BACKGROUND Commercial off-the-shelf activity trackers (e.g., Fitbit) allow users to self-monitor their daily activity, including number of steps, type of PA, and amount of sleep, among other features. Fitbits have been used as both measurement and intervention tools. However, it is not clear how they are being incorporated into PA intervention studies, and differences in use protocols across the life course (e.g., models, strategies to boost wear time) are not known. OBJECTIVE This paper aimed to review the use of Fitbit devices in PA intervention research across the life course in order to provide intervention scientists with a synthesis of information that may inform their future trials involving Fitbit devices. METHODS We conducted a search of the Fitabase Fitbit Research Library. Of the 682 studies available on the Fitabase Fitbit Research Library, 79 interventions met the eligibility criteria for this review and 44 were selected for inclusion, representing interventions conducted in childhood, adolescence, early, middle, and older adulthood. RESULTS Most studies used developmentally appropriate behavior change techniques and wear time instructions. Device wear instructions differed substantially across studies, ranging from a specific number of hours over a given assessment period to daily wear for the duration of the intervention. Strategies to boost wear time included daily reminders through texts and syncing Fitbit data. Minimum wear time criteria differed considerably, both within and between developmental stages. Additionally, rates of adherence to wear time criteria were reported using varying metrics. Most studies supplemented the use of Fitbits with additional objective or self-report measures for PA. CONCLUSIONS Future work should focus on developing standardized protocols for using commercially available devices, especially the most popular ones, in the context of research.

The Life Course

The victim–offender overlap is currently under discussion in criminology. However, the connection between victimization and offending over the life course still requires further investigation. The present study examines whether the victim–offender overlap is invariant during the transition from adolescence to early adulthood using seven consecutive waves of the German Research Foundation–funded self-report study “Crime in the Modern City,” which contain information about German students from the age of 14 to 20 years. The results indicate that the nature as well as the strength of the overlap changes over the period from adolescence to early adulthood. The introduced measurement of the relative victim–offender overlap indicates that with growing up, fewer victims are also offenders whereas the amount of offenders that are also victims remains stable. Longitudinal analyses based on latent growth and cross-lagged panel models further point out that the developments of victimization and offending are highly parallel processes that evince similar stability and mutual influence over the phase of youth and adolescence. However, the association between both weakens over age. In conclusion, our results suggest variance in the victim–offender overlap over the life course. This justifies the demand for further research and theory development on this criminological phenomenon.

Research And Policy

The idea that early-life circumstances shape people’s health, development, and well-being over the life course has gained renewed centrality in the last two decades. This renewed interest has been informed by new approaches that emphasize sensitive and critical periods during the first years of life, offer an understanding of human development as a hierarchical and cross-fertilizing process, suggest plausible mechanisms for the persistent effect of early exposures, and explore heterogeneity in effects based on environmental and biological factors. The articles included in this special issue of Population Research and Policy Review advance the field of early-life circumstances in several important dimensions. They examine the determinants and effects of noxious exposures at different developmental stages—ranging from the prenatal period to adolescence—in a variety of national settings. They offer an understanding of early-life circumstances that moves from discrete outcomes to a dynamic life-course approach, and consider diverse sources of heterogeneity in the effects of early exposures.

Purpose – The purpose of this paper is to explore the factors that impact on the well-being of women workers, as assessed through depression, anxiety and stress, across the life course, i.e. age, marital status and parental status. Design/methodology/approach – The quantitative study was cross-sectional in nature and used an online self-report questionnaire to generate information on job/work characteristics, belief systems and demographic variables. A snowball sample was used to recruit the respondents. Findings – The results showed that the availability of resources was the influencing factor in women workers maintaining their well-being. Those respondents with resources, such as job autonomy and support from colleagues, were less likely to be depressed, anxious or stressed. The life course was not an influencing factor in the models tested suggesting that regardless of women's stage in life, they require appropriate resources to address the demands of the work environment, to maintain their well-being. Practical implications – The implications of this study are that when considering diversity in the work environment, it is important to assess if all workers have the resources they require to cope with the demands of the workplace. Originality/value – This present study outlines the importance of the life course in the context of the workplace, but highlights also that it is only one perspective and that others should be considered; such as those factors that are inherent in improving well-being and relationships within organisations.

