Compliance with restrictions on sale of indoor tanning sessions to youth in Minnesota and Massachusetts.

BACKGROUND: Minnesota and Massachusetts require parental permission, for persons younger than 16 or 18 years of age, respectively, for indoor tanning. OBJECTIVES: This report examines business practices and characteristics associated with sales of indoor tanning to underage girls. METHODS: Fifteen-year-old girls tried to purchase an ultraviolet tanning session in 200 indoor tanning businesses in the Minneapolis-St Paul and Boston areas without parental consent. Business characteristics were recorded. Later, businesses were interviewed by telephone about their facilities and practices. RESULTS: Eighty-one percent of businesses sold a session to an underaged buyer on at least one of two tries. Illegal purchases did not differ by state. Businesses least likely to sell were larger, dedicated to indoor tanning, required employee certification, and had a minimum age of sale for their business. However, businesses in each of these categories still sold tanning sessions to underaged adolescents at 44% to 62% of the visits. Employees who requested parental consent or age identification almost never sold a session. LIMITATIONS: Businesses in Minnesota and Massachusetts only were included. CONCLUSION: Minnesota and Massachusetts laws specifying a minimum age of sale for indoor tanning are ineffective.

Functional limitations in elderly female cancer survivors.

BACKGROUND: The elderly population, including many who are long-term cancer survivors, is increasing. Aspects of quality of life in elderly cancer survivors are not well understood. METHODS: Subjects were women who enrolled in a population-based cohort study in 1986. At follow-up in 1997, 25,719 women, at a median age of 72 years, reported on functional limitations. We used logistic regression to calculate prevalence odds ratios (ORs) and proportional hazards regression to calculate prevalence ratios (PRs) for associations between cancer survivor status and functional limitations, adjusting for baseline (precancer) characteristics including obesity, smoking, and diabetes. RESULTS: Women who were cancer survivors for less than 2 years reported the most functional limitations, but long-term (5 or more years) cancer survivors remained more likely than cohort members who had not had cancer to report that they were unable to do heavy household work (42% of 1068 5-year survivors, versus 31% of 23 501 who never had cancer, multivariable OR = 1.47, 95% confidence interval [CI] = 1.27 to 1.69; PR = 1.22, 95% CI = 1.10 to 1.34), unable to walk a half mile (26% versus 19%, OR = 1.31, 95% CI = 1.1 to 1.54; PR = 1.16, 95% CI = 1.02 to 1.32), and unable to walk up and down stairs (9% versus 6%, OR = 1.34, 95% CI = 1.05 to 1.72; PR = 1.25, 95% CI = 1.00 to 1.56). The increased prevalence of functional limitations was apparent for 5-year survivors of breast cancer and also certain other cancers. CONCLUSIONS: Our findings support the need to target elderly cancer survivors for interventions to maintain or regain physical function.

Do adolescent indoor tanners exhibit dependency?

BACKGROUND: Indoor tanning is a common adolescent risk behavior that has been hypothesized to be motivated and maintained by the mood-altering effects of ultraviolet light. OBJECTIVE: Our purpose was to explore heretofore anecdotal reports that indoor tanning leads to dependency. METHODS: A telephone interview was conducted among 1275 adolescents, ages 14 to 17 years. Self-reported difficulty in quitting indoor tanning was assessed among 267 adolescents (20.9% of total) who tanned indoors more than once in the previous year in relation to age of initiation, frequency of use, and positive or negative consequences of the practice. RESULTS: Difficulty in quitting was more likely with younger age at initiation (age 13 years or younger vs ages 16 to 17; odds ratio = 4.3, 95% confidence interval 1.3-14.7) and higher frequency of use (P = .009), even after accounting for positive or negative consequences of indoor tanning and other demographic characteristics. LIMITATIONS: This was a cross-sectional study design with a limited outcome measure. CONCLUSION: Although preliminary, our findings for age at initiation and frequency of use in relation to difficulty in quitting indoor tanning are consistent with other potentially addictive behaviors taken up during adolescence.

Indoor tanning by adolescents: prevalence, practices and policies.

