Prediction of health behaviors in pediatric cancer survivors

Patterns of physical activity and sedentary behavior in child and adolescent cancer survivors assessed using wrist accelerometry: A cluster analysis approach

Physical activity levels among childhood cancer survivors are typically quantified as a total amount using time spent in various intensities. Yet, most analyses do not consider the transitory nature of children's behaviors and a more detailed approach could provide complimentary information. We aimed to explore various behavior profiles of survivors' daily and hourly physical activity patterns. We measured 8-18-year-old survivors' activity levels over 7 days using wrist accelerometry and cluster analysis. Of the 37 participant datasets, survivors engaged in mean (SD) 36.3 (19.0) min/day of MVPA and 4.1 (1.9) hrs/day of sedentary activity. The cluster analysis revealed five daily movement patterns: 'most active' (prevalence 11%), 'active' (22%), 'moderately active + moderately sedentary' (35%), 'moderately active + high sedentary' (5%) and 'least active' (27%). Younger survivors and those with less time since treatment completion were more likely to be in the active clusters. Hourly behaviors were characterized by short bursts of MVPA and moderate bouts of sedentary activity. Our approach provides an insightful analysis into the nature and timing of childhood cancer survivors' movement behaviours. Our findings may assist in the development of targeted interventions to improve physical activity levels.

Self-reported physical activity behaviors of childhood cancer survivors: comparison to a general adolescent population in Korea

PURPOSE

Adequate physical activity (PA) can significantly contribute to the prevention of undesirable health outcomes in childhood cancer survivors (CCS). This study aimed to identify the patterns of PA and related factors in Korean CCS.

METHODS

Study subjects were 184 adolescents selected from an ongoing cohort study of Korean CCS and 1,840 sex- and school grade-matched controls randomly selected from the participants of the 2019 Korea Youth Risk Behavior Web-based Survey. Information on PA and sedentary behaviors was collected by self-administered questionnaire. We estimated body mass index (BMI)-adjusted odds ratio (OR) and 95% confidence interval (CI) for the advisable healthy behaviors of CCS compared with healthy controls using conditional logistic regression analysis. In addition, the associations of advisable healthy behaviors of CCS with sociodemographic and clinical factors were estimated using multiple logistic regression analysis.

RESULTS

CCS were less likely to be physically active than controls, but this finding was evident only in males. The ORs (95% CIs) for regular exercise, moderate intensity PA, vigorous intensity PA, and walking were 0.42 (0.27-0.65), 0.39 (0.24-0.63), 0.53 (0.33-0.84), and 0.64 (0.42-0.98), respectively, in male CCS compared with same-sex controls. Compared with same-sex controls, male CCS were 4.60 times and female survivors were 15.19 times more likely to sleep longer than 8 h a day. Among CCS, males were 2.92 times and 3.07 times more likely to perform moderate intensity PA and muscle-strengthening exercise, respectively, than female. Higher BMI (OR: 1.16), highest family income (OR: 3.98), and a caregiver who performed regular exercise (OR: 2.08) were positively associated with vigorous intensity PA of CCS. With increasing time after treatment completion, the probability of engaging in sedentary activity for less than 6 h per day decreased (OR = 0.89, 95% CI 0.79-1.00).

CONCLUSION

Korean adolescent CCS were physically inactive compared with control adolescents. Several sociodemographic factors such as sex, family income, caregiver PA, and obesity level were associated with PA behaviors of CCS.

IMPLICATIONS

Strategic effort would be needed to increase physical activity of childhood cancer survivors in adolescent period with consideration of various sociodemographic factors found in this study.

Health-related quality of life of children born to childhood cancer survivors in Germany

OBJECTIVE

Rising childhood cancer survival rates have increased the importance of health-related quality of life (HRQL) assessment. While survivors show comparable HRQL to peers, concerns that cancer treatment could impact the health of prospective children were reported. No previous publications address HRQL of childhood cancer survivor offspring.

METHODS

We assessed survivor offspring HRQL using the parental KINDL questionnaire. Matched-pair analysis was conducted with data from the general population (KiGGS study) using age, gender and education (1:1, n = 1206 cases). Multivariate analyses were conducted to detect the influence of parental diagnose and treatment on offspring HRQL.

RESULTS

Overall, within KINDL dimensions, survivors reported comparable to higher HRQL for their children than the general population. Survivor parents reported significantly (p < 0.001) higher psychological (86.7% vs. 83.0%, Cohen's d = 0.3) and self-esteem (79.1% vs. 73.3%, Cohen's d = 0.5) well-being scores for younger children (3-6-year-olds). As time since diagnosis increased, parents reported higher well-being scores. Accordingly, recently diagnosed survivors reported significantly lower psychological well-being scores (p = 0.28; OR = 0.457; 95% CI = 0.228-0.918) for their children. With increasing age, average HRQL scores decreased in both cohorts; yet, this drop was less pronounced for survivor offspring. The biggest difference between age groups (7-10- vs. 14-17-year-olds) was found for school-specific well-being (6.2-point drop in survivor offspring vs. 18.2-point drop in KiGGS offspring).

CONCLUSION

Comparable to higher parentally assessed HRQL was reported for survivor offspring compared to peers. These findings are reassuring and consistent with self-reported HRQL in childhood cancer survivors. Type of parental cancer diagnosis and treatment showed no negative impact on offspring HRQL.

Development and Usability Evaluation of a Facebook-Based Intervention Program for Childhood Cancer Patients: Mixed Methods Study

Background

Childhood cancers previously considered to be incurable now have 5-year survival rates up to 84%. Nevertheless, these patients remain at risk of morbidity and mortality from therapy-related complications. Thus, patient education and self-management strategies for promoting a healthy lifestyle are of tantamount importance for improving short- and long-term health outcomes. A Facebook-based “Healthy Teens for Soaam” (a Korean term for childhood cancers) program was developed to help improve knowledge and self-management practices of teens with cancer related to their disease and treatment.

Objective

The two-fold purpose of this usability study was (1) to describe the process of developing an 8-week Facebook-based intervention program for teens with cancer, and (2) to evaluate its usability to refine the program.

Methods

Multiple phases and methods were employed to develop and evaluate the usability of the program. Study phases included: (1) needs assessment through focus group interviews and qualitative content analysis, (2) development of module content, (3) expert review and feedback on module content, (4) Facebook-based program development, (5) usability evaluation by heuristic evaluation, (6) usability evaluation by targeted end-user testing, and (7) modification and final version of the program. Usability of the final version was confirmed through feedback loops of these phases.

Results

Based on 6 focus group discussion sessions, it was determined that teens with cancer were interested in seeing stories of successful childhood cancer cases and self-management after discharge, and preferred multimedia content over text. Therefore, each Facebook module was redesigned to include multimedia materials such as relevant video clips tailored for teens. Usability assessed by heuristic evaluation and user testing revealed several critical usability issues, which were then revised. Potential end users tested the final program and perceived it to be usable and useful for teens with cancer.

Conclusions

To our knowledge, “Healthy Teens for Soaam” is the first Facebook-based intervention program for teens with cancer. We actively worked with current childhood cancer patients and survivors to develop and improve this program, achieved good usability, and met the expressed needs and preferences of target end users. This 8-week Facebook-based educational program for teens with cancer, developed as the first step of an upcoming intervention study, will be useful for improving knowledge and self-management strategies of teens.

