Changes in blood pressure and body weight following smoking cessation in women.

Objective.  Few have studied the long‐term effects of smoking and smoking cessation on weight gain and blood pressure increase and compared with the age‐related increases experienced by most adults. This study compared the development of weight and blood pressure in female never smokers, continuing smokers and smokers who quit smoking.

Social capital, institutional (vertical) trust and smoking: a study of daily smoking and smoking cessation among ever smokers.

Objectives: The associations between vertical (institutional) trust in the healthcare system and the mass media (newspapers and television), and daily smoking and smoking cessation were investigated. Methods: The 2004 public-health survey in Scania is a cross-sectional study. A total of 27,757 persons aged 18—80 years answered a postal questionnaire, which represents 59% of the random sample. A logistic regression model was used to investigate the associations between institutional trust in the healthcare system and the mass media, and daily smoking and smoking cessation. A multivariate analysis was performed to investigate the importance of possible confounders (age, country of origin, education, economic stress, generalized trust in other people) on the differences in daily smoking and smoking cessation according to trust in the healthcare system and the mass media. Results: 14.9% of the men and 18.1% of the women were daily smokers. Middle-aged respondents were daily smokers to a significantly higher extent than the young. Respondents with low trust in the healthcare system had significantly higher odds ratios of daily smoking, 1.88 (95% CI 1.38—2.57) among men and 2.05 (95% CI 1.51—2.78) among women, while respondents with low trust in the mass media had no significant odds ratios of daily smoking, 1.01 (0.67—1.52) among men and 1.55 (0.97—2.47) among women, after multiple adjustments. Conclusions: Institutional (vertical) trust in the healthcare system but not the mass media was significantly associated with lower odds of daily smoking and higher odds of having quit smoking if ever smoker. The healthcare system seems to be a potent arena for tobacco prevention.

Who are the "quitters"? a cross-sectional study of circumstances associated with women giving up smoking.

Background: Smoking is an important preventable risk factor for cardiovascular disease, cancer, and many other diseases. Even though tobacco consumption is declining in Sweden, it is not declining in all groups. This study explored socioeconomic and psychosocial circumstances hindering or facilitating smoking cessation in three birth cohorts of women from the general population. Methods: Between 1991 and 1996 a comprehensive questionnaire was administered to 17,319 women, 45—73 years old, from the Malmö Diet and Cancer cohort. Smoking habits were compared in relation to socioeconomic and psychosocial circumstances in three birth cohorts. Results: Of these women, 44% were never smokers, 28% were ex-smokers, and 28% were smokers (regular or occasional). When compared with smokers, ex-smokers were more often married, had a higher socioeconomic position, a longer education, more smoke-free surroundings, better emotional support, higher BMI, and better self-perceived health. Ex-smokers reported less work-related stress and less shift work. A history of cardiovascular disease was not associated with smoking cessation. The socioeconomic differences between current and former smokers were higher for young women as compared with older birth cohorts. Conclusions: Continuing smokers and quitters differ with regard to socioeconomic and psychosocial circumstances and factors related to working life and environmental tobacco exposure. By determining who the quitters are through continued follow-up, useful insights can be gained to develop strategies to achieve successful cessation of smoking.

COHb% as a marker of cardiovascular risk in never smokers: Results from a population-based cohort study

Aim: Carbon monoxide (CO) in blood as assessed by the COHb% is a marker of the cardiovascular (CV) risk in smokers. Non-smokers exposed to tobacco smoke similarly inhale and absorb CO. The objective in this population-based cohort study has been to describe inter-individual differences in COHb% in never smokers and to estimate the associated cardiovascular risk. Methods: Of the 8,333 men, aged 34—49 years, from the city of Malmö, Sweden, 4,111 were smokers, 1,229 ex-smokers, and 2,893 were never smokers. Incidence of CV disease was monitored over 19 years of follow up. Results: COHb% in never smokers ranged from 0.13% to 5.47%. Never smokers with COHb% in the top quartile (above 0.67%) had a significantly higher incidence of cardiac events and deaths; relative risk 3.7 (95% CI 2.0—7.0) and 2.2 (1.4—3.5), respectively, compared with those with COHb% in the lowest quartile (below 0.50%). This risk remained after adjustment for confounding factors. Conclusion: COHb% varied widely between never-smoking men in this urban population. Incidence of CV disease and death in non-smokers was related to COHb%. It is suggested that measurement of COHb% could be part of the risk assessment in non-smoking patients considered at risk of cardiac disease. In random samples from the general population COHb% could be used to assess the size of the population exposed to second-hand smoke.

