Using a population-based cancer registry for recruitment of newly diagnosed patients with ovarian cancer.

BACKGROUND: Although rarely used for clinical trial recruitment in the United States, population-based registries are a potential resource for identification of patients with cancer for some kinds of research trials. They record fairly detailed information on a cancer patient's condition at the time of diagnosis (stage, histologic types, and other clinical and demographic variables) and record all patients in a geographic area. This information can be used to identify patients eligible for intervention trials. METHODS: Using a cancer registry to identify newly diagnosed patients and their physicians, this study recruited 60 women for a feasibility trial of a psychosocial intervention designed to improve the quality of life for women with ovarian cancer. Active consent from physicians was obtained before contacting patients. RESULTS: Of 441 women identified as potentially eligible from the cancer registry, 364 (82%) were screened for eligibility and 179 (41%) were eventually determined to be eligible. Of the identified eligible women, 60 (34%) were recruited and enrolled in the trial. CONCLUSIONS: This rate of recruitment is within the range of recruitment rates reported in past studies examining efforts to enroll patients in clinical trials at single institutions. These findings suggest that registry-based recruitment efforts may be useful for expanding recruitment to the larger community.

Does parental smoking cessation encourage their young adult children to quit smoking? A prospective study.

AIMS: To investigate the extent to which parental early and late smoking cessation predicts their young adult children's smoking cessation. DESIGN: Parental early smoking cessation status was assessed when children were in 3rd grade, parental late smoking cessation was assessed when children were in 11th grade, and young adult children's smoking cessation was assessed 2 years after high school. SETTING: Forty Washington State school districts participated in the Hutchinson Smoking Prevention Project. PARTICIPANTS AND MEASUREMENTS: Participants were the 1553 families in which parents were ever regular smokers who had a young adult child smoking at least weekly at 12th grade who also reported their smoking status 2 years later. Questionnaire data were gathered on parents and their young adult children (49% female and 91% Caucasian) in a cohort with a 94% retention rate. FINDINGS: Parents who quit early had children with 1.8 (OR = 1.80; 95% CI = 1.22, 2.64) times higher odds of quitting smoking for at least 1 month in young adulthood compared to those whose parents did not quit early. In contrast, there was no association (OR = 0.84; 95% CI = 0.47, 1.51) between parents quitting late and their young adult children's smoking cessation. CONCLUSIONS: Parental early smoking cessation is associated with increased odds of their young adult children's smoking cessation. Parents who smoke should be encouraged to quit when their children are young.

Examining the cost-effectiveness of cancer screening promotion.

Cost-effectiveness analyses (CEAs) can help to quantify the contribution of the promotion of a screening program to increased participation in screening. The cost-effectiveness (C/E) of screening promotion depends in large part on the endpoints of interest. At the most fundamental level, the C/E of a strategy for promoting screening would focus on the attendance rate, or cost per person screened, and the C/E would be influenced by the costs of promotion, as well as by the size and responsiveness of the target population. In addition, the costs of screening promotion (measured as the cost per additional participant in screening) can be included in a CEA estimate of the screening technology. In this case, depending on the efficacy of the screening test and the costs and influence of the promotion, the C/E of screening may improve or become poorer. In the current study, the authors reviewed the literature on the C/E of cancer screening promotion. The following lessons were learned regarding the C/E of screening and its promotion: 1) high-quality information on the C/E of screening is increasingly available; 2) cost-effective promotion of screening is dependent on cost-effective screening strategies; 3) quality-of-life effects may be important in assessing the overall C/E of screening programs; 4) research efforts aimed at identifying cost-effective approaches to screening promotion are useful but sparse; 5) C/E studies should be better incorporated into well designed effectiveness research efforts; 6) variations in C/E according to intervention characteristics, population characteristics, and context should be evaluated in greater depth; 7) the long-term effects of screening promotion are critical to assessing C/E; 8) the effects of promotion on costs of screening must be better understood; and 9) CEA must be interpreted in light of other information. The authors showed that CEA can be a valuable tool for understanding the merits of health promotion interventions and that CEA is particularly valuable in identifying screening strategies that might be promoted most cost-effectively.

Worry about ovarian cancer risk and use of screening by high-risk women: how you recruit affects what you find.

Several studies have described the characteristics of women at high-risk for ovarian cancer who are participating in registry studies and high-risk screening programs. These studies have found high-risk women to report high levels of perceived risk and worry about their risk for ovarian cancer. In contrast, population based studies have found that while high-risk women did report high levels of perceived risk, they did not report high levels of worry about their risk. In this study, we examine reports of perceived risk, worry about ovarian cancer, and use of screening by high-risk women recruited to participate in a survey from several recruitment sources. These sources include self-, physician-, and affected patient relative-referral, a fundraising mailer, and a mass mailing to a commercial mailing list. High-risk women recruited via mass mailing were less likely than those recruited via physicians or affected relatives to report either worry about their risk or use of ovarian cancer screening tests.