Despite known acute and chronic health effects from the use of indoor tanning, including the potential for all forms of skin cancer, the practice is popular in the United States (US) and Europe. A review of the scientific literature that examines adolescents and indoor tanning use was undertaken, summarising what is known about prevalence and practices among adolescents, characteristics associated with adolescent use, and policies that regulate adolescent access to indoor tanning facilities. The prevalence of indoor tanning is consistently found to be higher among girls than boys and to increase with age in both Europe and the US. An examination of other demographic characteristics, skin cancer risk factors, knowledge, attitudes and social factors points to higher prevalence of the behaviour among adolescents with positive attitudes towards tans and whose friends or parents also tan indoors. Adolescent access to indoor tanning is rarely regulated in the US or Europe, and where regulations exist, business compliance is low. In addition, businesses actively market their product to adolescents as they organise to limit further regulations prohibiting adolescent access. Pricing, licensure, advertising restrictions and media campaigns, in combination with adolescent-targeted interventions, are possible strategies that could be tested for their effectiveness to reduce adolescent indoor tanning use. Harm reduction policies, such as eye protection, that reduce risk for adolescents who choose to tan indoors, are also important.

Sanitarians' work with indoor-tanning businesses: findings from interviews in two major metropolitan areas.

In spite of health risks, indoor tanning is a popular practice and a growing industry. Although published studies indicate that tanning businesses' compliance with regulations is poor, no studies describe enforcement activity and the related knowledge and perceptions of environmental health professionals. As part of a larger study of indoor tanning in Minnesota and Massachusetts, both states with statutes that regulate tanning, the investigation reported in this paper involved interviews of 27 sanitarians in the Twin Cities and 30 sanitarians in the Boston metropolitan area about their awareness, experiences, and practices. Overall, Massachusetts performed better than Minnesota with respect to familiarity with regulations (93 percent versus 67 percent), routine business inspections (90 percent of agencies versus 27 percent), and priority given by agencies to indoor-tanning work-differences likely attributable to a stronger state statute. Participants in both states, however, recalled few aspects of the regulations and were able to identify few of the health risks associated with indoor tanning, and most reported receiving inadequate training. Various steps must be taken to improve environmental health work with tanning businesses, including educating the public, strengthening regulations, addressing resource issues, and training sanitarians.

Risk factors for breast cancer in elderly women.

As the population ages, an increasing fraction of women diagnosed with breast cancer will be elderly. Heterogeneity of breast cancer risk factors between pre- and postmenopausal women is recognized, but few studies have examined elderly women specifically. The authors describe the age-specific influence of risk factors for postmenopausal breast cancer, with emphasis on women aged 75 or more years. Among 36,658 members of the Iowa Women's Health Study (1986-2001), a population-based cohort study, 428 incident breast cancers were diagnosed in women aged 55-64 years, 1,297 in women aged 65-74 years, and 561 in women aged 75-84 years. Women with a body mass index (weight (kg)/height (m)(2)) in the highest versus the lowest quartile were at increased risk of breast cancer at age 75 or more years (adjusted hazard ratio = 1.44, 95% confidence interval (CI): 1.12, 1.84). Family history of breast cancer (hazard ratio = 1.54, 95% CI: 1.24, 1.93 for a first-degree family history vs. none) and an older age at menopause (p(trend) = 0.07) conferred increased risk for women aged 75 or more years, and a high number of livebirths was protective (hazard ratio = 0.67, 95% CI: 0.51, 0.88 for five or more births compared with one or two). Obesity, a modifiable risk factor, remained positively associated with breast cancer for all age groups of postmenopausal women.

Characteristics associated with use or intention to use indoor tanning among adolescents.

BACKGROUND: Indoor tanning is a popular behavior that may increase skin cancer risk. OBJECTIVE: To examine characteristics associated with use or intention to use indoor tanning among adolescents. METHODS: A telephone interview was conducted with 1273 adolescents, aged 14 to 17 years, in the Minneapolis-St Paul, Minn, and Boston, Mass, metropolitan areas. Questions included demographic and phenotypic characteristics, knowledge, attitudes, social factors, use of indoor tanning, and intention to tan indoors. RESULTS: Twelve percent of boys and 42% of girls had tanned indoors. Among nontanners, 22.4% planned to start, and 77.2% of tanners planned to continue tanning indoors. Nontanners and tanners at risk for future indoor tanning use were each significantly more likely to be female, less likely to use sun protection, less knowledgeable about skin cancer risks, more likely to agree that tans were attractive, and more strongly influenced by social factors compared with their low-risk counterparts. CONCLUSIONS: Our data suggest that intention to tan indoors may identify a group of adolescents at risk for adopting the behavior; prospective studies are needed for confirmation.

