Childhood cancer survivors report preferring lifestyle interventions delivered in person rather than online: An adolescent and parent perspective. Pediatr Blood Cancer 2019; 66:e27922. [PMID: 31309668 DOI: 10.1002/pbc.27922] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2019] [Revised: 05/15/2019] [Accepted: 05/31/2019] [Indexed: 12/20/2022]
Abstract
BACKGROUND Maintaining a healthy lifestyle can protect adolescent survivors of pediatric cancer against chronic diseases such as obesity and cardiovascular disease. In this study, we examined the attitudes of adolescent survivors of pediatric cancer and their parents toward improving lifestyle behaviors after cancer treatment, including their preferences for intervention delivery and perceived barriers and benefits to healthy eating and exercise. METHODS We recruited adolescent survivors of childhood cancer aged 11-19 years and their parents, from two hospitals. Participants completed a questionnaire via mail or at routine oncology clinic visits. RESULTS Thirty-three adolescents (response rate 39%, mean age 15, 61% male) and 32 parents (representing 30 parent-child dyads) participated. Parents were significantly more interested in having their child participate in a lifestyle intervention than adolescents (41% of adolescents and 72% of parents, P = .012). Both groups preferred that the survivor receive lifestyle support face to face rather than online. Adolescents preferred to involve their friends (39% of adolescents and 19% of parents) whereas parents preferred to involve the family in a lifestyle intervention (15% of adolescents and 47% of parents, P = .006). Adolescents and their parents perceived a dislike of the taste of fruits and vegetables, fatigue, lack of motivation, and fear of injury as barriers to change. They perceived that keeping healthy and having more energy were benefits to participation. Participants indicated that interventions that provide face-to-face personal training and dietary education at a local gym would be well accepted. CONCLUSIONS Adolescents who have had cancer in childhood have a preference for face-to-face contact with health professionals to overcome the barriers to participation in a lifestyle intervention.

Abstract
BACKGROUND Parental empowerment signifies parents' sense of confidence in managing their children, interacting with services that their children use and improving child care services. High empowerment is associated with parents' resilience to demands and their confidence to make decisions and take actions that positively affect their families. Most families with children access various healthcare and education services. Professionals working in these services are therefore ideally placed to reinforce parental empowerment. However, little is known about the characteristics associated with parental empowerment within a generic sample of parents or in the context of basic child care services. AIM The aim of this study was to assess how family characteristics are associated with maternal and paternal empowerment in the family, in service situations and in the service system. METHOD Parental empowerment was measured among 955 parents (mothers = 571; fathers = 384) of children aged 0-9 years using the Generic Family Empowerment Scale. Family characteristics were assessed through questions on children, parents and the life situation. Associations between empowerment and family characteristics were evaluated using one-way analysis of variance and t-test. Parental empowerment was predicted by multiple linear regression analysis. RESULTS Parents' concerns related to their parenting, such as whether they possessed sufficient skills as a parent or losing their temper with children, as well as experiences of stress in everyday life, were negatively associated with all dimensions of maternal and paternal empowerment. Both determinants were more common and more significant in empowerment than child-related problems. CONCLUSION Promoting parental self-confidence and providing appropriate emotional and concrete support for everyday functioning may reinforce parental empowerment, thereby enhancing families' well-being and coping, as well as improving their access to required services and timely support. Finally, it may facilitate the provision of better services to all families.

Abstract
OBJECTIVE To investigate the association between use of combined oral contraceptives and risk of venous thromboembolism, taking the type of progestogen into account. DESIGN Two nested case-control studies. SETTING General practices in the United Kingdom contributing to the Clinical Practice Research Datalink (CPRD; 618 practices) and QResearch primary care database (722 practices). PARTICIPANTS Women aged 15-49 years with a first diagnosis of venous thromboembolism in 2001-13, each matched with up to five controls by age, practice, and calendar year. MAIN OUTCOME MEASURES Odds ratios for incident venous thromboembolism and use of combined oral contraceptives in the previous year, adjusted for smoking status, alcohol consumption, ethnic group, body mass index, comorbidities, and other contraceptive drugs. Results were combined across the two datasets. RESULTS 5062 cases of venous thromboembolism from CPRD and 5500 from QResearch were analysed. Current exposure to any combined oral contraceptive was associated with an increased risk of venous thromboembolism (adjusted odds ratio 2.97, 95% confidence interval 2.78 to 3.17) compared with no exposure in the previous year. Corresponding risks associated with current exposure to desogestrel (4.28, 3.66 to 5.01), gestodene (3.64, 3.00 to 4.43), drospirenone (4.12, 3.43 to 4.96), and cyproterone (4.27, 3.57 to 5.11) were significantly higher than those for second generation contraceptives levonorgestrel (2.38, 2.18 to 2.59) and norethisterone (2.56, 2.15 to 3.06), and for norgestimate (2.53, 2.17 to 2.96). The number of extra cases of venous thromboembolism per year per 10,000 treated women was lowest for levonorgestrel (6, 95% confidence interval 5 to 7) and norgestimate (6, 5 to 8), and highest for desogestrel (14, 11 to 17) and cyproterone (14, 11 to 17). CONCLUSIONS In these population based, case-control studies using two large primary care databases, risks of venous thromboembolism associated with combined oral contraceptives were, with the exception of norgestimate, higher for newer drug preparations than for second generation drugs.