Antismoking parenting practices are associated with reduced rates of adolescent smoking.

BACKGROUND: Although parental smoking is clearly one important influence on children's smoking, it is still unclear what are the many mechanisms by which parents influence their children's smoking. Antismoking actions are one potential mechanism. OBJECTIVE: To determine whether parental antismoking actions including having rules about smoking in one's home, using nonsmoking sections of public establishments, or asking others not to smoke in one's presence are associated with adolescents' adoption of smoking. DESIGN: A cross-sectional survey. SETTING: Rural and suburban communities in western Washington State. PARTICIPANTS: Population-based cohort of 3555 adolescents and their parents. MAIN OUTCOME MEASURE: Daily smoking in 12th grade. RESULTS: Adolescents of parents who report having rules about smoking in one's home, using nonsmoking sections of public establishments, or asking others not to smoke in one's presence were significantly less likely to smoke than adolescents of parents who did not engage in antismoking actions. This association of antismoking action and reduced smoking was found for children of both smoking and nonsmoking parents. CONCLUSION: Parents' antismoking actions may help prevent smoking by their teenaged children.

The relationship between perceived risk, affect, and health behaviors.

In this study, we examined the relationship between affect and health behaviors. The study participants were women (n = 1366), aged 18-74 years, who had not been previously diagnosed with breast cancer, who had a working telephone number and address, who spoke English, who planned to be in their present residence for at least 1 year, and who were willing to complete the survey requirements. General anxiety was a significant predictor of eating a low-fat diet, in a quadratic manner (p < .05). General anxiety and breast cancer worry were significant predictors of breast self-examination, in a quadratic fashion (p < .05). None of four independent variables, perceived risk, cancer worry, general anxiety, and general depression scores, were significantly related to mammography use, physical activity, or fruit and vegetable consumption. We must look beyond risk perceptions and family history to understand motivations for health behaviors.

Breast cancer risk counseling improves women's functioning.

Helping people cope with health risks is an important area for research and practice. Counseling offers people the opportunity to relieve their distress and improve the ways in which they manage their health issues. This study was a randomized test of two different counseling methods, genetic and psychosocial counseling, compared to a control group. Eligibility requirements included being between 18 and 74 years old, having at least one relative with breast cancer, not having a family history consistent with carrying a BRCA1/2 mutation for breast cancer risk, having no personal history of breast or ovarian cancer, living within 60 miles of the research institute, and willingness to complete the research requirements of the project. Perceived risk decreased by 50% for participants in the two counseling groups relative to comparison participants. Cancer worry decreased in both counseling groups by one scale point (P < 0.05). These results indicate that counseling can relieve women's negative reactions to breast cancer risk.

Optimism, perceived risk of breast cancer, and cancer worry among a community-based sample of women.

Optimism is frequently inversely associated with distress; however, less is known about the mechanisms underlying this relationship. Optimism can be defined as having a generalized positive expectancy about the future. The authors hypothesized that a specific expectancy might mediate the relationship between optimism and distress. That model was tested using perceived risk of breast cancer as a specific measure of expectancy and cancer worry as a measure of distress in a community-based sample of 1,366 women. It was hypothesized that optimism would be inversely associated with cancer worry and that perceived risk of breast cancer would mediate the relationship between optimism and cancer worry. Multiple regression analyses revealed that perceived risk partially mediated the relationship between optimism and cancer worry.

Assertiveness with physicians: does it predict mammography use?.

In a prior study we found that women's self-reported assertiveness with their healthcare providers was associated with their use of mammography in a population-based cross-sectional sample of women. Women who reported being more assertive, by repeating information if they felt their doctor didn't hear them, asking their doctor to explain information they didn't understand, or reminding their doctor about screening tests, were more likely to have received a mammogram recently than those who reported being less assertive. Here we examined how women's self-reports of assertiveness predicted their use of mammography three years later. We examined this using a population-based sample of 781 women living in rural Washington State who were participating in a trial of mammography promotion. We found that assertive women were younger on average than less assertive women, but that even after controlling for age, education, income, and marital status, women who reported being assertive with their doctor in 1994 were more likely to receive regular mammograms in the next three years than those who did not (OR 2.1; CI 1.5, 2.9). If future studies also suggest that assertiveness predicts use of mammography or other preventive healthcare services, it would be valuable to examine the promotion of assertiveness as a means of improving public health.

Compliance of average- and intermediate-risk women to semiannual ovarian cancer screening.