Barriers and enablers to physical activity and aerobic fitness deficits among childhood cancer survivors

BACKGROUND

Physical activity and aerobic fitness are modifiable risk factors for cardiovascular disease (CVD) after childhood cancer. How survivors engage in physical activity remains unclear, potentially increasing CVD risk. We assessed survivors' physical activity levels, barriers and enablers, fitness, and identified predictors of fitness and physical activity stage of change.

METHODS

Childhood cancer survivors (CCS; 8-18 years old) ≥1 year post-treatment were assessed for aerobic fitness (6-min walk test), used to extrapolate VO_2max , and body composition (InBody 570). Survivors self-reported physical activity to determine stage of change (Patient-Centered Assessment and Counselling for Exercise). Physical activity and fitness were compared with guidelines and CVD-risk cut-points (VO_2max  < 42 mL/kg/min: males; VO_2max  < 35 mL/kg/min: females). Multiple regression and mediator-moderator analysis were used to identify fitness predictors and stage of change.

RESULTS

One hundred two survivors (12.8 ± 3.3 years) participated (46% acute lymphoblastic leukaemia). Forty percent of males (VO_2max  = 43.3 ± 6.3 mL/kg/min) and 28% of females (VO_2max  = 36.5 ± 5.9 mL/kg/min) were in the CVD-risk category, while 25% met physical activity guidelines. Most prevalent physical activity barriers were fatigue (52%), preferring television instead of exercise (38%), and lacking time (34%). Predictive factors for reduced fitness included being older, female, higher waist-to-height ratio, higher screen time, and moderated by lower physical activity (r²  = 0.91, P < .001). Survivors with higher physical activity stage of change were male, lower body fat percentage, lower screen time, and lived with both parents (r = 0.42, P = .003).

CONCLUSION

Aerobic fitness and physical activity of CCS is low compared with population norms, potentially increasing CVD risk. Addressing physical activity barriers and enablers, including reducing screen time, could promote regular physical activity, reducing CVD risk.

Health Promoting Lifestyle Among Israeli Adult Survivors of Childhood Cancer

Background: Childhood cancer survivors are at risk for recurrence of their primary cancer as well as other secondary site cancers. The survivors are also at increased risk for long-term effects such as chronic illnesses. Health promoting lifestyles are therefore especially important for childhood cancer survivors. The purpose of the study was to describe the health promoting behaviors of childhood cancer survivors and to determine whether these behaviors are associated with demographic and clinical characteristics. This is a descriptive-comparative study that took place in an oncology follow-up clinic in Israel. Sample: Seventy-seven childhood cancer survivors. Tools: Health Promoting Lifestyle Profile 2, questionnaire (interpersonal relationships, spiritual growth, physical activity, nutrition, health responsibility, and stress management), and smoking and alcohol consumption and a demographic–clinical questionnaire. The mean item score was moderate-high. Survivors scored highest on interpersonal relationships and spiritual growth while the lowest scoring activities were physical activity and nutrition. About 30% of the survivors abstained from smoking and alcohol consumption. Women, as opposed to men, were more likely to have higher scores related to nutrition and interpersonal relationships while singles as opposed to those who were married were found to have higher scores related to spiritual growth. Conclusions: Health behaviors associated with interpersonal relationships and spiritual growth were more likely to be performed compared to physical activity, good nutrition, and decreased smoking and alcohol consumption. Special attention should be placed on promoting physical activity and good nutrition among survivors of childhood cancer.

Obesity in Childhood Cancer Survivors: Call for Early Weight Management

A high prevalence of obesity and cardiometabolic conditions has been increasingly recognized in childhood cancer survivors. In particular, survivors of pediatric acute lymphoblastic leukemia have been found to be at risk of becoming overweight or obese early in treatment, with increases in weight maintained throughout treatment and beyond. Nutrition plays an important role in the etiology of obesity and cardiometabolic conditions and is among the few modifiable factors that can prevent or delay the early onset of these chronic conditions. However, nutritional intake in childhood cancer survivors has not been adequately examined and the evidence is built on data from small cohorts of survivors. In addition, the long-term impact of cancer diagnosis and treatment on survivors' nutritional intake as well as how survivors' nutritional intake is associated with chronic health conditions have not been well quantified in large-scale studies. Promoting family-based healthy lifestyles, preferably at a sensitive window of unhealthy weight gain, is a priority for preventing the early onset of obesity and cardiometabolic conditions in childhood cancer survivors.

Understanding the Health Behaviors of Survivors of Childhood and Young-Adult Cancer: Preliminary Analysis and Model Development

The current study presents preliminary correlational data used to develop a model depicting the psychosocial pathways that lead to the health behaviors of survivors of childhood and young-adult cancer. Data collected from a sample of 18- to 30-year-old cancer survivors (n = 125) was used to examine the relations among interpersonal support and nonsupport, personal agency, avoidance, depressive symptoms and self-efficacy as they related to health behaviors. The outcome measures examined included tobacco and alcohol use, diet, exercise, sunscreen use, medication compliance and follow-up/screening practices. Correlational analyses revealed a number of significant associations among variables. Results are used to inform the development of a health behavior model. Implications for health promotion and survivorship programming are discussed, as well as directions for future research.

Health Behaviors of Childhood Cancer Survivors

There has been a dramatic increase in the number of childhood cancer survivors living to an old age due to improved cancer treatments. However, these survivors are at risk of numerous late effects as a result of their cancer therapy. Engaging in protective health behaviors and limiting health damaging behaviors are vitally important for these survivors given their increased risks. We reviewed the literature on childhood cancer survivors’ health behaviors by searching for published data and conference proceedings. We examine the prevalence of a variety of health behaviors among childhood cancer survivors, identify significant risk factors, and describe health behavior interventions for survivors.

Perceptions of risk among childhood and young adult cancer survivors who smoke

PURPOSE

Despite the fact that childhood and young adult cancer survivors are at increased risk for chronic health problems as a result of their cancer treatment, many use tobacco, thereby increasing their risks. Perceptions of risk related to tobacco use can be targeted for interventions aimed at improving health behaviors for childhood, adolescent, and young adult cancer survivors. Understanding the covariates of perceptions of health risks among young adult survivors who smoke will help to determine targets for intervention.

METHOD

Three hundred seventy-four participants who were diagnosed with cancer prior to age 35, currently between 18 and 55 years of age, and current smokers were recruited as part of a larger smoking cessation study, Partnership for Health-2 (PFH-2). Data were collected by telephone survey.

RESULTS

Overall, women had the highest perception of risk for serious health problems, a second cancer, and heart problems. Additionally, those participants who were dependent on nicotine endorsed that they were at higher risk of serious health problems and second cancers, but not heart problems. Finally, Hodgkin lymphoma survivors reported that they were at increased risk for second cancers and heart problems compared to their “healthy” peers.

CONCLUSION

Young adult cancer survivors who smoke correctly perceived some of their increased health risks. Additional motivation and education is needed for those young adult cancer survivors who perceive their increased health risks yet continue to smoke. Further education is needed for young survivors so they have a fully appropriate sense of risk, especially as it relates to their tobacco use.

