Women's perceived and partners' reported support for smoking cessation during pregnancy.

Studies of the influence of social support on successful smoking cessation have been based on the smoker's perceptions only. In this pilot study of 58 couples, pregnant women who had smoked in the 30 days before pregnancy and their partners reported the positive and negative support for cessation they had received (women) or provided (partners). Mean levels of the women's and partners' perceptions of support were compared, and correlations of the two reports were analyzed while controlling for the effect of the couple's smoking status. Women's and partners' reports were similar except partners reported wanting the women to stop smoking more than women perceived. Women's and partners' perceived negative support were moderately correlated (r approximately equal to .48, p approximately equal to .001). Partner-reported positive support also was associated with women's perceived negative support (r approximately equal to .30, p approximately equal to .03). These relationships remained signif cant after controllingfor partners' and women's smoking status. Generally, partners reported giving more positive and less negative support than women perceived. Results suggest the need for further examination of couples' perceptions of support and the impact on smoking cessation during pregnancy.

Promoting smoking abstinence in pregnant and postpartum patients: a comparison of 2 approaches.

OBJECTIVE: To compare the implementation, delivery, and implications for dissemination of 2 different maternal smoking-cessation/relapse-prevention interventions in managed care environments. STUDY DESIGN: Healthy Options for Pregnancy and Parenting (HOPP) was a randomized, controlled efficacy trial of an intervention that bypassed the clinical setting. Stop Tobacco for OuR Kids (STORK) was a quasi-experimental effectiveness study of a point-of-service intervention. Both incorporated prenatal and postnatal components. PATIENTS AND METHODS: Subjects in both studies were pregnant women who either smoked currently or had quit recently. The major intervention in HOPP was telephone counseling delivered by trained counselors, whereas the STORK intervention was delivered by providers and staff during prepartum, inpatient postpartum, and well-baby visits. RESULTS: In HOPP, 97% of telephone intervention participants reported receiving 1 or more counselor calls. The intervention delayed but did not prevent postpartum relapse to smoking. Problems with intervention delivery related primarily to identification of the target population and acceptance of repeated calls. STORK delivered 1 or more cessation contacts to 91% of prenatal smokers in year 1, but the rate of intervention delivery declined in years 2 and 3. Modest differences were obtained in sustained abstinence between 6 and 12 months postpartum, but not in point prevalence abstinence at 12 months. CONCLUSIONS: The projects were compared using 4 of the 5 dimensions of the RE-AIM model including reach, adoption, implementation, and maintenance. It was difficult to apply the fifth dimension, efficacy, because of the differences in study design and purpose of the interventions. The strengths and limitations of each project were identified, and it was concluded that a combined intervention that incorporates elements of both HOPP and STORK would be optimal if it could be implemented at reasonable cost.

Tobacco, alcohol, and caffeine use and cessation in early pregnancy.

OBJECTIVES: Little is known about what happens when individuals attempt to make multiple behavior changes simultaneously. Pregnant women in particular are often in the position of needing to change several behaviors at once, including giving up more than one pleasurable substance. We investigated the success of pregnant women in spontaneously quitting tobacco, alcohol, or caffeine, alone or in combination. METHODS: Pregnant women (n = 7489) were identified in the practices of large health maintenance organizations in Seattle and Minneapolis and were interviewed by telephone. Analyses examined the patterns of using and quitting more than one substance, and the extent to which using more than one substance predicts ability to quit other substances. RESULTS: Use of the three substances tended to cluster within individuals. Users of multiple substances were less likely to quit each substance than users of single substances. However, in the subgroup of multiple substance users who had quit one substance, having quit a second substance was more, rather than less, common. In multivariate analyses predicting quitting, demographic variables, and not having been pregnant previously were significant predictors of quitting each substance; being a nonsmoker predicted quitting alcohol, and being a nonsmoker and nondrinker predicted quitting caffeine. CONCLUSIONS: The reasons for difficulty in quitting more than one substance are unknown but may include the difficulty of formulating appropriate behavioral strategies or less concern about healthy behavior in pregnancy. Many women in the study successfully quit using two substances, however, and counseling should focus on achieving that outcome.