Abstract
BACKGROUND Parental empowerment is known to increase parents' resources and to reduce stress, and therefore to improve family well-being. Professionals working in family services (child health clinics, school health care, day care, preschool and primary school) encounter families in various everyday settings and can significantly support parental empowerment. AIM This study aimed (i) to identify associations between parental empowerment and demographic and family service characteristics (i.e. parents' participation and perceived influence, decision-making and access to information) and (ii) to identify predictors of maternal and paternal empowerment. METHOD Study design was cross-sectional. Participants were mothers (n = 571) and fathers (n = 384) of children aged 0-9 who were selected by stratified random sampling in 2009. Associations were analysed by t-test, one-way analysis of variance and multiple linear regression analysis. RESULTS Sufficient perceived influence and joint decision-making by family and professionals on family service appointments emerged as significant variables of increased parental empowerment. Access to adequate information about municipal services was also associated with high empowerment. These family service characteristics were associated with parents' sense that they were able to manage in everyday life and had influence on specific service situations and family services in general. Mothers with a child aged under 3 or a child in home care or primary school, and fathers with a lower education feel less empowered in family services than other parents. CONCLUSION Knowledge about the factors associated with parental empowerment can contribute to further reinforce parental empowerment, help identify parents who need special attention and contribute to the development of family services.

Abstract
This pilot study sought to identify motivators and barriers to participating in a longitudinal survey; we interviewed patients and practitioners at a multidisciplinary primary care clinic where the proposed project would be based. While altruism motivates participation in medical research, we found that for many potential participants, the opportunity to benefit directly was the primary, and sometimes the only motive to participate or encourage participation in the research project. Patients often wanted direct feedback from their individual results, and they expected to provide consent before the results were forwarded to other parties such as their practitioners. Similarly, some practitioners were more likely to support the project if participation benefited patients directly. Other factors were also identified that influenced the acceptability and perceived risks and benefits of participating. More work is needed to understand these motivators and how patients might benefit directly from participating in health services research, especially when direct medical benefit is not possible.

Abstract
Accurate information concerning alcohol consumption level and patterns is vital to formulating public health policy. The objective of this paper is to critically assess the extent to which survey design, response rate and alcohol consumption coverage obtained in random digit dialling, telephone-based surveys impact on conclusions about alcohol consumption and its patterns in the general population. Our analysis will be based on the Canadian Alcohol and Drug Use Monitoring Survey (CADUMS) 2008, a national survey intended to be representative of the general population. The conclusions of this paper are as follows: (1) ignoring people who are homeless, institutionalized and/or do not have a home phone may lead to an underestimation of the prevalence of alcohol consumption and related problems; (2) weighting of observations to population demographics may lead to a increase in the design effect, does not necessarily address the underlying selection bias, and may lead to overly influential observations; and (3) the accurate characterization of alcohol consumption patterns obtained by triangulating the data with the adult per capita consumption estimate is essential for comparative analyses and intervention planning especially when the alcohol coverage rate is low like in the CADUMS with 34%.

Abstract
Background There is little empirical evidence regarding the generalisability of relative risk estimates from studies which have relatively low response rates or are of limited representativeness. The aim of this study was to investigate variation in exposure-outcome relationships in studies of the same population with different response rates and designs by comparing estimates from the 45 and Up Study, a population-based cohort study (self-administered postal questionnaire, response rate 18%), and the New South Wales Population Health Survey (PHS) (computer-assisted telephone interview, response rate ~60%). Methods Logistic regression analysis of questionnaire data from 45 and Up Study participants (n = 101,812) and 2006/2007 PHS participants (n = 14,796) was used to calculate prevalence estimates and odds ratios (ORs) for comparable variables, adjusting for age, sex and remoteness. ORs were compared using Wald tests modelling each study separately, with and without sampling weights. Results Prevalence of some outcomes (smoking, private health insurance, diabetes, hypertension, asthma) varied between the two studies. For highly comparable questionnaire items, exposure-outcome relationship patterns were almost identical between the studies and ORs for eight of the ten relationships examined did not differ significantly. For questionnaire items that were only moderately comparable, the nature of the observed relationships did not differ materially between the two studies, although many ORs differed significantly. Conclusions These findings show that for a broad range of risk factors, two studies of the same population with varying response rate, sampling frame and mode of questionnaire administration yielded consistent estimates of exposure-outcome relationships. However, ORs varied between the studies where they did not use identical questionnaire items.