Nutritional Counseling in Survivors of Childhood Cancer: An Essential Component of Survivorship Care

There is a growing body of evidence suggesting that nutritional status during treatment for cancer has a significant impact on treatment-related toxicities and outcomes among children and adolescents with cancer. The effects of nutritional status appear to extend into survivorship with a large proportion of survivors at risk for a variety of nutrition-related morbidities. The influence of dietary intake on overall treatment outcomes and long-term morbidities is largely unknown. In adults, evidence suggests that greater adherence to cancer prevention dietary guidelines improves long-term health outcomes among survivors of cancer. Surveys describing dietary intake among survivors of childhood cancer have found that most survivors are not meeting the recommended guidelines for many dietary nutrients and this may have an unfavorable effect on nutrition-related outcomes. However, more research is needed in this area so that well-designed clinical trials may be developed and tested. This review presents an overview of the existing literature describing dietary intake among survivors of childhood cancer, the clinical implications of reported dietary behaviors among survivors, and identifies areas for future research.

Decline in physical activity level in the Childhood Cancer Survivor Study cohort

BACKGROUND

We aimed to identify demographic and health-related predictors of declining physical activity levels over a four-year period among participants in the Childhood Cancer Survivor Study.

METHODS

Analyses included 7,287 ≥5-year childhood cancer survivors and 2,107 siblings who completed multiple follow-up questionnaires. Participants were classified as active if they met the Centers for Disease Control and Prevention guidelines for physical activity. Generalized linear models were used to compare participants whose physical activity levels declined from active to inactive over the study to those who remained active. In addition, selected chronic conditions (CTCAE v4.03 Grade 3 and 4) were evaluated as risk factors in an analysis limited to survivors only.

RESULTS

The median age at last follow-up among survivors and siblings was 36 (range, 21-58) and 38 (range, 21-62) years, respectively. The rate of decline did not accelerate over time among survivors when compared with siblings. Factors that predicted declining activity included body mass index ≥30 kg/m(2) [RR = 1.32; 95% confidence interval (CI), 1.19-1.46, P < 0.01], not completing high school (RR = 1.31; 95% CI, 1.08-1.60, P < 0.01), and female sex (RR = 1.33; 95% CI, 1.22-1.44, P < 0.01). Declining physical activity levels were associated with the presence of chronic musculoskeletal conditions (P = 0.034), but not with the presence of cardiac (P = 0.10), respiratory (P = 0.92), or neurologic conditions (P = 0.21).

CONCLUSIONS

Interventions designed to maximize physical activity should target female, obese, and less educated survivors. Survivors with chronic musculoskeletal conditions should be monitored, counseled, and/or referred for physical therapy.

IMPACT

Clinicians should be aware of low activity levels among subpopulations of childhood cancer survivors, which may heighten their risk for chronic illness.

Health-related quality of life, lifestyle behaviors, and intervention preferences of survivors of childhood cancer

PURPOSE

Childhood cancer survivors (CCSs) are at increased risk for poor health-related quality of life (HRQOL) and chronic health conditions-both of which can be exacerbated by unhealthy lifestyle behaviors. Developing a clearer understanding of the associations between HRQOL, lifestyle behaviors, and medical and demographic variables (e.g., age/developmental stage at time of diagnosis) is an important step toward developing more targeted behavioral interventions for this population.

METHOD

Cross-sectional questionnaires were completed by 170 CCSs who were diagnosed with leukemia, lymphoma, sarcoma, or a cancer of the central nervous system (CNS) and treated at a comprehensive cancer center between 1992 and 2007. Questionnaires addressed weight status, lifestyle behaviors, aspects of HRQOL, and intervention preferences.

RESULTS

Adolescent and young adult survivors (AYAs) and survivors of CNS tumors or lymphoma reported significantly (p < .05) poorer HRQOL across multiple domains compared to those diagnosed at an earlier age, survivors of leukemia or sarcoma, and healthy populations. A significant proportion also failed to meet national recommendations for dietary intakes (39-94 %) and physical activity (65 %). Female survivors reported poorer physical functioning and consumed less dietary fiber and fruits and vegetables than did male survivors. They also expressed the strongest interest in participating in diet and exercise interventions.

CONCLUSION

Findings support the premise that females, AYAs, and survivors of cancers of the CNS or lymphoma are "at risk" subgroups within the CCS population for poor dietary practices, sedentary behaviors, and poor HRQOL. Future research should focus on developing diet and PA interventions to improve HRQOL that target these groups.

IMPLICATIONS FOR CANCER SURVIVORS

Greater consideration of the role of gender, developmental stage, and the HRQOL challenges facing CCSs may help researchers to develop targeted behavioral interventions for those who stand to benefit the most.

Children's Oncology Group's 2013 blueprint for research: behavioral science

Behavioral science has long played a central role in pediatric oncology clinical service and research. Early work focused on symptom relief related to side effects of chemotherapy and pain management related to invasive medical procedures. As survival rates improved, the focused has shifted to examination of the psychosocial impact, during and after treatment, of pediatric cancer and its treatment on children and their families. The success of the clinical trials networks related to survivorship highlights an even more critical role in numerous domains of psychosocial research and care. Within the cooperative group setting, the field of behavioral science includes psychologists, social workers, physicians, nurses, and parent advisors. The research agenda of this group of experts needs to focus on utilization of psychometrically robust measures to evaluate the impact of treatment on children with cancer and their families during and after treatment ends. Over the next 5 years, the field of behavioral science will need to develop and implement initiatives to expand use of standardized neurocognitive and behavior batteries; increase assessment of neurocognition using technology; early identification of at-risk children/families; establish standards for evidence-based psychosocial care; and leverage linkages with the broader behavioral health pediatric oncology community to translate empirically supported research clinical trials care to practice.

Prospectively examining physical activity in young adult survivors of childhood cancer and healthy controls

BACKGROUND

This study compares young adult survivors of childhood cancer (YASCC) and young adults without a history of serious illness/injury on physical activity levels and examines psychological predictors of physical activity in survivors over a 2-month period.

PROCEDURE

YASCC participants (n = 117) and healthy controls (n = 148), ages 18-30, recruited during cancer survivorship clinic or primary care clinics completed self-report measures of physical activity, health problems, psychological distress, and health beliefs (Health Perceptions, Satisfaction with Healthcare, Cognitive Competence, and Autonomy). Survivorship providers completed ratings of health problems and treatment intensity for survivors.

RESULTS

Survivors had significantly lower levels of physical activity than controls. Family income, survivor-reported health problems and less positive health beliefs were associated with lower rates of physical activity. Provider-reported survivor health problems and ratings of cancer treatment intensity were not related to survivor physical activity. Less positive survivor beliefs about their cognitive competence predicted survivor physical activity 2 months later after accounting for other pertinent demographic, medical and psychological variables.

CONCLUSIONS

YASCC were significantly less active than healthy controls. YASCC with more self-identified health problems and negative beliefs about their cognitive competence were less physically active. Beliefs about their health and cognitive competencies may be viable areas for assessment and intervention in order to promote increased engagement in physical activity.

Physical Activity in Child and Adolescent Cancer Survivors: A Review

Childhood cancer survivors are at increased risk for future health problems. As such, physical activity (PA) has been targeted as a health promotion priority in child and adolescent cancer survivors. Research indicates that a large portion of pediatric survivors do not meet PA recommendations. Using Bronfenbrenner's ecological theory as a framework, this review presents a conceptual model to explain child and adolescent survivors' PA. The model considers predictors of PA across six domains: (1) demographic; (2) medical; (3) cognitive/emotional; (4) behavioral; (5) social/cultural; and (6) environmental. A structured literature review found 14 empirical articles examining those predictors of PA among child and adolescent cancer survivors. Much existing research is cross-sectional, but suggests multiple factors work together to encourage or discourage PA among survivors of child/adolescent cancer. The conceptual model, which is based in empirical findings to date, can be used to understand the process through which PA is promoted and maintained, to inform the development of empirically-supported clinical interventions, and to guide future research objectives and priorities.

