Dietary supplement use in adult cancer survivors.

PURPOSE/OBJECTIVES: To assess dietary supplement use and its association with demographic and health-related characteristics among cancer survivors and to investigate differences in supplement use patterns by cancer site. DESIGN: A cross-sectional survey. SETTING: Computer-assisted telephone survey. SAMPLE: 1,233 adult (ages 30-69) survivors participating in the Penn State Cancer Survivor Study who underwent an interviewer-administered questionnaire. METHODS: Descriptive statistics with multivariate logistic regression to determine demographic, disease, and health-related predictors of supplement use. MAIN RESEARCH VARIABLES: Use of dietary supplements and types of supplements taken. FINDINGS: Supplement use ranged from 50% among blood cancer survivors to 85% among melanoma skin cancer survivors, with an overall prevalence rate of 73%. Multivariate logistic regression revealed statistically significant associations (p values < 0.05) between supplement use and older age (>or= age 50), higher levels of education and physical activity, female gender, lower body mass index, and white ethnicity. CONCLUSIONS: Overall, a wide variety of supplements were reported, although multivitamins, calcium and vitamin D combinations, and antioxidant vitamin combinations were the most prevalent. Seventy-eight percent of supplement users took more than one supplement. IMPLICATIONS FOR NURSING: The findings support continued efforts by oncology nurses to identify the types of supplements cancer survivors are using. Nurses should caution against the use of individual supplements as well as combinations of different supplements containing nutrient quantities above recommended daily intake levels. Furthermore, oncology nurses and other healthcare professionals should be receptive to questions and prepared to initiate conversations with patients about their use of dietary supplements.

Long-term effects of cancer survivorship on the employment of older workers.

OBJECTIVE: To estimate the long-term effects of cancer survivorship on the employment of older workers. DATA SOURCES: Primary data for 504 subjects who were 55-65 in 2002 and were working when diagnosed with cancer in 1997-1999, and secondary data for a comparison group of 3,903 similarly aged workers in the Health and Retirement Study (HRS) in 2002. STUDY DESIGN: Three employment outcomes (working, working full time, usual hours per week) were compared between the two groups. Both Probit/Tobit regressions and propensity score matching were used to adjust for potentially confounding differences between groups. Sociodemographic characteristics, baseline employment characteristics, and the presence of other health conditions were included as covariates. DATA COLLECTION METHODS: Four telephone interviews were conducted annually with cancer survivors identified from tumor registries at four large hospitals in Pennsylvania and Maryland. Many of the questions were taken from the HRS to facilitate comparisons. PRINCIPAL FINDINGS: Cancer survivors of both genders worked an average of 3-5 hours less per week than HRS controls. For females, we found significant effects of survivorship on the probability of working, the probability of working full-time, and hours. For males, survivorship affected the probability of full-time employment and hours without significantly reducing the probability of working. For both genders, these effects were primarily attributable to new cancers. There were no significant effects on the employment of cancer-free survivors. CONCLUSIONS: Survivors with recurrences or second primary tumors may particularly benefit from employment support services and workplace accommodation. Reassuringly, any long-term effects on the employment of cancer-free survivors are fairly small.

Work disability associated with cancer survivorship and other chronic conditions.

The long-term effects of cancer and its treatment on employment and productivity are a major concern for the 40% of cancer survivors in the U.S. who are working age. This study's objectives were (1) to quantify the increase in work disability attributable to cancer in a cohort of adult survivors who were an average of 46 months post-diagnosis and (2) to compare disability rates in cancer survivors to individuals with other chronic conditions. Data from the Penn State Cancer Survivor Study (PSCSS) and the Health and Retirement Study (HRS) were compared. The PSCSS sample included 647 survivors age 55-65, diagnosed at four medical centers in Pennsylvania and Maryland. There were 5988 similarly aged subjects without cancer in the HRS. Adjusted odds ratios for work disability were estimated for cancer survivorship, heart disease, stroke, diabetes, lung disease, and arthritis/rheumatism with multivariate logistic regression. Even for cancer-free survivors, the adjusted disability rate was significantly higher in comparison to adults with no chronic conditions (female OR = 1.94; male OR = 1.89). There were few significant differences between disability rates for cancer and other conditions. The elevated disability rate is another argument for viewing cancer survivorship as a chronic condition potentially requiring a broad range of psychosocial services.

Employment pathways in a large cohort of adult cancer survivors.

BACKGROUND: Employment and work-related disability were investigated in a cohort of adult cancer survivors who were working when they were diagnosed from 1997 to 1999 with a variety of cancers. Employment from the time of diagnosis through the early years of survivorship was studied, self-reported effects of cancer survival on disability and employment were quantified, and risk factors associated with cancer-related disability and withdrawal from employment were identified. METHODS: One thousand four hundred thirty-three cancer survivors were interviewed by telephone from 1 year to nearly 5 years after diagnosis. They were asked retrospectively about employment from the time of diagnosis to follow-up and about work-related disability at follow-up. They also were asked whether disabilities or reasons for quitting work were cancer-related. Return to work and quitting work were projected over time in a life-table analysis. Risk factors were identified from logit analyses. RESULTS: One of five survivors reported cancer-related disabilities at follow-up. Half of those with disabilities were working. A projected 13% of all survivors had quit working for cancer-related reasons within 4 years of diagnosis. More than half of survivors quit working after the first year, when three-quarters of those who stopped for treatment returned to work. Survivors of central nervous system, head and neck, and Stage IV blood and lymph malignancies had the highest adjusted risk of disability or quitting work. CONCLUSIONS: Cancer survival sometimes has long-term effects on employment and the ability to work. Employment outcomes can be improved with innovations in treatment and with clinical and supportive services aimed at better management of symptoms, rehabilitation, and accommodation of disabilities.

Predicting the suicide attempts of lesbian, gay, and bisexual youth.

In this study predictors of serious suicide attempts among lesbian, gay, and bisexual (LGB) youth were examined. Three groups were compared: youth who reported no attempts, youth who reported attempts unrelated to their sexual orientation, and youth whose attempts were considered related to their sexual orientation. About one third of respondents reported at least one suicide attempt; however, only half of the attempts were judged serious based on potential lethality. About half of all attempts were related to youths' sexual orientation. Factors that differentiated youth reporting suicide attempts and those not reporting attempts were greater childhood parental psychological abuse and more childhood gender-atypical behavior. Gay-related suicide attempts were associated with identifiability as LGB, especially by parents. Early openness about sexual orientation, being considered gender atypical in childhood by parents, and parental efforts to discourage gender atypical behavior were associated with gay-related suicide attempts, especially for males. Assessment of past parental psychological abuse, parental reactions to childhood gender atypical behavior, youths' openness about sexual orientation with family members, and lifetime gay-related verbal abuse can assist in the prediction of suicide attempts in this population.