Stress, depressive symptoms, and smoking cessation among pregnant women.

Perceived stress and depressive symptoms were examined as correlates and predictors of smoking cessation during pregnancy in a sample of 819 pregnant smokers (454 baseline smokers and 365 baseline quitters). Women who quit early in pregnancy had lower levels of stress and depressive symptoms than baseline smokers. Adjusting for level of addiction and other demographic factors related to stress and depressive symptoms eliminated the significant association between depressive symptoms and smoking cessation. Lower levels of stress and depressive symptoms were not predictive of cessation in later pregnancy. Prenatal healthcare providers should continue to assess level of addiction and provide targeted intensive cessation interventions. Interventions that reduce stress and depression may also be of benefit to women who are continuing smokers in early pregnancy.

Evaluation of a community-based program to improve infant immunization rates in rural Minnesota.

OBJECTIVE: The purpose of this study was to evaluate the effects of enrollment in a community-based public health nursing program, Communities Caring for Children (CCC), on infant immunization rates in rural Minnesota. The program involved health education, a registry, and a reminder system. DESIGN: The evaluation was a collaborative effort of university, public health agency, and private managed-care personnel. Two data sources were used to assess the association of program enrollment and immunization compliance; public birth certificates and a telephone survey of 421 CCC enrollees and non-enrollees. RESULTS: Birth certificate and survey data showed that CCC enrollees were significantly younger, less educated, more likely to be white, and of lower parity than non-enrollees. The average age of subjects' infants was eight months. The survey data showed that, overall, CCC enrollees perceived less danger in infant immunizations than did non-enrollees and were more likely than non-enrollees to have access to infant immunization reminder cards. CCC enrollees reported significantly higher immunization compliance for their infants than did non-enrollees. CONCLUSIONS: The area served by this program is relatively low-income and rural. Infant immunization status was among the lowest in Minnesota prior to the implementation of CCC. The evaluation suggested that enrollment in CCC was one of the most powerful predictors of infant immunization compliance.

Prevention of relapse in women who quit smoking during pregnancy.

OBJECTIVES: This study is an evaluation of relapse prevention interventions for smokers who quit during pregnancy. METHODS: Pregnant smokers at 2 managed care organizations were randomized to receive a self-help booklet only, prepartum relapse prevention, or prepartum and postpartum relapse prevention. Follow-up surveys were conducted at 28 weeks of pregnancy and at 8 weeks, 6 months, and 12 months postpartum. RESULTS: The pre/post intervention delayed but did not prevent postpartum relapse to smoking. Prevalent abstinence was significantly greater for the pre/post intervention group than for the other groups at 8 weeks (booklet group, 30%; prepartum group, 35%; pre/post group, 39%; P = .02 [different superscripts denote differences at P < .05]) and at 6 months (booklet group, 26%, prepartum group, 24%; pre/post group, 33%; P = .04) postpartum. A nonsignificant reduction in relapse among the pre/post group contributed to differences in prevalent abstinence. There was no difference between the groups in prevalent abstinence at 12 months postpartum. CONCLUSIONS: Relapse prevention interventions may need to be increased in duration and potency to prevent post-partum relapse.

Partner smoking status and pregnant smoker's perceptions of support for and likelihood of smoking cessation.

Perceptions of support for cessation of smoking during pregnancy, likelihood of quitting, and partner smoking status were explored in a sample of 688 pregnant smokers (372 baseline smokers and 316 baseline quitters). Women with nonsmoking partners were significantly more likely to be baseline quitters than women with partners who smoked. Baseline quitters reported significantly more positive support from their partners than did continuing smokers (p = .02). Neither partner smoking status nor partner support at baseline was associated with cessation or relapse later in pregnancy. Women reported greater support, both positive and negative, from nonsmoking partners than from partners who smoked (p = .001). Among partner smokers, those who were trying to quit were perceived to be particularly supportive. Cessation interventions for expectant fathers may increase pregnant women's success at quitting.