Do Childhood Cancer Survivors Meet the Diet and Physical Activity Guidelines? A Review of Guidelines and Literature

Despite advances in cancer treatment, childhood cancer survivors are at higher risk of developing chronic health conditions than peers who have not had cancer. Being overweight or obese adds to the already elevated risk of cardiovascular diseases and metabolic abnormalities. Diet and physical activity are modifiable behaviors that reduce obesity risk and have been shown to improve cancer survival in adult cancer survivors. Specific guidelines have been developed for cancer survivors that provide advice on nutrition, physical activity and weight management following cancer diagnosis and treatment. In this review, we report on existing nutrition and physical activity guidelines for cancer survivors, supplemented by available literature on diet and physical activity status of childhood cancer survivors and their associations with health-related outcomes. The 2012 American Cancer Society (ACS) and the 2008 Children’s Oncology Group (COG) guidelines provide similar advice on diet but the ACS guidelines also offer specific advice on physical activity and weight management. Thirty-one observational studies and 18 intervention trials published prior to June 2012 that met the inclusion criteria were reviewed. Results suggest that a high proportion of childhood cancer survivors had poor adherence to dietary and physical activity guidelines. Although findings from existing intervention trials are preliminary due to small sample size, available evidence suggests that exercise intervention is safe and feasible for patients and survivors of childhood cancer. Childhood cancer survivors should be encouraged to engage in physical activity, adopt a healthy diet, and maintain a healthy weight throughout cancer survivorship.

Persistent cigarette smoking and other tobacco use after a tobacco-related cancer diagnosis

INTRODUCTION

People who continue to smoke after a cancer diagnosis have an increased risk for recurrences or development of new malignancies. These risks may be even higher among tobacco-related cancer survivors (TRCS). We describe tobacco use behaviors among TRCS, other cancer survivors, and people without a history of cancer.

METHODS

We used 2009 Behavioral Risk Factor Surveillance System data to describe demographic characteristics, smoking history, current smoking prevalence, and smokeless tobacco use among TRCS, other cancer survivors, and people without a history of cancer (cigarette smoking and smokeless tobacco use were calculated after adjusting for age, sex, race, and insurance status). Tobacco-related cancers were defined as lung/bronchial, pharyngeal, laryngeal, esophageal, stomach, pancreatic, kidney/renal, urinary bladder, cervical, and acute myeloid leukemia.

RESULTS

A total of 20 % of all cancer survivors were TRCS. TRCS were primarily female (68 %) and white (78 %). Smoking prevalence was higher among TRCS (27 %) compared with other cancer survivors (16 %) and respondents without a history of cancer (18 %). Smokeless tobacco use was higher among respondents without a history of cancer (4 %) compared with TRCS (3 %) and other cancer survivors (3 %).

CONCLUSIONS

The self-reported smoking prevalence among TRCS is higher than among other cancer survivors and people without a history of cancer. Targeted smoking prevention and cessation interventions are needed for cancer survivors, especially those diagnosed with a tobacco-related cancer.

IMPLICATIONS FOR CANCER SURVIVORS

We recommend all cancer survivors be made aware of the health risks associated with smoking after a cancer diagnosis, and smoking cessation services be offered to those who currently smoke. We provide the first population-based report on demographic characteristics and tobacco use behaviors among self-reported tobacco-related cancer survivors.

Dietary intake after treatment in child cancer survivors

BACKGROUND

Childhood cancer survivors (CCS) are at increased risk of complications such as obesity, diabetes, and osteoporosis which have the potential to, in part, be controlled with dietary interventions. To allow the development of appropriate dietary interventions for younger cancer survivors data on their dietary intake as well as information on parental nutrition views and practices need to be assessed.

PROCEDURE

Dietary intake of 50 CCS was assessed with a 3-day food diary (parent report). Parent child feeding practices were assessed with the Child Feeding Questionnaire (CFQ). Historical and anthropometric data was extracted from medical records. Survivors were less than 13 years old and less than 5 years after treatment completion.

RESULTS

Twenty percent of participating CCS was overweight or obese and 54% were consuming above their estimated energy requirements. Fifty, 32% and 44% of children did not meet requirements for folate, calcium, and iron respectively. There was a significant trend for increasing BMI percentiles from diagnosis to time of assessment (56.29 vs. 67.17, P = 0.01). Results from the CFQ showed that parents were more likely to monitor (3.99) and use a restrictive form of parenting (3.43) to control their child's food intake rather than pressure their child to eat (2.77) (P = 0.001).

CONCLUSION

This group displayed excessive energy intake (kilojoules) and poor dietary habits. Parents' restrictive feeding style may be contributing to these habits. Early interventions targeting the dietary intake of young survivors and associated parent feeding practices may prevent some of the deleterious long-term effects associated with childhood cancer therapy.

Risk factors for smoking among adolescent survivors of childhood cancer: a report from the Childhood Cancer Survivor Study

BACKGROUND

Few studies have examined risk factors for smoking among adolescent survivors of childhood cancer. The present study reports on the rate of smoking and identifies factors associated with smoking in a sample of adolescent survivors from the Childhood Cancer Survivor Study (CCSS).

PROCEDURE

Participants included 307 adolescent survivors and 97 healthy siblings (ages 14-20) who completed a self-report survey of health, quality of life, and health behaviors.

RESULTS

Smoking rates did not differ significantly between survivor and sibling groups (ever smokers: 28% vs. 33%, recent smokers: 10% vs. 9%, respectively). Ever smoking was significantly associated with peer smoking, smokers in the household, binging, suicidal behavior, and no history of CRT. There were significant interactions of peer smoking with gender and CRT for ever smoking and with binging for recent smoking. Recent smoking was more likely for survivors with other household smokers (RR=2.24, CI=1.21-4.16), past suicidality (RR=1.89, CI=1.00-3.56), and no CRT (RR=2.40, CI=1.12-5.17). Among survivors with few smoking friends, ever smoking was more likely for survivors with no CRT (RR=4.47, CI=1.43-13.9), and recent smoking was more likely among survivors who binged (RR=3.37, CI=1.17-9.71).

CONCLUSIONS

Despite the health risks associated with survivorship, nearly one in three adolescent survivors of childhood cancer has smoked. Exposure to other smokers, in particular, appears to increase the likelihood of smoking for some survivors. Providing smoking cessation programs targeted to family members, helping survivors choose non-smoking friends, and teaching ways to resist smoking influences from peers may be important pathways for smoking prevention with adolescent survivors.

Social, demographic, and medical influences on physical activity in child and adolescent cancer survivors

OBJECTIVE

This study evaluated associations between social, environmental, demographic, and medical predictors, and child and adolescent survivors' physical activity (PA).

METHODS

A structured telephone survey was conducted with 105 caregiver-survivor (aged 8-16 years) pairs and 36 caregivers of younger survivors (aged 6-7 years) alone. Participants completed measures assessing survivor PA and proposed predictors of PA including demographic, medical, social, and environmental influences.

RESULTS

Social influences, including family PA, family support for PA, and peer support for PA, emerged as unique predictors of survivor PA. These variables predicted PA after controlling for demographic and medical factors. Child survivors' PA was more strongly predicted by family influences while adolescent survivors' PA was more strongly influenced by family and peer influences.