Abstract
OBJECTIVE To estimate the prevalence of depression among people with diabetes and to examine the association of comorbid depression with lost productivity and health resource utilization in persons with and without diabetes. METHODS Cross-sectional survey, enrolling 12,643 individuals aged >18 years. Clustered, stratified sampling procedure was utilized. This sample represented 0.16% of the Hungarian adult population according to age, gender, and geographic regions. The severity of depressive symptoms was measured by the abbreviated Beck Depression Inventory. RESULTS The prevalence of diabetes in the sample was 6.2% (95% Confidence Interval (CI) = 5.7-6.6), and 13.4% (95% CI = 12.8-13.9) were classified as depressed. Adults with diabetes were two times more likely to have depression (adjusted odds ratio (OR) = 1.83, 95% CI = 1.53-2.19, p < .001) versus individuals without diabetes. Compared with nondepressed people with diabetes, those with diabetes and comorbid depression were older, less educated, more likely to be female and physically inactive, less likely to be employed, and married and had more comorbidities. In multivariate regression analyses, people with diabetes and depression had significantly greater odds of prolonged bed days due to illness (>or=20 days) (OR = 2.6, 95% CI = 1.69-3.88, p < .001), prolonged length of hospital stay (>or=18 days) (OR = 2.1, 95% CI = 1.27-3.45, p = .004), and multiple hospital admissions (>or=2) (OR = 1.8, 95% CI = 1.13-2.82, p = .01) compared with nondepressed diabetic patients. CONCLUSIONS These findings further document the association between depression and health resource utilization and lost productivity in people with diabetes. Screening and treating depression are important for everyday clinical care and public health initiatives to improve health outcomes for people with diabetes.

Abstract
OBJECTIVE To assess participation bias in the assembly of a specimen repository for genetic studies and to examine the association of participation with outcome within the Olmsted County myocardial infarction (MI) cohort. PARTICIPANTS AND METHODS From January 1, 1979, to May 31, 2006, 3081 persons had MI in Olmsted County, MN. Face-to-face contact was used to recruit patients who were hospitalized for an acute event. Persons who had had an MI before establishment of this repository were contacted by mail. At initial contact, we sought consent to use blood samples for genetic studies. Persons who refused were contacted by mail and were asked to consent to the use of stored tissue samples. For deceased subjects, stored tissue was collected when available. RESULTS Of the 3081 persons in the Olmsted County MI cohort, 1994 participated in the study; 1007 (50.5%) blood and 987 (49.5%) tissue specimens were provided. Participants were more likely to be younger men with hypertension, comorbidities, and non-ST-segment elevation MI (all, P<.05). Participants who provided blood specimens were more likely to have non-ST-segment elevation MI and lower Killip class than those who provided tissue. After adjustment for age, sex, hypertension, ST-segment elevation, Killip class, and comorbidities, participation was not associated with outcome. Participants who provided blood specimens were less likely to have heart failure (hazard ratio, 0.49; 95% confidence interval, 0.40-0.59; P<.01) or to die (hazard ratio, 0.16; 95% confidence interval, 0.12-0.21; P<.01) than those who provided tissue. CONCLUSION A variety of sources can be used to assemble community specimen repositories. Baseline characteristics differed between participants and nonparticipants and, among participants, by specimen source. Participants who provided blood specimens had better outcomes than those who provided tissue specimens. No survival advantage was observed for participants after combining blood and tissue specimens.

Abstract
Background The Florey Adelaide Male Ageing Study (FAMAS) examines the reproductive, physical and psychological health, and health service utilisation of the ageing male in Australia. We describe the rationale for the study, the methods used participant response rates, representativeness and attrition to date. Methods FAMAS is a longitudinal study involving approximately 1200 randomly selected men, aged 35–80 years and living in the north – west regions of Adelaide. Respondents were excluded at screening if they were considered incapable of participating because of immobility, language, or an inability to undertake the study procedures. Following a telephone call to randomly selected households, eligible participants were invited to attend a baseline clinic measuring a variety of biomedical and socio-demographic factors. Beginning in 2002, these clinics are scheduled to reoccur every five years. Follow-up questionnaires are completed annually. Participants are also invited to participate in sub-studies with selected collaborators. Results Of those eligible to participate, 45.1% ultimately attended a clinic. Non-responders were more likely to live alone, be current smokers, have a higheevalence of self-reported diabetes and stroke, and lower levels of hypercholesterolemia. Comparisons with the Census 2001 data showed that participants matched the population for most key demographics, although younger groups and never married men were under-represented and elderly participants were over-represented. To date, there has been an annual loss to follow-up of just over 1%. Conclusion FAMAS allows a detailed investigation into the effects of bio-psychosocial and behavioural factors on the health and ageing of a largely representative group of Australian men.