Current research promises and challenges in behavioral oncology: report from the American Society of Preventive Oncology annual meeting, 2002.

The Behavioral Oncology Interest Group of the American Society of Preventive Oncology held a Roundtable session on March 10, 2002, at the American Society of Preventive Oncology annual meeting in Bethesda, Maryland, to discuss the current state-of-the-science in behavioral approaches to cancer prevention and control and to delineate priorities for additional research. Four key areas were considered: (a) behavioral approaches to cancer genetic risk assessment and testing; (b) biological mechanisms of psychosocial effects on cancer; (c) the role of risk perceptions in cancer screening adherence; and (d) the impact of tailored and targeted interventions on cancer prevention and control research. The evidence reviewed indicates that behavioral approaches have made significant contributions to cancer prevention and control research. At the same time, there is a need to more closely link future investigations to the underlying base of behavioral science principles and paradigms that guide them. To successfully bridge the gap between the availability of effective new cancer prevention and control technologies and the participants they are meant to serve will require the development of more integrative conceptual models, the incorporation of more rigorous methodological designs, and more precise identification of the individual and group characteristics of the groups under study.

Adherence to the AICR cancer prevention recommendations and subsequent morbidity and mortality in the Iowa Women's Health Study cohort.

In 1997, the American Institute for Cancer Research (AICR) published 14 recommendations related to diet for individuals to reduce cancer incidence on a global basis; smoking was also discouraged. We operationalized these into nine recommendations that are particularly relevant to western populations in a cohort of 29,564 women ages 55 to 69 years at baseline in 1986 who had no history of cancer or heart disease. The cohort was followed through 1998 for cancer incidence (n = 4,379), cancer mortality (n = 1,434), cardiovascular disease (CVD) mortality (n = 1,124), and total mortality (n = 3,398). The median number (range) of recommendations followed was 4 (0-8), and 33% of the cohort had ever smoked. Women who followed no or one recommendation compared with six to nine recommendations were at an increased risk of cancer incidence [relative risk (RR) 1.35, 95% confidence interval (CI) 1.15-1.58] and cancer mortality (RR 1.43, 95% CI 1.11-1.85), but there was no association with CVD mortality (RR 1.06, 95% CI 0.78-1.43). We calculated the population attributable risk (PAR) to estimate the proportion of cancer incidence, cancer mortality, and CVD mortality that theoretically would have been avoidable if the entire cohort had never smoked, had followed six to nine recommendations, or had done both. The PARs for smoking were 11% (95% CI 10-13) for cancer incidence, 21% (95% CI 17-24) for cancer mortality, and 20% (95% CI 16-23) for CVD mortality. The PARs for not following six to nine recommendations were 22% (95% CI 12-30) for cancer incidence, 11% (95% CI -5 to 24) for cancer mortality, and 4% (95% CI -20 to 19) for CVD mortality. When smoking and the operationalized AICR recommendations were combined together, the PARs were 31% (95% CI 19-37) for cancer incidence, 30% (95% CI 15-40) for cancer mortality, and 22% (95% CI 4-36) for CVD mortality. These data suggest that the adherence to the AICR recommendations, independently and in conjunction with not smoking, is likely to have a substantial public health impact on reducing cancer incidence and, to a lesser degree, cancer mortality at the population level.

Association between nonsteroidal anti-inflammatory drug use and the incidence of pancreatic cancer.

Laboratory studies indicate that nonsteroidal anti-inflammatory drugs (NSAIDs) may inhibit pancreatic cancer, but epidemiologic data to support this finding are limited. We conducted a prospective study from 1992 through 1999 among 28 283 postmenopausal women who lived in Iowa to examine the association between the self-reported use of aspirin and other NSAIDs and the incidence of pancreatic cancer. Eighty incident cases of pancreatic cancer were identified during 7 years of follow-up. The multivariate-adjusted relative risk of pancreatic cancer associated with any current use of aspirin versus no use was 0.57 (95% confidence interval = 0.36 to 0.90). There was a trend of decreasing risk of pancreatic cancer incidence with increasing frequency of aspirin use per week (P(trend) =.005). Nonaspirin NSAID use was not associated with incident pancreatic cancer. These data indicate that aspirin might be chemopreventive for pancreatic cancer.