Tobacco and myocardial infarction in middle-aged women: a study of factors modifying the risk.

Background.  Although myocardial infarction (MI) is strongly related to smoking, few have studied why some smokers are more vulnerable than others. This study explored how the risk of MI in current and former smokers is modified by other cardiovascular risk factors.

Incidence of myocardial infarction among Swedish and immigrant smoking women: Can physical activity modify the risk? An epidemiological study on the Malmö Diet and Cancer study

Background: Sweden has shown a decreasing tendency in the incidence of myocardial infarction (MI), except among middle-aged women. The incidence among middle-aged immigrant women is less explored. Aim: To determine if foreign-born women have a higher risk of MI as compared to women born in Sweden. Furthermore, to examine if physical activity (PA) modifies the risk of MI regardless of immigration status and smoking habits. Methods: The Malmö Diet and Cancer Study was used for analyses. A total of 16,776 women aged 45–73 years participated. The mean follow-up time was 13.8±4 years. Results: Mean age was 57.4±7.9 years. No difference was found in incidence of MI between Swedish and immigrant women (p=0.72). For current smokers among Swedish women, the relative risk (RR) with no/low PA was 2.93 (95% CI 2.07–4.14) and with moderate/high PA, the RR was 2.21 (95% CI 1.61–3.03) with no/low PA-never smoker as the reference group. Among immigrant smoking women, the RR with no/low PA was 4.56 (95% CI 1.62–12.8) and with moderate/high PA, the RR was 3.27 (95% CI 1.21–8.84) with no/low PA-never smoker as the reference group. Conclusions: PA reduces the risk of MI in non-smokers as well as in smokers, regardless of immigration status. Furthermore, PA was even more beneficial for women born outside Sweden. Against this background, immigrant women ought to get special consideration and attention from both caregivers and public health workers.

Obesity in Somali migration women due to post migration dietary changes and decreasing self-esteem : a qualitative interview study on diet, knowledge ab out risk of heart disease, inactivity, body image and self-esteem

The last-decade incidence of myocardial infarction (MI) has diminished dramatically in most age groups but not in middle-aged women in Sweden. There has been a large influx of immigrants and it has been shown that immigrant women have a higher BMI and are less physically active than Swedish women. Thereby they have a higher risk for heart disease. The aim of the study was to examine post-migration dietary changes, and knowledge about risks for heart diseases among Somali women. Furthermore, to examine the women’s perceptions of body image, self-esteem, and their knowledge about the positive effect of physical activity. The qualitative research method was used and eight Somali women aged 40 years or more, who have lived in Sweden longer than ten years, were interviewed with the help of a semistructured questionnaire. The study revealed that Somali migrated women in Sweden had changed their diet and experienced weight increase. They reported low self-esteem and little motivation for physical activity. They understood that they had a higher risk for heart disease as compared to Swedish women and they had, in general, a preference for big body size. The women of this study are, in combination with other risk factors, at a high risk of myocardial infarction. They all revealed a general knowledge about the relationship between obesity and inactivity and enhanced risks for heart disease. They had a preference for a larger female body image. They expressed low self-esteem, loneliness, and alienation from society. It is important to address the health issue among migrant Somali women in Sweden, but since this study had few informants, larger studies and more science is needed to further investigate the problem.

