (i.e. d(3)mft > 0) was seen in 7% of 3-year olds and 31% of 5-year olds. In both age groups, 30% of the parents reported smoking behavior. Univariable logistic regression analysis with caries prevalence as the dependent variable, revealed that parental smoking was a significant independent variable. After controlling for age, gender, sociodemographic characteristics, oral hygiene, and dietary habits, the effect of family smoking status was no longer significant in 3-year-old children (OR = 1.98; 95% CI: 0.68-5.76). In 5-year olds the significant relationship between parental smoking behavior and caries experience persisted after adjusting for the other evaluated variables (OR = 3.36; 95% CI: 1.49-7.58).

CONCLUSION

The results of this study illustrate the existence of a significant association between parental smoking behavior and caries experience in 5-year-old children.

Single motherhood versus poor partner relationship: outcomes for antenatal mental health

OBJECTIVE

In the transition to parenthood, lack of social support significantly impacts on maternal mood. This paper compares the influence of single-mother status and level of partner support in a partnered relationship, on antenatal emotional health.

METHODS

Antenatal demographic, psychosocial and mental health data, as determined by Edinburgh Postnatal Depression Scale (EPDS) score, were collected from 1578 women. The association between these variables, and marital status, was investigated using logistic regression.

RESULTS

Sixty-two women (3.9%) were identified as single/unpartnered. Elevated EPDS scores (>12) were found in 15.2% (240/1578) of the total cohort and 25.8% (16/62) of the single/unpartnered women. EPDS scores were significantly lower for single/unpartnered women than for women with unsupportive partners (8.9+/-5.3 vs 11.9+/-6.5, p<0.001). Compared to the partnered cohort, single/unpartnered women were more likely to have experienced >or=2 weeks of depression before the current pregnancy (p<0.05), a previous psychopathology (p<0.001), emotional problems during the current pregnancy (p<0.01) and major life events in the last year (p<0.01). Binary logistic regression modelling to predict antenatal EPDS scores suggests that this is mediated by previous psychiatric history (p<0.001) and emotional problems during pregnancy (p=0.02).

CONCLUSION

Women in a partnered-relationship with poor partner-derived support were at an increased risk of elevated antenatal EPDS scores compared to single/unpartnered women. A previous history of depression and current emotional problems, rather than single mother status, were significant risk factors for elevated EPDS scores. The present study reiterates the contribution of psychosocial risk factors as important mediators of antenatal emotional health.

Tobacco policies and vulnerable girls and women: toward a framework for gender sensitive policy development

This article assesses the effects of comprehensive tobacco control policies on diverse subpopulations of girls and women who are at increased vulnerability to tobacco use because of disadvantage. The authors report on a recent assessment of experimental literature examining tobacco taxation; smoking location restrictions in public and private spaces; and sales restrictions. A comprehensive search was undertaken to identify relevant studies and evaluation reports. Gender based and diversity analyses were performed to identify pertinent sex differences and gender influences that would affect the application and impact of the policy. Finally, the results were contextualised within the wider literature on women's tobacco use and women's health. The authors consider not only the intended policy effects, but also explicitly examine the gendered and/or unintended consequences of these policies on other aspects of girls and women's health and wellbeing. A framework for developing gender sensitive tobacco programmes and policies for low income girls and women is provided.

The effect of single motherhood on smoking by socioeconomic status and race/ethnicity