OBJECTIVE: To report rates of compliance with an ovarian cancer screening protocol using serum CA125 and transvaginal sonography (TVS), performed semiannually on an alternating schedule, among participants at average or intermediate risk for developing ovarian cancer. METHODS: Two hundred ninety-two women at average or intermediate risk for developing ovarian cancer were randomly assigned to arms of a controlled clinical trial in which they received ovarian cancer screening consisting of serum CA125 alternating with TVS performed semiannually over 18 months, either alone or in combination with ovarian cancer risk education. A computerized tracking system generated screening appointment reminder letters and monitored adherence to scheduled screening. Participants overdue for scheduled screens received follow-up telephone calls consisting of up to four reminder messages left at 1-week intervals, and one to two interim attempts to reach participants between messages. The compliance rate for each screen was calculated as a ratio of the number of participants successfully completing the screen relative to the number expected to attend. Compliance rate by screen was: screen 1 (CA125) (97.3%), screen 2 (TVS) (82.5%), screen 3 (CA125) (79.0%), and screen 4 (TVS) (64.5%). One hundred seventy-two women completed all four screens and were classified as adherent to the screening protocol. Analysis by screening modality suggests that participants were more compliant to screens involving CA125. Age, educational background, distance from screening center, personal or family history of cancer, perceived risk of ovarian cancer, pre-enrollment ovarian cancer screening behavior, receiving an abnormal screen test result, and participation in ovarian cancer risk education sessions were not associated with adherence to the screening protocol or compliance to any of the screens. CONCLUSIONS: Despite extensive follow-up, compliance of average- and intermediate-risk women to an ovarian cancer screening protocol requiring semiannual screening diminishes rapidly. We propose that a semiannual ovarian cancer screening protocol, particularly one including TVS, may be too intensive for use in this population.

Nine-year prospective association between older siblings' smoking and children's daily smoking.

PURPOSE: To explore the hypothesis that older siblings' smoking, after controlling for parents' smoking, influences children's smoking. METHODS: Study participants were 2981 students in the control cohort of a school-based smoking prevention randomized trial for whom parents' smoking and older siblings' smoking data were collected at 3rd grade and daily smoking data was assessed 9 years later through a self-report questionnaire at the 12th grade. Data were analyzed using conditional logistic regression and likelihood ratio tests. RESULTS: For families in which no parent smoked, the 12th grade prevalence of daily smoking was 31% when at least one older sibling smoked compared to 18% when no older sibling smoked. For families in which at least one parent smoked, the 12th grade prevalence of daily smoking was 41% when at least one older sibling smoked compared to 29% when no older sibling smoked. There was a substantial increase in the odds (OR = 1.60, p =.004) of children's daily smoking at 12th grade when their older siblings smoked, even after adjusting for parents' smoking. CONCLUSIONS: Older siblings' smoking is associated with increased risk of children's smoking after adjusting for parents smoking. Furthermore, there was no evidence to suggest that the influence of older siblings' smoking was different in families where no parent smoked compared to those where at least one parent smoked. Also, there was no evidence that the influence of older siblings' smoking was different in boys vs. girls.

Nine-year prospective relationship between parental smoking cessation and children's daily smoking.

AIMS: The first prospective investigation of the extent to which parental smoking cessation predicts their children's daily smoking. DESIGN: Parental smoking status was assessed when children were aged 8/9 years and children's smoking status was assessed at age 17/18 years. SETTING: Twenty Washington State school districts in the control group of the Hutchinson Smoking Prevention Project. PARTICIPANTS AND MEASUREMENTS: Questionnaire data were gathered on 3012 children (49% female and 91% Caucasian) and both of their parents in a cohort with a 95% retention rate. FINDINGS: When both parents quit smoking, children's odds of daily smoking were reduced by 39% (95% CI = 15%,56%) compared to when both parents were current smokers.Furthermore, when both parents never smoked then children's odds of daily smoking were reduced by 71% (95% CI = 62%,78%). CONCLUSIONS: Parental smoking cessation is associated with reduced risk of their children's daily smoking. Parents who quit still place children at substantially higher risk compared to parents who never smoked.

Awareness and concern about ovarian cancer among women at risk because of a family history of breast or ovarian cancer.

Research on women at risk for breast cancer because of family history suggests that a substantial proportion need education and counseling to assist them in their efforts to understand their risk of breast cancer and that some do not get appropriate breast cancer screening. Although women at high genetic risk for breast cancer are at elevated risk for ovarian cancer as well, few studies have examined these women's needs for education and counseling about ovarian cancer risk. This study examined awareness of ovarian cancer, perceived risk of breast and ovarian cancer, interest in genetic testing, and use of screening for breast and ovarian cancer in a population-based sample of women at high risk for breast and ovarian cancer because of a strong family history of cancer at one or both sites. We found that most high-risk women are not getting the information and care they need with respect to their risk for ovarian cancer. Almost 75% have not heard much about their risk for ovarian cancer. More than 90% failed to use 1 or another of 2 possible tests used for ovarian cancer screening regularly.