We examined the association between life course body weight percentile trajectories and risk for preterm delivery (PTD). Data about women’s weight at birth, age 18, and before pregnancy were obtained by retrospective self-report in a cohort of 1410 black women in metropolitan Detroit. Growth mixture models were used to categorize women with similar weight percentile trajectories across these time points. Log-Poisson models were used to examine the association between the trajectory groups and PTD. Four trajectory groups with different beginning and endpoints of their weight percentiles (high-high, high-low, low-high and low-low) best fit the data. The groups with the highest prevalence of PTD were those that started low (low-high, 21%; low-low, 18%). The low-high group had a higher prevalence of PTD than the high-high trajectory group in unadjusted models (prevalence ratio=1.49 [95% confidence interval (CI) 1.11, 2.00]). The association became not significant after adjusting for maternal age at delivery, income, diabetes and hypertension. When compared with the high-high trajectory group, the low-low trajectory seemed to also have a higher prevalence of PTD after adjusting for maternal age at delivery, income, diabetes and hypertension (prevalence ratio=1.35 [95% CI 1.00, 1.83]). Results suggest that a woman’s risk for PTD is influenced by her body weight trajectory across the life course.

The Relationship

Socioeconomic position (SEP) is a key determinant of diet quality across the life course. Young adulthood is a unique period of transition where dietary inequities between groups with lower and higher SEP may widen. This study investigated associations between SEP in both childhood and young adulthood and diet quality in young adulthood. Data from 1949 Canadian young adults aged 18–30 who participated in the Canada Food Study were analyzed. Healthy Eating Index–2015 (HEI-2015) scores were calculated based on one 24-hour dietary recall. Childhood and young adult SEP were represented by self-report of participants’ parent(s)’ and their own highest educational level, respectively. Linear regression was used to examine associations between childhood and adult SEP and adult HEI-2015 score. Mediation analyses examined whether adult SEP mediated the relationship between childhood SEP and adult HEI-2015 score. Lower SEPs in childhood and adulthood were each associated with lower HEI-2015 scores in young adulthood. Adult SEP mediated up to 13.0% of the association between childhood SEP and adult HEI-2015 scores. Study findings provide support for key life course hypotheses and suggest latent, pathway, and cumulative effects of SEP across the early life course in shaping the socioeconomic patterning of diet quality in young adulthood.

BACKGROUND Exergaming is increasing in popularity, but little is known about sustained exergaming. OBJECTIVE The objectives of this study were to describe the frequency and correlates/predictors of sustained exergaming. METHODS Data were available in AdoQuest (2005-11), a longitudinal investigation of 1843 grade 5 students in in Montréal, Canada. This analysis uses data from grade 9 and 11. Participants at T1 (mean age 14 (0.8) years) who reported past-week exergaming (n = 186), completed mailed self-report questionnaires at T2 (mean age 16 (0.8) years). Independent correlates (from T2)/predictors (from T1 or earlier) were identified using multivariable logistic regression. RESULTS Of 186 exergamers at T1, 81 (44%) reported exergaming at T2. Being female and having higher introjected regulation (i.e., a type of PA motivation indicative of internalization of PA as a behaviour) were independent correlates.. None of the predictors investigated were associated with sustained exergaming. CONCLUSIONS Almost 50% of grade 9 exergamers sustained for 2-3 years. In non-clinical settings, exergaming may be a viable approach to help adolescents maintain PA during adolescence, a period in the life course when PA generally declines. Sex and PA motivation should be considered in the design of exergaming interventions. CLINICALTRIAL N\A

Building on previous research, this article investigates whether discrepancies between official and self-reported measures of arrests as an adult can be predicted from such discrepancies as an adolescent. We use longitudinal data from the Rochester Youth Development Study to assess whether a pattern exists in adolescent and adult under- and over-reporting of arrests. We find consistency in under- and over-reporting throughout the adolescent–young adult life course. In other words, when respondents misreport the number of arrests they have experienced, they do so consistently regardless of age. This is reassuring for scholars using self-report data, as under- and over-reporting behaviors remain stable over this span of the life course. Finally, our models predicting discrepancies in official and self-reported arrests during the combined period of adolescence and young adulthood are both extremely strong. Our findings support the continued use of self-report measures as a valid indicator of delinquency.