CONCLUSIONS

Child and adolescent survivors' PA is strongly influenced by social factors. This finding parallels results with healthy children. PA interventions should focus on family and peer support to increase survivors' PA behaviors.

Who decides? Decision making and fertility preservation in teens with cancer: a review of the literature

PURPOSE

The knowledge that cancer treatment may impair fertility in pediatric populations is an emerging aspect of quality of life in this population. However, decision making and use of fertility preservation (FP) among adolescent cancer patients and their families has not been well studied. This review summarizes the available published data on aspects of decision making and FP in adolescent cancer patients.

METHODS

An electronic search was performed to identify peer-reviewed studies published between 1999 and 2009 using key Medical Subject Heading terms and inclusion criteria. Inclusion criteria limited eligible studies to those that focused on adolescent decision making in cancer treatment or FP, fertility concerns in pediatric oncology, capacity for decision making, and health decision making in pediatrics. Studies that did not meet at least one of these criteria were excluded.

RESULTS

A total of 29 articles were reviewed and summarized. Three categories of results were seen: a focus on adolescent decision making in oncology, decision making in chronic illness, and decision making in cancer-related infertility and preservation.

CONCLUSION

Most of the studies showed that adolescents have a strong desire to participate in decisions related to their cancer treatment and many have concerns regarding their future fertility, although barriers often prevented these discussions. More research is needed to explore the role of teenagers and parents in decisions about fertility in relation to cancer treatment.

Diet and physical activity in childhood cancer survivors: a review of the literature

Treatment advances have led to a growing population of childhood cancer survivors. Many are at risk for developing treatment-related late effects. Diet and physical activity may affect levels of health risk. A number of papers have examined these behaviors in childhood cancer survivors. The purpose of this study was to provide a review and summary of the published studies in the areas of diet, physical activity, and related interventions among childhood cancer survivors. A systematic search was conducted for studies published prior to October 2009. Descriptive and intervention studies that included survivors of childhood cancers and a measurement of diet and/or physical activity were reviewed. Twenty-six manuscripts met criteria: ten addressed diet; 20 addressed physical activity, and six included intervention studies. Results suggest that childhood cancer survivors engage in health-promoting activities at rates comparable to the general population. Behavioral interventions have mostly targeted physical activity. Results, overall, are not encouraging, due primarily to difficulties recruiting and retaining participants. Although more rigorous studies are needed, recommendations for health-promoting behaviors should be a regular topic of discussion between health care providers and their childhood cancer survivor patients.

Adolescent cancer survivors' smoking intentions are associated with aggression, attention, and smoking history

INTRODUCTION

The present study examines behavioral and psychosocial factors associated with smoking intentions and experimentation among adolescent survivors of pediatric cancer.

METHODS

Adolescent survivors of brain tumor and acute lymphoblastic leukemia (n  =  99) provided information about their smoking histories and their intentions to smoke in the future. Behavior rating scales were completed by survivors, parents, and teachers.

RESULTS

Past experimentation with smoking and higher levels of self-reported aggression were associated with intentions to smoke in the future (OR  =  4.18, 95% CI 1.02-17.04, and OR  =  1.08, 95% CI 1.01-1.15, respectively), while teacher-ratings of inattention in the classroom were negatively associated with intentions to smoke (OR  =  0.94, 95% CI.88-.99), all p  < .05. Experimentation with smoking was more likely among older survivors (OR  =  1.76, 95% CI 1.16-2.66, p  < .01) and those whose parents had divorced (OR  =  4.40, 95% CI 1.21-16.06, p  < .05).

DISCUSSION

A concerning minority of adolescent survivors have clear intentions to smoke, a behavior that adds to their overall health risk. Smoking intentions and experimentation are important precursors to regular smoking. Prevention efforts are needed to interrupt the progression from intentions and experimentation to established smoking and nicotine dependence in this medically vulnerable population.

IMPLICATIONS FOR CANCER SURVIVORS

Assessment of an adolescent's history of parental divorce, past experimentation with smoking, and aggressive behavior will identify those survivors who are likely to consider smoking in the future. Screening for these characteristics will allow clinicians to be more vigilant in health promotion.

Health and risk behaviors in survivors of childhood acute myeloid leukemia: a report from the Children's Oncology Group

BACKGROUND

Survivors of childhood acute myeloid leukemia (AML) face increased risks of chronic disease and secondary malignancies. Substance exposure may compound these risks.

PROCEDURES

Participants were diagnosed with AML at <21 years of age and survived > or =5 years following diagnosis. All underwent chemotherapy alone or followed by autologous BMT (chemo +/- autoBMT) or underwent allogeneic BMT (alloBMT) if an HLA-matched related donor was available. Survivors completed a health questionnaire and a Youth Risk Behavior Survey (YRBS).

RESULTS

Of eligible survivors, 117 were > or =18 years of age and completed a YRBS. Survivors were a mean age of 10 years at diagnosis and 24 years at interview. Of the substance exposures assessed by YRBS, tobacco, alcohol, and marijuana were most common. Twenty-two percent (22%) had smoked cigarettes in the last 30 days. One-quarter (25%) reported binge drinking in the last month. None of these exposures varied by treatment group. Less than 10% of survivors reported cocaine, heroin, or methamphetamine use. Men were more likely to report high substance exposure (P = 0.004). Sadness/suicidality score was associated with cancer-related anxiety (P = 0.006) and multiple health conditions (P = 0.006).

CONCLUSIONS

This analysis reveals exposure to tobacco, alcohol, and marijuana in young adults with few differences based on treatment received. Survivors with cancer-related anxiety or multiple health conditions were more likely to report sadness/hopelessness.

Establishing the predictive validity of intentions to smoke among preadolescents and adolescents surviving cancer

PURPOSE

A significant proportion of adults surviving childhood cancer are smokers. Although these estimated rates of smoking are slightly lower than those in the US population, they remain alarmingly high for this high-risk group. The purpose of this study was to examine the predictive validity of adolescent self-reported smoking intentions for later smoking among childhood cancer survivors.

PATIENTS AND METHODS

Baseline tobacco intentions were collected from 119 nonsmoking cancer survivors, age 10 to 18 years, who participated in a tobacco-based clinical trial during the late 1990s. Follow-up smoking status was systematically collected annually up to 10 years postintervention (median follow-up, 6.0 years; interquartile range, 3.0 to 6.9 years) as part of clinical survivorship care.

RESULTS

Twenty-seven participants (22.7%) subsequently initiated tobacco use within 5 years of study enrollment. The 5-year cumulative incidence was 29.8% +/- 6.0% for those who were susceptible to smoking compared with 12.8% +/- 5.4% for those who were committed never smokers (P = .022). Past use (P < .001) and having friends who smoked (P = .038) were also associated (univariate model) with tobacco initiation, and there was a trend for an association for older adolescents (P = .073). Every unit increase on the intentions scale was associated with a 17% increase in the risk for tobacco initiation (P = .002) after adjusting for age group and past tobacco use in a multivariable model.

CONCLUSION

Because early intentions to smoke are predictive of later tobacco use, survivors as young as 10 years of age who waver in their commitment to remain tobacco abstinent should be targeted for tobacco prevention interventions.