Differences in preconceptional and prenatal behaviors in women with intended and unintended pregnancies.

OBJECTIVES: This study examined whether pregnancy intention was associated with cigarette smoking, alcohol drinking, use of vitamins, and consumption of caffeinated drinks prior to pregnancy and in early pregnancy. METHODS: Data from a telephone survey of 7174 pregnant women were analyzed. RESULTS: In comparison with women whose pregnancies were intended, women with unintended pregnancies were more likely to report cigarette smoking and less likely to report daily vitamin use. Women with unintended pregnancies were also less likely to decrease consumption of caffeinated beverages or increase daily vitamin use. CONCLUSIONS: Pregnancy intention was associated with health behaviors, prior to pregnancy and in early pregnancy, that may influence pregnancy course and birth outcomes.

Prevention of pediatric drowning and near-drowning: a survey of members of the American Academy of Pediatrics.

OBJECTIVE: To assess pediatricians' knowledge about the epidemiology of childhood drowning, their opinions and current practices regarding its prevention, and their interest in taking on more responsibility for its prevention. DESIGN: A self-administered questionnaire was mailed to 800 pediatricians in the United States, randomly selected from the American Academy of Pediatrics' approximately 18,000 full fellows. RESULTS: A total of 560 completed surveys were returned, a response rate of 70.1%. Although 85% of respondents believe it is the responsibility of pediatricians to become involved in community and/or legislative efforts to prevent childhood drowning, only 4.1% were involved in such efforts. Only a minority of respondents provided written materials and anticipatory guidance on drowning prevention to their patients. Women were more likely than men to discuss drowning prevention with their patients. Younger physicians were more likely than older physicians to discuss drowning prevention with their patients. Physicians who received formal education on drowning prevention during their pediatric residency training were more likely to provide written materials and anticipatory guidance on drowning prevention to their patients. However, only 17.9% of respondents received formal education on drowning prevention during their pediatric residency training. Seventy-four percent of all respondents felt that further education on the prevention of childhood drowning and near-drowning would be useful to them. CONCLUSION: Although drowning is the second leading cause of death by unintentional injury in the pediatric population (aged 0 to 19 years), most pediatricians do not routinely provide information to their patients, or to their patients' parents, on drowning prevention. IMPLICATION: Pediatricians have been effective child advocates in many areas of injury prevention. If the prevention of drowning is made a priority in pediatric practice, many more children's lives will be saved.

Community education for cardiovascular disease prevention. Morbidity and mortality results from the Minnesota Heart Health Program.

The Minnesota Heart Health Program was a community trial of cardiovascular disease prevention methods that was conducted from 1980 to 1990 in three Upper Midwestern communities with three matched comparison communities. A 5- to 6-year intervention program used community-wide and individual health education in an attempt to decrease population risk. A major hypothesis was that the incidence of validated fatal and nonfatal coronary heart disease and stroke in 30- to 74-year-old men and women would decline differentially in the education communities after the health promotion program was introduced. This hypothesis was investigated using mixed-model regression. The intervention effect was modeled as a series of annual departures from a linear secular trend after a 2-year lag from the start of the intervention program. In the education communities, 2,394 cases of coronary heart disease and 818 cases of stroke occurred, with 2,526 and 739 cases, respectively, being seen in the comparison communities. The overall decline in coronary heart disease incidence was 1.8 percent per year in men (p = 0.03) and 3.6 percent per year in women (p = 0.007). For stroke, there were no significant secular trends. The authors recently published findings showing minimal effects of sustained intervention on risk factor levels. In the current report, there was no evidence of a significant intervention effect on morbidity or mortality, either for coronary heart disease or for stroke.

Promoting abstinence among relapsed chronic smokers: the effect of telephone support.