We examined the association between parenting young children and smoking among US single women compared with married women, and whether this effect is moderated by socioeconomic status and race/ethnicity. Our main finding is that having children reduces smoking except among single white women, and women with low income. We used the Tobacco Use Supplement of the Current Population Survey, a nationally representative dataset (1995-96, n=70,019). Log-binomial regression analysis was used to estimate the association between parenting responsibility (i.e., presence of children aged 0-4 and 5-17) and daily smoking status, after taking into consideration marital status, income, and race/ethnicity. Single women faced a higher risk of smoking than married women. Parenting was protective against smoking among married women but not among single women. Additionally, among single women, the associations between parenting and smoking varied by income and race/ethnicity. Parenting increased the risk of smoking among single women in the lowest income quartile. Single black and Hispanic women with children had a risk of smoking similar to that of their childless counterparts. However, single white women with children were more likely to smoke than their childless counterparts. Smoking cessation interventions and programs to reduce environmental tobacco smoke should recognize that the co-occurrence of single motherhood, parenting responsibility and low-income may increase the risk of smoking. This is particularly significant given the rapid growth of the single women population, and their concentration in poverty in the USA. The finding that parenting is protective against smoking among single minority women, who presumably experience significant stressors, calls for a more thorough investigation of smoking behavior among minority women, and suggests the importance of stress buffers such as social support.

The effects of a multimodal intervention trial to promote lifestyle factors associated with the prevention of cardiovascular disease in menopausal and postmenopausal Australian women

The purpose of this study was to test the efficacy of a multimodal intervention (Women's Wellness Program) to improve women's cardiovascular risk factors. This 12-week randomized experiment with a control group targeted women 50-65 years living in the general population. Women in the intervention group were provided with a consultation with a registered nurse at which time biophysical cardiovascular risk measures were taken and health education was provided in both verbal and written form. Women were encouraged to review their smoking, nutrition, and water intakes and to commence an exercise program that included aerobic fitness exercises. Women in the control group continued their normal activities. The sample consisted of 90 women aged 50-65 years. Pre- and post-intervention assessment utilized seven measures of cardiovascular risk factors: waist-to-hip ratio (WHR), body mass index (BMI), blood pressure, heart rate, weight, exercise levels, and smoking. Analysis of covariance indicated that the intervention was effective in improving women's aerobic exercise activity and decreasing smoking. The data from all five biophysical outcome measures supported the efficacy of the intervention, with significant decreases seen in the women's WHR, BMI, blood pressure, and measured weight. Study implications suggest that this type of intervention may provide an effective, clinically manageable therapy for women who prefer a self-directed approach to preventing and decreasing cardiovascular risk factors.

Lone mothers are at higher risk for cardiovascular disease compared with partnered mothers. Data from the National Health and Nutrition Examination Survey III (NHANES III)

Lone mothers are a disadvantaged population, with research in several countries indicating that they experience low levels of physical and mental health. While research has demonstrated a socioeconomic gradient for cardiovascular disease (CVD), little research has explored lifestyle and clinical risk for CVD and prevalence of CVD events in lone mothers. The purpose of this study is (1) to compare select CVD lifestyle risks (smoking, obesity, physical activity), health, and relevant sociodemographic variables in partnered versus lone mothers; (2) to examine the relationship between partner status and having experienced a CVD event (myocardial infarction [MI], congestive heart failure [CHF], stroke). Data from the U.S. National Health and Nutrition Examination Survey III (NHANES III) included 1,446 women over 60 years with one or more children less than 17 years old. Lone mothers included women who were widowed, divorced, separated, never married, or married without the spouse living in the household (n = 623; weighted sample represents n = 3,904,450). Partnered mothers included women who reported living as married or married with the spouse in the household (n = 832; weighted sample represents n = 8,614,362). Weighted logistic regression was used to compare the prevalence of CVD risk factors in lone (43%) ver sus partnered (57%) mothers. Multivariate modeling was used to examine the relationship between partner status, CVD risks, and Coronary Heart Disease (CHD) events. Compared with partnered mothers, lone mothers were less educated and reported lower levels of income, health, and social support; and they were more likely to report non-White ethnicity. Lone mothers were more likely to be current smokers, overweight or obese, and physically active than partnered mothers. Those with clinical risks for CVD, including diabetes, elevated C-reactive protein, hypercholesterolemia, or hypertension, or all of these were more likely to be lone mothers. After adjusting for age, we found that mothers who had experienced a CVD event (MI, CHF, or stroke) were 3.3 times more likely to be a lone mother than a partnered mother (95% confidence interval (CI) 3.24, 3.31). Lone mothers are at increased risk for CVD. Health professionals and lone mothers should collaborate in the development of programs and policies not only to reduce lone mothers' risk for CVD, but also improve their conditions of living.