Design and recruitment of the Chicago Healthy Living Study: a study of health behaviors in a diverse cohort of adult childhood cancer survivors

BACKGROUND

Adult childhood cancer survivors are at higher risk for developing late medical effects related to their cancer treatments. Health-promoting behaviors may reduce the risk of some late effects and the severity of others. This article describes the design and recruitment of the Chicago Healthy Living Study (CHLS), an on-going study designed to examine the health behaviors and body mass index of minority adult childhood cancer survivors compared with nonminority survivors and noncancer controls.

METHODS

Survivors are identified by the hospital cancer registries at 5 treating institutions in the Chicago area; then, a multilevel recruitment plan will be implemented with the objective of enrolling 450 adult survivors of childhood cancer (150 in each racial/ethnic group). Simultaneously, 375 adult African-American, Hispanic, and non-Hispanic white noncancer controls (125 in each racial/ethnic group) living in the Chicago area will be recruited by using listed, targeted digit dialing. All participants will complete a 2-hour interview of questionnaires related to diet, physical activity, smoking, and associated mediators. Height and weight also will be measured.

CONCLUSIONS

The CHLS will provide important information on the health behaviors of adult minority childhood cancer survivors that can be used to inform the development of interventions to improve modifiable risks.

Contrasting parental perspectives with those of teenagers and young adults with cancer: comparing the findings from two qualitative studies

PURPOSE

To compare and contrast the issues raised in narrative data gathered from parents of teenagers and young adults with cancer with interview data gathered from young adults being treated for cancer.

METHODS

A narrative correspondence method elicited contributions from the parents of 28 young adults with cancer. In-depth qualitative interviews were undertaken with 28 young adults in treatment for cancer or soon after their treatment.

KEY RESULTS

The secondary analysis of the two data sets illuminates contrasting familial perspectives. While some of the topics raised by parents are also addressed by young people, their perspectives differ thus offering a 'mirror image' of the same issue. The contrast in priorities can contribute to stress within the family and can increase the danger of conflict over key decisions that may impact upon the health of the young adult with cancer.

CONCLUSIONS

If the potential conflicts are anticipated and understood and as a consequence handled with skill by professionals in the setting of care, this can benefit family relationships which can be thrown into crisis by the illness. It is thus important that a model of care that incorporates such an understanding is widely implemented in order to mitigate the negative impact on family dynamics when cancer is diagnosed in young adulthood.

Prevalence of multiple health-related behaviors in adolescents with cancer

OBJECTIVE

This preliminary study investigated prevalence rates of multiple health-related behaviors (ie, tobacco, alcohol, and other drug use; sexual risk-taking; nutrition/physical activity; overweight and dietary behaviors; sun safety) among 42 adolescents on active treatment for cancer, as compared with healthy adolescent norms.

METHODS

Health-related behaviors were assessed using the 2005 National Youth Risk Behavior Survey, for which healthy adolescent norms were publicly available.

RESULTS

Adolescents with cancer reported significantly lower current and lifetime rates of tobacco, alcohol, and other drug use; fruit/vegetable consumption; physical activity; and dietary behavior, in addition to lower rates of lifetime sexual intercourse, early-onset sexual intercourse, and alcohol/drug use before last sexual intercourse, compared with healthy peers. Among those who have previously engaged in sexual intercourse, there appeared to be a trend toward increased partners, current sexual activity, and lack of protection at last episode of sexual intercourse. Adolescents with cancer also reported significantly higher rates of television watching compared with healthy peers.

CONCLUSIONS

Adolescents on active treatment for cancer are engaging in multiple health-risk behaviors, including sedentary behavior, poor nutrition, lack of sun safety, and sexual risk-taking (eg, multiple partners, lack of protection at last sexual intercourse). Health promotion interventions are needed during active treatment to facilitate the acquisition of good health practices as adolescents transition into survivorship.

Predictors of health-harming and health-protective behaviors in adolescents with cancer

BACKGROUND

Given adolescent cancer survivors' increased susceptibility to late effects, it is imperative that we understand factors that influence their engagement in healthy and unhealthy behaviors. The purpose of this exploratory study was to identify significant predictors of health-harming and health-protective behaviors in adolescent cancer patients.

PROCEDURE

Forty-two adolescents (ages 12-19 years) currently on-treatment for cancer and their parents were recruited from outpatient pediatric cancer clinics. Adolescents completed a battery of questionnaires that assessed their health-behaviors, quality of life, and psychological distress, while parents completed a demographic questionnaire.

RESULTS

Regression analyses indicated that specific demographic, illness, and psychosocial variables significantly predicted health-harming and health-protective behaviors. Older adolescent age and unmarried parent status emerged as the best predictors of adolescent health-harming behaviors, whereas married parent status, increased adolescent time since diagnosis, increased adolescent-rated quality of life, and increased distress emerged as the best predictors of health-protective behaviors.

CONCLUSIONS

Demographic, illness, and psychosocial variables may help inform the development of interventions designed to promote the initiation and/or maintenance of good health practices among adolescents on-treatment for cancer. Interventions are needed that target health behaviors while adolescents are approaching treatment completion, in order to help facilitate the practice of good health practices in survivorship.

Follow-up care for young adult survivors of cancer: lessons from pediatrics

INTRODUCTION

Recent advances in treatment of childhood cancer have resulted in overall survival rates approaching 75%, but approximately two-thirds experience late-effects related to the disease or treatment. Consequently, recommendations for comprehensive follow-up have been made. As the number of survivors of adult cancers increase, similar concerns about how to provide follow-up and achieve optimal quality of life are being raised. In this paper we propose that management of cancer survivors diagnosed in young adulthood (18-45 years) could benefit from experience gained treating survivors of childhood cancer.

MATERIALS AND METHODS

We reviewed research relating to differences in survival rates and late-effects; current arrangements for follow-up; effectiveness; and problems in organization of follow-up separately for survivors of child and adult cancers.

RESULTS

A number of models of follow-up were identified. Rationale for follow-up included early identification and treatment of second cancer and late-effects, health promotion and screening. Increasing numbers of survivors and range of late-effects were identified as problems in organizing services. A possible solution is risk-stratified follow-up, currently being developed in pediatrics.

CONCLUSIONS

New models of follow-up are needed that take account of financial costs for health services and survivors' concerns about their current and future health. Implications for continuing refinement of treatment protocols must be an integral part of the service.

IMPLICATIONS FOR CANCER SURVIVORS

International standards are needed to ensure all survivors have access to expert follow-up care and can benefit from new information that might lead to earlier treatment of late-effects.

Alcohol consumption patterns and risk factors among childhood cancer survivors compared to siblings and general population peers

AIMS

This study describes alcohol consumption among adult survivors of pediatric cancer compared to sibling controls and a national sample of healthy peers. Risk factors for heavy drinking among survivors are described.

DESIGN, SETTING AND PARTICIPANTS

Cross-sectional data were utilized from the Childhood Cancer Survivor Study including adult survivors of pediatric cancer (n = 10 398) and a sibling cohort (n = 3034). Comparison data were drawn from the National Alcohol Survey (n = 4774).

MEASUREMENT

Alcohol consumption, demographic, cancer diagnosis, treatment and psychosocial factors were measured.