OBJECTIVES: The present study used telephone support both to sustain abstinence and to encourage renewed quit attempts in smokers who had completed an intensive smoking cessation clinic. METHODS: Subjects were hard-core smokers (n = 1083) who had attended a multisession cessation clinic. They were then assigned randomly to receive telephone support (intervention calls 3, 9, and 21 months after the targeted cessation clinic quit date) or no further intervention. RESULTS: In the intervention condition, subjects who relapsed were significantly more likely to resume abstinence (that is, to recycle) than those in the comparison condition at follow-up (6 months: 17.8% vs 11.3%; 24 months: 25.7% vs 18.2%). Telephone support was not effective in preventing relapse, and overall differences in abstinence outcome were not significant. CONCLUSIONS: The major hypothesis of the current study--that telephone support would enhance the resumption of abstinence--received partial support. However, there was no evidence either of an overall treatment effect or of an effect in preventing relapse. Telephone outreach may be more effective in the context of self-help or other less intensive interventions.

Determinants of compliance with a national smoke-free hospital standard.

OBJECTIVE: To determine the extent of compliance with the new Joint Commission on Accreditation of Healthcare Organizations (JCAHO) standard requiring acute care hospitals to be smoke-free, and to identify predictors of adoption of smoke-free hospital policies. DESIGN: We conducted a survey of a national sample of acute care hospitals and developed a predictive model for implementation of smoke-free policies during multiple logistic regression. We examined numerous factors that might predict adoption of smoke-free policies, such as hospital characteristics, patient care services, and experience with smoke-free initiatives. SETTING AND PARTICIPANTS: A systematic 20% sample of JCAHO-accredited hospitals in the United States (n = 1278). Military, Department of Veterans Affairs, Indian Health Service, psychiatric, substance abuse treatment, and children's hospitals were excluded. MAIN OUTCOME MEASURE: Compliance with the JCAHO standard. RESULTS: The response rate was 85%. Six-five percent of hospitals were in compliance with the standard 16 months after it was introduced. Factors that were independently and positively associated with implementation of smoke-free policies were administrative support (odds ratio [OR], 7.82; 95% confidence interval [Cl], 2.05 to 29.65) and inpatient smoking cessation services (OR, 1.24; 95% Cl, 1.02 to 1.52). Factors negatively associated with implementation of smoke-free policy were the number of psychiatric treatment beds (OR, 0.57; 95% Cl, 0.14 to 0.81), number of substance abuse treatment beds (OR, 0.17; 95% Cl, 0.11 to 0.26), and presence of an active task force to address smoking policy (OR, 0.56; 95% Cl, 0.40 to 0.77). CONCLUSIONS: The majority of acute care hospitals are in compliance with the JCAHO national smoke-free policy initiative. The standard is well accepted by most patients and employees. It is critical to address the challenges presented by special populations, such as psychiatry patients, to accomplish the goal of completely smoke-free hospitals.

Reported treatment of hypertension by family physicians in Sweden and Minnesota: a physician survey of practice habits.

OBJECTIVES: To compare family physicians' reported practice habits on hypertension in Sweden and Minnesota, and to assess to what extent different national guidelines account for differences. DESIGN: Random samples of family physicians were selected for telephone interviews on their practice of hypertension. SETTING: Primary care in southern Sweden and in Minnesota. SUBJECTS: Family medicine specialists. Participation rates were 236/264 (89%) in Sweden and 183/209 (88%) in Minnesota. MAIN OUTCOME MEASURES: Cut-off levels, and non-pharmacological and pharmacological treatment of hypertension, related to three case scenarios: a 48-year-old man, a 65-year-old man and a 65-year-old woman. RESULTS: Swedish physicians reported significantly higher levels of diastolic blood pressure than Minnesota physicians for the institution of treatment of hypertension for all case scenarios. In both countries, physicians adhered to the cut-off levels of their national guidelines in the case of the 48-year-old man. Minnesota physicians did not use age as a modifying factor for treatment cut-off levels, as did Swedish physicians. Swedish physicians emphasized alcohol, fat and stress reduction, and Minnesota physicians weight and salt reduction as non-pharmacological treatment. While Swedish physicians generally preferred beta-blockers, Minnesota physicians chose ACE inhibitors or calcium channel blockers as the first choice drug. CONCLUSION: Swedish and US guidelines on hypertension were identical except for higher cut-off level for drug treatment in Sweden. Minnesota physicians reported cut-off levels close to national guidelines. For 65-year-old patients, Swedish physicians reported applying a higher cut-off level than indicated by guidelines. Swedish physicians also reported preferring less expensive drugs. As a consequence of the differing national guidelines and the identified physicians' practice habits in the two medical communities, it is likely that the segments of the populations treated and the drug costs differ substantially.