Relationship of folate, vitamin B-6, vitamin B-12, and methionine intake to incidence of colorectal cancers.

It is hypothesized that diets deficient in folate, methionine, and vitamins B-6 and B-12 cause DNA hypomethylation and, as a result, increase risk of colorectal cancers. Furthermore, it is proposed that alcohol, a methyl group antagonist, increases risk of colorectal cancers among those with low intake of folate. Data from the Iowa Women's Health Study, a population-based cohort of incident cancer, were used to examine the relationship of folate, methionine, and vitamins B-6 and B-12 to occurrence of cancers of the colon (n = 598) and rectum (n = 123) over 13 yr of follow-up. There were no independent associations of folate, methionine, or vitamins B-6 and B-12 derived from a food frequency questionnaire with incidence of colon cancer. Adjusted relative risks (RRs) of rectal cancer were similar across categories of folate, vitamin B-12, and methionine intake, but RRs increased progressively with increasing intake of vitamin B-6 [P (for trend) = 0.03]. RRs suggested that incidence of cancer of the proximal colon was lower among those with 1) high folate and high vitamin B-12 intake [RR = 0.59, 95% confidence interval (CI) = 0.39-0.89] and 2) high folate and high vitamin B-6 intake (RR = 0.65, 95% CI = 0.50-0.84) than among those with the lowest intake of these nutrients. Incidence of cancer of the proximal colon was also somewhat lower among those with high folate and low alcohol intake (RR = 0.44, 95% CI = 0.22-0.89). Findings provide limited support for an association between dietary factors involved in DNA methylation and risk of cancers of the colon and rectum.

Effectiveness of a worksite intervention to reduce an occupational exposure: the Minnesota wood dust study.

OBJECTIVES: This study assessed the effectiveness of an intervention to reduce wood dust, a carcinogen, by approximately 26% in small woodworking businesses. METHODS: We randomized 48 businesses to an intervention (written recommendations, technical assistance, and worker training) or comparison (written recommendations alone) condition. Changes from baseline in dust concentration, dust control methods, and worker behavior were compared between the groups 1 year later. RESULTS: At follow-up, workers in intervention relative to comparison businesses reported greater awareness, increases in stage of readiness, and behavioral changes consistent with dust control. The median dust concentration change in the intervention group from baseline to follow-up was 10.4% (95% confidence interval = -28.8%, 12.7%) lower than the change in comparison businesses. CONCLUSIONS: We attribute the smaller-than-expected reduction in wood dust to the challenge of conducting rigorous intervention effectiveness research in occupational settings.

Association of aspirin and nonsteroidal anti-inflammatory drug use with breast cancer.

OBJECTIVE: Previous epidemiological studies have suggested that use of aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) may be associated with reduced risk of breast cancer, but some studies have been limited in their ability to separate the effects of aspirin from other NSAIDs or to account for breast cancer risk factors. METHODS: We examined the incidence of breast cancer in association with self-reported aspirin, as well as other nonaspirin NSAID use in a large prospective cohort of postmenopausal women (n = 27,616). Over 6 years of follow-up, 938 incident breast cancers were identified. RESULTS: After adjustment for other breast cancer risk factors, any current use of aspirin or other NSAIDs compared with no use was associated with a reduction in risk of breast cancer [relative risk (RR) = 0.80, 95% confidence interval (CI) 0.67-0.95]. There was a trend of decreasing risk of incident breast cancer with increasing frequency of aspirin use (P(trend) = 0.0011). The multivariate-adjusted RR of breast cancer was 0.71 (95% CI 0.58-0.87) for women who reported using aspirin six or more times per week compared with women who reported no use. These results did not depend on whether women had early or late stage breast cancer. No association was found between nonaspirin NSAID use and incident breast cancer. The adjusted RR of using other NSAIDs six or more times per week compared with no use was 1.01 (95% CI 0.83-1.25). CONCLUSION: This prospective study corroborates other reports that use of aspirin might reduce risk of breast cancer.