Ask your doctor: the construction of smoking in advertising posters produced in 1946 and 2004

This paper examines two full-page A3 poster advertisements in mass magazines produced at two time points over a 60-year period depicting smoking and its effects, with particular relation to lung cancer. Each poster represents the social and cultural milieu of its time. The writings of Foucault are used to explore the disciplinary technologies of sign systems as depicted in the two posters. The relationships between government, tobacco companies and drug companies and the technologies of production are examined with regard to the development of smoking cessation strategies. The technologies of power are associated with the constructions of risk and lifestyles. The technologies of the self locate smokers as culpable subjects responsible for their individual health. Finally, the meshing of these technologies places the doctor in the frame as "authoritative knower" and representative of expert systems.

Lone motherhood and risk for cardiovascular disease: the National Population Health Survey (NPHS), 1998-99

PURPOSE

To examine whether lone parenthood among Canadian women is associated with risk factors for cardiovascular disease (CVD).

METHODS

The sample was from the National Population Health Survey (NPHS) and it included 2,184 mothers (women with dependent children < 18 years of age) of whom 478 were lone (22%) and 1,706 (78%) were partnered mothers. Descriptive statistics and multiple logistic regression were undertaken with weighted data.

RESULTS

Compared to partnered mothers, lone mothers were significantly younger, and reported lower levels of education and income. Lone mothers reported significantly lower levels of health, less social support, and more distress and depression than partnered mothers. Further, lone mothers were significantly more likely to be smokers than partnered mothers. Odds ratios for being a lone mother and current smoker on social assistance in this analysis was 4.15 (95% CI 2.27-7.60), and for those reporting low or mid/high incomes respectively, were 2.99 (1.51-5.90) and 3.01 (1.93-4.70). There were no significant differences between the two groups for obesity or physical activity.

CONCLUSIONS

Smoking is a significant CVD lifestyle risk for lone mothers. Smoking occurred in the context of considerable life stress, depression, and distress pointing to links between health behaviour, psychosocial factors, and CVD health. These results suggest that lone mothers are a key target group for primary prevention in the CVD field. Programs and policies that support lone mothers in their goals of attaining healthier lifestyles have the potential to contribute to the prevention of cardiovascular disease in Canadian women.

Why is lone-motherhood so strongly associated with smoking?

OBJECTIVE

Lone mothers are among the most disadvantaged groups in many countries. Smoking prevalence among this demographic group is considerably higher than the general population. Previous work has shown that only part of this difference can be explained by age, not having a partner, living alone, and socio-economic factors. This study examined the contribution of mental health, the social environment, and the lifecourse in explaining the effect of lone motherhood on smoking status.

METHODS

Cross-sectional data from the 1995 National Health Survey and 2001 National Drug Strategy Survey were used. Smoking was defined as daily smoking. Mental health was assessed using a 14-item scale from the SF-36. Proportion of friends who smoke was used as an indicator of the social environment. Age started smoking daily (< or = 18 and > 18) was used as a lifecourse factor.

RESULTS

Mental health, proportion of friends who smoke and age of smoking initiation had strong associations with smoking status. However, they accounted for a small part of the association of being a lone mother and a smoker. After controlling for these factors, the odds of being a smoker among lone mothers were still twice those of mothers with partners (OR 2.1, 95% CI 1.7-2.7).

CONCLUSIONS AND IMPLICATIONS

Improving the socio-economic status (SES), mental health and the social environment of lone mothers could help reduce their high smoking prevalence. However, much of the effect of being a lone mother remains even after controlling for these factors. More research is needed to discover why prevalence is so high among this demographic group.