Breast cancer worry and mammography use by women with and without a family history in a population-based sample.

Worry about breast cancer risk has been found to be a barrier to mammography use by women with a family history of breast cancer in some studies, although worry is generally found to increase mammography use among average risk women. Our study sought to examine the association of worry with mammography use in a population-based sample of women stratified by family history associated risk for breast cancer. A population-based sample of 6512 women completed a telephone interview. Fourteen percent (n = 948) of these reported a family history suggestive of elevated risk, including at least one affected first-degree relative. To examine the effects of worry on mammography use in women, a logistic regression model, including family history associated risk, age, and worry, was tested. Although family history was a significant predictor of mammography use in bivariate examinations, in the multivariate model it was not significant after adjustment for age and worry, which remained statistically significant predictors of mammography (P < 0.05). The association between worry and mammography use was best described by a quadratic term. Interaction terms for family history-associated risk and worry were not statistically significant predictors of mammography use. Worry about breast cancer risk appears to be associated with mammography use in an inverted u-shaped pattern. Women reporting moderate levels of worry were more likely to use mammography annually than those who were either mildly or severely worried. Severe worry may be a barrier to mammography use for all women not only those with a family history.

Effectiveness of telephone counseling for mammography: results from five randomized trials.

BACKGROUND: Women over age 50 continue to be underscreened for breast cancer. The purpose of this report is to compare the effectiveness of a barrier-specific telephone counseling intervention across the five study sites of the Breast Cancer Screening Consortium (BCSC). METHODS: Each of the BCSC projects was a randomized study of the effectiveness of telephone counseling (TC) in comparison to a control condition. Eligible underusers were identified and surveyed by telephone before and after the implementation of the interventions. Data from a total of 3,461 underusers were analyzed. We tested whether significantly more women randomized to TC than to control were regular mammography users at the follow-up survey. Data were analyzed separately by site. RESULTS: Overall, TC was not significantly more effective than control in encouraging regular mammography. The pooled consortium-wide odds ratio was 1.08 (95% confidence interval: 0.91 to 1.27). CONCLUSIONS: TC has the potential to support maintenance of mammogram use. Modifications are needed to maximize this potential and additional methods should be used in conjunction with TC to reach women who are underusers of mammography.

Mothers' attitudes and concerns about their children smoking: do they influence kids?

BACKGROUND: The effects of mothers' attitudes and concerns about tobacco use on whether their children take up smoking are largely unknown. This study examined the predictive effects of mothers' attitudes about tobacco and concerns about their children smoking. METHODS: Self-reported data from a large number of 12th-grade students (2,736) and their mothers were used. Mothers' attitudes and concerns were assessed when their children were 3rd graders (age 8), at the start of the smoking acquisition period; their children were then followed prospectively (with attrition of only 5%) for 9 years to the end of the period (12th grade) for the assessment of smoking behavior. RESULTS: In households in which both parents are nonsmokers, strong maternal antismoking attitudes are associated with a statistically significant approximately 50% reduction (P < 0.05) in the prevalence of smoking by adolescent children. In contrast, in households in which one or both parents are current smokers, there was no reduction in adolescent smoking associated with mothers' antismoking attitudes. CONCLUSIONS: Maternal antismoking attitudes when their children are young predict adolescents' adoption of smoking at 12th grade, but only when parental behavior is consistent with these attitudes.

Costs and cost-effectiveness of a clinical intervention to increase mammography utilization in an inner city public health hospital.

BACKGROUND: Studies have demonstrated the cost-effectiveness of screening women for breast cancer; however, the cost-effectiveness of strategies to motivate women to receive breast cancer screening has been less well studied. METHODS: A total of 196 women, aged 50 to 74, who were enrolled in a public health hospital clinic, were noncompliant with mammography screening, and had at least one routine clinic appointment during the study period (15 months) were entered into a randomized, controlled trial of a motivational intervention to increase mammography rates. Costs were captured via a modified Delphi technique, accounting records, sampling of staff time logs, and an estimation of miscellaneous and overhead costs. Summary costs were calculated using Excel spread sheets. RESULTS: Overall, 49% of women who received the intervention had a mammogram within 8 weeks of an index visit compared with 22% of control women. Calculation of the cost-effectiveness of the project showed an additional cost of $151 (1996 U.S.$) for each woman receiving the intervention and $559 for each additional woman motivated to receive a mammogram. CONCLUSIONS: Cost tracking and cost-effectiveness analysis can be done when intervening in a clinical setting, thereby allowing clinics to make informed decisions about implementing programs to increase motivation of their patients to receive screening.