Abstract
We describe the design and the response indicators in a cross sectional study to estimate several factors associated with cardiovascular risk in the population of Castile and Leon. A sample of 4,950 individuals aged 15 years and above was obtained in two stages: in the first stage, 198 primary care physicians were selected and in the second stage a sample of 25 persons from each primary care physician's list was obtained. The response rate was 98% among primary care physicians and 80% among the population. Statistically significant differences were found in age distribution between the frame sample and the definitive sample. After applying design adjustments, only the group aged 35-64 years was significantly overdimensioned. Access to the general population in primary health care is a feasible and effective procedure. A high response rate contributes to the validity of the information.

Abstract
Sample surveys are used to investigate occurrence and determinants of diseases in populations. Their reliability is influenced by quality of sampling frame and response rate. We investigated relationship between sampling frame type and response rates and assessed their impact on non-response bias, using data from the WHO MONICA Project, where 37 centres in 20 countries conducted sample surveys, employing the best locally available sampling frame. Sampling frames fell into three categories: Population registers (PR), electoral registers (ER), and health care registers (HR). Response rate (rrs) was factored into components reflecting quality of sampling frame (contact rate cr) and characterizing willingness of sample members to participate (enrolment rate er). The mean quality score for the sampling frames was 92% for PR, 87% for HR and 85% for ER; they contributed on average 23, 20, and 26% to the respective non-response rates. For all frame types and both sexes the lowest quality score occurred in the age group 35 - 44, suggesting a reduced ability to track migration of a highly mobile population group. The patterns in the age/sex distribution of er indicate at least for males in PR and females in HR a potential for non-response bias. Estimation of non-response bias through an abbreviated questionnaire failed because of low item response. We found that contact rate characterizes sampling frame quality. For all frame types it had a major influence on response rate. It is likely that low er and low cr cause different kind of bias, requiring different measures to minimize their effects.

Abstract
STUDY OBJECTIVE To study the effect of using a mail questionnaire or home interviews on the size and the selectivity of response to national health surveys. DESIGN The interview survey and the mail survey were both carried out in the same country (the Netherlands) using the same sample frame, the same study period (1998) and collected partly the same data on demographic, socioeconomic and health characteristics. SETTING The Netherlands. PARTICIPANTS Dutch non-institutionalised inhabitants aged 25 years and over. MAIN RESULTS Response to the mail survey was lower (46.9%, n=3664) than to the interview survey (58.5%, n=6061). The mail survey gave higher response rates for women and lower response rates for persons with lower levels of education. Respondents to the mail survey reported lower rates of smoking but a slightly worse health status and higher figures on the use of health care services. No differences by method of data collection were found for age, marital status, region, household composition, work status and categories of body mass index. CONCLUSION Although the response of the mail survey was lower than the home interview survey, respondents showed generally small differences, with exception of level of education.

Abstract
The Women's Health Australia (WHA) project is a longitudinal study of several cohorts of Australian women, which aims to examine the relationships between biological, psychological, social and lifestyle factors and women's physical health, emotional well-being, and their use of and satisfaction with health care. Using the Medicare database as a sampling frame (with oversampling of women from rural and remote areas), 106,000 women in the three age groups 18-23, 45-50 and 70-75 were sent an invitation to participate and a 24-page self-complete questionnaire. Reminder letters, a nation-wide publicity campaign, information brochures, a freecall number for inquiries, and the option of completing the questionnaire by telephone in English or in the respondent's own language, were used to encourage participation. Statutory regulations precluded telephone follow-up of non-respondents. Response rates were 41% (N = 14,792), 54% (N = 14,200) and 36% (N = 12,614) for the three age groups. Comparison with Australian census data indicated that the samples are reasonably representative of Australian women in these age groups, except for a somewhat higher representation of women who are married or in a defacto relationship, and of women with post-school education. The most common reason for non-participation was lack of interest or time. Personal circumstances, objections to the questionnaire or specific items in it, and concerns about confidentiality were the other main reasons. Recruitment of three representative age-group cohorts of women, and the maintenance of these cohorts over a number of years, will provide a valuable opportunity to examine associations over time between aspects of women's lives and their physical and emotional health and well-being.