FINDINGS

Compared to peers, survivors were slightly less likely to be risky [adjusted odds ratio (ORadj) = 0.9; confidence interval (CI) 0.8-1.0] and heavy drinkers (ORadj = 0.8; CI 0.7-0.9) and more likely to be current drinkers. Compared to siblings, survivors were less likely to be current, risky and heavy drinkers. Risk factors for survivors' heavy drinking included being age 18-21 years (ORadj = 2.0; 95% CI 1.5-2.6), male (ORadj = 2.1; 95% CI 1.8-2.6), having high school education or less (ORadj = 3.4; 95% CI 2.7-4.4) and drinking initiation before age 14 (ORadj = 6.9; 95% CI 4.4-10.8). Among survivors, symptoms of depression, anxiety or somatization, fair or poor self-assessed health, activity limitations and anxiety about cancer were associated with heavy drinking. Cognitively compromising treatment, brain tumors and older age at diagnosis were protective.

CONCLUSIONS

Adult survivors of childhood cancer show only a modest reduction in alcohol consumption compared to peers despite their more vulnerable health status. Distress and poorer health are associated with survivor heavy drinking. Screening for alcohol consumption should be instituted in long-term follow-up care and interventions among survivors and siblings should be established to reduce risk for early drinking.

Complementary and alternative therapy use in adult survivors of childhood cancer: a report from the Childhood Cancer Survivor Study

BACKGROUND

Little information is available on the use of complementary and alternative medicine (CAM) in long-term survivors of childhood and adolescent cancer.

PROCEDURE

The Childhood Cancer Survivor Study (CCSS) is a resource evaluating the long-term effects of cancer and associated therapies in 5-year survivors of childhood and adolescent cancer diagnosed between 1970 and 1986 before the age of 21 years. A survey of CAM use during the previous year was distributed in 2000-2001 and completed by 9,984 survivors and 2,474 sibling controls.

RESULTS

CAM use reporting was similar in cases (39.4%) and siblings (41.1%). Compared to female siblings, female survivors were more likely to use biofeedback (odds ratio (OR) = 3.3; 95% CI = 1.0-10.8) and hypnosis/guided imagery (OR = 3.2; 95% CI = 1.6-6.8); male survivors were more likely than male siblings to use herbal remedies (OR = 1.3; 95% CI = 1.1-1.6). Factors associated with CAM use in survivors included elevated scores on the brief symptom inventory (BSI)-18 (OR = 1.6; 95% CI = 1.3-1.9), prolonged pain (OR = 1.5; 95% CI = 1.3-1.7), and having seen a physician in the past 2 years (OR = 1.6; 95% CI = 1.4-1.8). Survivors reporting low alcohol intake and excellent or good general health reported lower levels of CAM use (OR = 0.7; 95% CI = 0.7-0.8 and OR = 0.8; 95% CI = 0.7-0.9, respectively).

CONCLUSIONS

Survivors have a similar reported use of CAM compared to a sibling cohort. However, our data suggest that survivors turn to CAM for specific symptoms related to previous diagnosis and treatment. Future research is needed to determine whether CAM use reflects unmet health needs in this population.

Health-risk behaviors and health promotion in adolescent and young adult cancer survivors

A diagnosis of cancer during adolescence, a period characterized by experimentation and risk-taking behaviors, has the potential to derail critical developmental tasks required for successful transition into adulthood. Health professionals caring for adolescents and young adults have an opportunity to influence behavioral practices by correcting knowledge deficits, addressing factors that enhance the survivor's sense of vulnerability to health problems, and providing personalized health counseling that encourages the practice of health promoting behaviors. The approach to health counseling in childhood cancer survivors should consider their unique educational needs related to their cancer experience. Previous investigations of adolescent and young adult survivor health behavior indicate that survivors perceive themselves as more vulnerable to health problems than their peers without cancer and recognize a need to protect their health. However, these perceptions of health vulnerability do not always correlate with health promoting behavioral practices, suggesting that factors other than health perceptions should be investigated to motivate behavioral change. Very few studies have been undertaken to prospectively evaluate the effectiveness of health promotion programs in adolescent and young adult survivors of cancer. The scarcity of knowledge in the issue of health promotion after childhood cancer underscores the need for more research to define 1) the optimal timing of health counseling; 2) the influence of developmental status and neurocognitive function; 3) the most effective methods and venues for health education; 4) the feasibility and cost-effectiveness of health promotion strategies; and 5) psychosocial and economic impediments to practice of healthy behaviors.

Correlates of physical activity in young adult survivors of childhood cancers

PURPOSE/OBJECTIVES

To examine correlates of participation in regular physical activities among young adult survivors of childhood cancers.

DESIGN

Descriptive, correlational.

SETTING

Web-based survey.

SAMPLE

117 well-educated, predominately Caucasian survivors of various types of childhood cancers (-X age = 24 years).

METHODS

Participants completed four rating scales, a stages of change measure, and background questions. Logistic regression and graphical methods were used to examine relationships among physical activity correlates and physical activity.

MAIN RESEARCH VARIABLES

Physical activity stages of change, autonomous motivation, physical activity pros and cons, self-efficacy, and self-reported worries.

FINDINGS

More than 80% of participants reported that they were physically active. Survivors who were autonomously motivated and who perceived fewer cons to being physically active were more likely to report being active than survivors with lower autonomous motivation scores and higher physical activity cons scores. Worries about the present and future moderated the effect of physical activity cons on physical activity. The estimated probabilities of reporting being active for women and men changed as the collective contribution of autonomous motivation, physical activity cons, and worries varied from low to high values.

CONCLUSIONS

Engaging in physical activity willingly and without a sense of pressure (autonomous motivation), perceiving fewer cons to physical activity participation (cognitive appraisal), and worrying about the present and future (affective response) were important correlates of self-reported physical activity beyond the influence of gender.

IMPLICATIONS FOR NURSING

Interventions that promote autonomous motivation, decrease physical activity cons, and address present and future worries may increase physical activity in young adult cancer survivors and may have a greater impact on women than men.

Health behaviours in childhood cancer survivors: a systematic review

AIM

To review (1) prevalence and predictors of risk behaviours especially smoking and (2) values of interventions to reduce risk behaviours in childhood cancer survivors.

METHOD

A systematic search of four databases (OVID Medline (1966 to May week 2, 2006), CINAHL, EMBASE, and Pubmed (US Library of Medicine and National Institute of Health)) for articles published between January 1990 and May 2006.

RESULTS

Twenty-three eligible articles. Incidence of risk behaviours are comparable with, or lower than the general population and controls. Socio-demographic (age, socio-economic status, diagnosis, ethnic group) and psychological variables (perceived vulnerability) predict risk behaviour. Improved knowledge and awareness of vulnerability have been found after interventions, but no changes in health behaviours.

CONCLUSION

This review illustrates an optimistic picture of low participation in substance use amongst survivors, although based mainly on smoking. However, smoking might not be the major problem for survivors and attention must also be directed to other health behaviours including exercise and healthy diet.

Multiple behavioral risk factors among adolescent survivors of childhood cancer in the Survivor Health and Resilience Education (SHARE) program

BACKGROUND

Health-compromising behaviors among survivors of childhood cancer may increase their risks of cancer recurrence and the onset of chronic disease in adulthood. Regardless of whether such behaviors occur singly or in combination with one another, multiple behavioral risk factors must be identified and addressed early to promote better health outcomes within this special population. Adolescent survivors may be especially vulnerable, as reported rates of smoking and other risky behaviors are at or near levels of their healthy peers. The psychological literature suggests stress may play a role in risk behavior initiation and maintenance, including multiple behavioral risks, and that adolescent survivors are stress-prone. This report focuses on the prevalence and co-occurrence of three behavioral risk factors (cigarette use, insufficient physical activity, and non-adherence to sun protection recommendations) and describes stress-health behavior relationships in this special population.