Smoking as a determinant of the geographical pattern of cardiac events among women in an urban population

Background: Smoking is the major risk factor for cardiac events in younger women and is most common in groups with the least favourable socioeconomic circumstances. Objective: To assess to what extent geographical differences in the female incidence of myocardial infarction in the city of Malmö in Sweden can be accounted for by smoking and to what extent intra-urban variances of smoking are related to socioeconomic circumstances. Method: Area specific prevalences of smokers is based on a sample of 17,319 women, aged 45—73 years. A comprehensive score was used to rank the 17 residential areas in terms of socioeconomic circumstances. Incidence of myocardial infarction and death is based on official statistics 1989— 97. Results: The area-specific prevalence of female smokers, which ranged from 17.5 to 32.5%, was inversely related to the socioeconomic score in 45- to 54 and 55- to 64-year-olds, r=-0.65 (p<0.05) and -0.59 (p<0.05). No correlation was found for women above 65 years of age. The annual age-adjusted incidence of cardiac events in the residential areas, which ranged from 151 to 414 per 100,000 person years, was strongly related to the prevalence of smokers, r=0.75 (p<0.001). Conclusion: Between 50% and 60% of the intra-urban variance of the female incidence of myocardial infarction was accounted for by smoking in this urban population. The geographical pattern of smoking was strongly related to inferior socioeconomic circumstances.

Can physical activity be used as a tool to reduce depression in patients after a cardiac event? What is the evidence? A systematic literature study.

A reduction in the incidence of cardiovascular diseases (CVD) has been reported in the Western world, but post-infarction depression often occurs and is related to poor medical outcomes. The aim of this study was to examine the scientific literature by a systematic review, in order to find evidence for whether physical activity can be a tool to reduce depression in patients who have suffered a cardiac event. Three databases were systematically searched (PubMed, CINAHL, and Cochrane), and the GRADE protocol was used in combination with a revised Amstar-protocol for the systematic review. Scientific reports fitting the area were scarce. Finally, ten studies were included in this study: one meta-analysis, five randomized controlled trials, and four clinical trials. The results showed low to moderate evidence for the use of low to moderate levels of exercise as a tool to reduce depression in post-coronary artery event patients. This study concluded positive effects of physical activity as a tool to reduce depression in post-coronary artery event patients. Physiotherapists could be further involved in increasing physical activity after cardiac events. More studies are needed in the area.

Attitudes to and Experiences of Physical Activity among Migrant Women from Former Yugoslavia——a qualitative interview study about physical activity and its beneficial effect on heart health, in Malmö, Sweden

Background Many risk factors for heart disease can be reduced by lifestyle modifications such as physical activity, but the attitude to and the knowledge about the beneficial effect of physical activity vary among the population. Migrant women are reported to have a higher BMI and to be less physically active than the Swedish-born women. In order to motivate them to participate in physical activity it is necessary to understand that they are not a homogenous group, and thus their knowledge about, needs for, and attitude to physical activity have to be examined. Aim: The aim of the study was to explore structural and individual factors working either as barriers against or as motivation for a change towards higher levels of physical activity and a healthy lifestyle. Furthermore, the aim was to investigate if the migration had changed the womens level of physical activity and what would be required to increase it. Method Seven women from Bosnia living in Malmö, Sweden, were interviewed by means of a semi-structured interview guide. The data was analyzed using Burnards content analysis method. Results The findings were presented in two categories, namely, “barriers against physical activity” and “motivational factors for physical activity”. With regard to the category “barriers against physical activity”, the move to Sweden had led to losses and shifts in lifestyles for the women. The greatest lifestyle changes were reported among women who had moved from rural areas in Bosnia to urban areas in Sweden. They found it troublesome to reach the same activity level in Sweden and expressed a greater need to do so. Earlier negative experiences or no experiences at all, of performing physical activity, as well as the winter climate, were seen as obstacles to being active. All the women prioritized family, work, school, and club activities above physical activity. With respect to the category “motivational factors for physical activity”, it was found that physical activity could help improve their mental balance, and the women also considered the possibility of losing weight. Conclusion The study showed that although these migrant women had difficulties finding appropriate and realistic physical activities, and prioritized family activities, they desired to be more physically active, even if the climate was seen as a hindrance. They also reported that physical activity could be a means to achieve better mental health as well as weight loss. Politicians ought to allocate funding, and public health worker to focus more on and enable this high risk group of immigrant women to become more physical active. They should also be informed about their increased risk of myocardial infarction. This, to stimulate increased physical activity among them and in ought to be in co-working with their own immigrant organization.