Adolescent parity and infant mortality, Minnesota, 1980 through 1988.

The association of parity and infant mortality was studied using linked birth-death files for 46,985 infants born to 11- to 19-year-old Minnesota residents between 1980 and 1988. Compared with infants of primiparas, infants of multiparas were at twice the risk for infant and postneonatal death but at no increased risk for neonatal death. They were also at two to three times the risk for deaths due to accidents, infections, and sudden infant death syndrome. The higher sociodemographic disadvantage and poorer prenatal care of multiparas did not explain the excess infant mortality risk that was concentrated in causes of death that are potentially preventable through primary care and parent education.

Changes in adult cigarette smoking in the Minnesota Heart Health Program.

OBJECTIVES: The Minnesota Heart Health Program was a research and demonstration project designed to reduce risk factors for heart disease in whole communities. This paper describes smoking-specific interventions and outcomes. METHODS: Three pairs of matched communities were included in the study. After baseline surveys, one community in each pair received a 5-year education program, while both cross-sectional and cohort surveys continued in all sites. Adult education programs for smoking cessation included Quit and Win contests, classes, self-help materials, telephone support, and home correspondence programs. RESULTS: Encouraging short-term results were obtained for several adult education programs. Overall long-term outcomes were mixed, with evidence of an intervention effect only for women in cross-sectional survey data. Unexpectedly strong secular declines in smoking prevalence were observed in comparison communities. CONCLUSIONS: The findings suggest that community education may be unlikely to exceed dramatic secular reductions in smoking prevalence. The success of several key interventions and the incorporation of Minnesota Heart Health Program interventions by education communities are encouraging, however.

Program evaluation strategies for community-based health promotion programs: perspectives from the cardiovascular disease community research and demonstration studies.

Community-based programs are being widely adopted in the struggle to prevent chronic disease. Program evaluation of community-based programs involves a particular set of problems stemming from the variety of activities being undertaken simultaneously, the multiple intermediate goals of the programs and the rapidity with which the programs evolve. An analysis of the experience of four large community-based cardiovascular disease research and demonstration studies (Stanford Five-City Project, Minnesota Heart Health Program, Pawtucket Heart Health Program and the German Cardiovascular Prevention Project) provides valuable models, methodologies and strategies for planning and conducting evaluations of public health programs or community studies. By comparing and combining their experiences, the four programs have identified eight categories of evaluation for community studies, including formative evaluation, quality assurance, assessment of delivered dose, assessment of received dose, component program impact, intermediate outcomes, community impact and cost analysis. This paper presents information on the strategies by which each of the four programs addressed these evaluation categories.

Mass media and school interventions for cigarette smoking prevention: effects 2 years after completion.

The long-term cigarette smoking prevention effects of mass media and school interventions were assessed. Adolescents in two communities received both mass media and school interventions; those in two matching communities received only school interventions. Surveys of 5458 students were conducted at baseline in grades 4 through 6 and 2 years after the 4-year interventions were completed, when students were in grades 10 through 12. Students exposed to the media-plus-school interventions were found to be at lower risk for weekly smoking (odds ratio = 0.62, 95% confidence interval = 0.49, 0.78) than those receiving school interventions only, indicating that the effects of the combined interventions persisted 2 years after the interventions' completion.