PROCEDURE

All patients in this study (n = 75) were adolescent survivors of childhood cancer and completed a baseline assessment of their health behaviors and stress as part of a randomized controlled trial of health promotion.

RESULTS

Twenty-eight percent of the patients reported one of three risk factors, 12% reported two of three risk factors, and 7% reported all three risk factors. Non-adherence to sun protection was the single most common risk factor; physical inactivity and non-adherent sun protection were the most common co-occurring risk factors. Greater age and stress were significantly associated with the presence of more behavioral risk factors.

CONCLUSIONS

The evidence suggests interventions to reduce multiple health-compromising behaviors in these patients are warranted, and that efforts to address these patients' personal and family stress levels are important as well.

Predicting perceived vulnerability to tobacco-related health risks and future intentions to use tobacco among pediatric cancer survivors

OBJECTIVE

To examine predictors of perceived vulnerability to tobacco-related health risks and future intentions to use tobacco among pre-adolescents and adolescents previously treated for cancer.

METHODS

Written self-report measures of tobacco knowledge, perceived vulnerability, perceived positive value of tobacco use, past and present tobacco use, and intentions to use tobacco were completed by 103 cancer survivors, 10-18 years of age (51.5% males, 78.6% Caucasians). Patient reports of peer and parent tobacco use were also obtained.

RESULTS

Perceived vulnerability was influenced by demographic variables, knowledge, and gender-related past tobacco use. Fifty-seven percent of non-smoking survivors reported some intention to use tobacco. Survivors who perceived some positive value associated with tobacco use and who used tobacco in the past reported greater intentions for future tobacco use.

CONCLUSION

Modifiable cognitive-motivational variables directly associate with smoking-related outcomes among pediatric survivors of childhood cancer.

PRACTICE IMPLICATIONS

Preventive tobacco interventions with this vulnerable cohort are warranted and should inform about tobacco-related health risks and attempt to modify misperceptions of the positive value associated with tobacco use.

Uncertainty, Posttraumatic Stress, and Health Behavior in Young Adult Childhood Cancer Survivors

BACKGROUND

Young adult survivors of childhood cancer are at risk for medical late effects, some of which can be managed through health promotion behaviors. However, chronic uncertainty about the future can lead to the development of posttraumatic stress symptoms (PTSS) that can interfere with health promotion behaviors.

OBJECTIVES

To test a mediating model for the relationships among uncertainty, PTSS, and health promotion behaviors in young adult survivors of childhood cancer.

METHODS

The design was cross-sectional correlational. A convenience sample was used, and the data were collected using a mailed survey. Study measures included the Mishel Uncertainty in Illness Scale-Community Form, the Posttraumatic Stress Disorder Index, and the Health Promoting Lifestyle Profile II.

RESULTS

Forty-six (51.1%) of the eligible survivors responded to the invitation to participate in the study. The analysis was based on data from 45 survivors. The results show that the relationship between PTSS and health promotion behaviors was mediated by uncertainty.

DISCUSSION

Uncertainty is a suitable target for theory-based nursing interventions used to boost health promotion behaviors in young adult survivors of childhood cancer.

Adolescent survivors: a secondary analysis of a clinical trial targeting behavior change

BACKGROUND

The late effects of radiation and chemotherapy increase childhood cancer survivors' risk of chronic health problems. Survivors' behavior is important in modifying this risk, yet adolescent and young adult survivors fail to engage in important health-promoting behaviors and frequently practice high-risk behaviors. This secondary analysis re-evaluated a multi-component behavior-change intervention that had previously demonstrated no impact in adolescent survivors of childhood cancer.

PROCEDURE

The parent trial compared 132 adolescent survivors in the intervention arm with 135 in the standard-care arm at baseline and at 1 year for disease and treatment knowledge, perception of late effects risk, and the frequency of health-risk and health-protective behaviors (combined as a single summative measure). In contrast, the secondary analysis examined each of the 14 behaviors separately. Additionally, an analysis of covariance (ANCOVA) was conducted to examine the change in health behaviors while statistically controlling for age, gender, and the wide variation in baseline behaviors.

RESULTS

Knowledge (P = 0.038), breast self-examination (BSE) (P < or = 0.0001) and testicular self-examination (P = 0.004) increased, as did perceptions about the need to change behavior (P = 0.004) and the effort needed to stay healthy (P < or = 0.0001). In the treatment group, junk food consumption decreased (P = 0.052) and smoking abstinence was maintained (P = 0.088). Significant interactions between gender and treatment group were demonstrated.

CONCLUSIONS

Health-risk and health-protective behaviors cannot be effectively combined in a one-dimensional measure. Gender and age influence the impact of interventions targeting health behavior in survivors. Future trials should include observation of the patient-clinician encounter, more complex sampling methods, and pre-trial knowledge of the distribution of the study behaviors.

Brief report: social risk factors predict cigarette smoking progression among adolescents with asthma

OBJECTIVE

To compare smoking progression in adolescents with and without asthma and to compare their psychosocial risk factors.

METHODS

Participants were 1,507 adolescents with asthma and 1,507 healthy matched controls from Waves I and II of the Add Health Project assessed at baseline and again 1 to 2 years later at follow-up. Three levels of smoking progression (defined as smoking more frequently and/or intensely over time) were identified: (a) Late Experimenters (never smokers at baseline, ever smokers at follow-up), (b) Early Experimenters (ever smokers at baseline, current/current frequent smokers at follow-up), and (c) Early Smokers (current smokers at baseline, current frequent smokers at follow-up).

RESULTS

Twenty percent of adolescents experienced progression in their smoking behavior; those with and without asthma were equally likely to progress. Among adolescents who progressed, 37% were Late Experimenters, 42% were Early Experimenters, and 21% were Early Smokers. Exposure to friends who smoked was a consistent and powerful social risk factor for smoking progression among adolescents with asthma-more so than among adolescents without asthma. This effect was intensified among Late Experimenters by the presence of a positive history of parent smoking.

CONCLUSIONS

Findings underscore the importance of addressing cigarette smoking behavior and its social risk factors among adolescents with asthma in both clinical and public health contexts, during early adolescence, and through research on this topic.

Brief Report: Health Beliefs Among Survivors of Childhood Cancer

OBJECTIVE

To describe interest in cancer screening and tobacco-control procedures (nicotine-addiction susceptibility testing) among survivors of childhood cancer and to identify psychosocial modifying and readiness factors associated with survivors' interest, based on the children's health belief model.

METHODS

Twenty-eight survivor-mother dyads were interviewed as part of a preliminary study (mean age of survivors = 15.4 years at time of interview, 10.1 years at time of diagnosis, and 12.0 years at end of treatment); interviews consisted of well-validated self-report items and measures of health beliefs.

RESULTS

In sum, 57% and 61% of survivors were interested in screening and susceptibility testing, respectively. Survivors who rated themselves as more competent, more concerned about cancer, and more vulnerable to cancer were more interested in participating in screening. Regarding interest in nicotine-addiction susceptibility testing, survivors were more interested when they perceived greater vulnerability to the harm of smoking and when they had mothers who perceived themselves to be in better health.

CONCLUSIONS

Preliminary data suggest that psychosocial modifying and readiness factors are associated with survivors' interest in cancer screening and tobacco-control procedures and that additional research in this area is warranted.
