Affective judgments, environmental determinants, and physical activity in emerging and young adults.

OBJECTIVE: Affective judgements represent a promising target for promoting physical activity among adults. This study examined whether relations between affective judgments and physical activity are robust after adjusting for social, built, and natural environmental determinants. DESIGN: Prospective cross-sectional study with 173 adults (70.1% female) aged 18-29 years who self-reported less than 90 minutes of moderate-to-vigorous physical activity. MAIN OUTCOME MEASURE: Physical activity volume (total daily step count, total activity counts) and durations of intensity-specific physical activity (light-intensity activity and moderate-to-vigorous intensity) were assessed for a seven-day period via waist-worn ActiGraph wGT3X-BT accelerometer. RESULTS: Affective judgements were not statistically associated with measures of physical activity volume or intensity-specific physical activity after adjusting for environmental influences. Support for exercise from friends was positively associated with measures of physical activity volume and moderate-to-vigorous physical activity duration. More favorable perceptions of the built environment were positively associated with moderate-to-vigorous intensity physical activity and negatively associated with duration of light-intensity physical activity. Longer photoperiods were associated with more light-intensity physical activity. CONCLUSION: Physical activity interventions for young and emerging adults reporting inactivity should target environmental determinants first and possibly wait until participants have a motivational stake in physical activity before targeting affective judgments.

Seasons, weather, and device-measured movement behaviors: a scoping review from 2006 to 2020.

BACKGROUND: This scoping review summarized research on (a) seasonal differences in physical activity and sedentary behavior, and (b) specific weather indices associated with those behaviors. METHODS: PubMed, CINAHL, and SPORTDiscus were searched to identify relevant studies. After identifying and screening 1459 articles, data were extracted from 110 articles with 118,189 participants from 30 countries (almost exclusively high-income countries) on five continents. RESULTS: Both physical activity volume and moderate-to-vigorous physical activity (MVPA) were greater in summer than winter. Sedentary behavior was greater in winter than either spring or summer, and insufficient evidence existed to draw conclusions about seasonal differences in light physical activity. Physical activity volume and MVPA duration were positively associated with both the photoperiod and temperature, and negatively associated with precipitation. Sedentary behavior was negatively associated with photoperiod and positively associated with precipitation. Insufficient evidence existed to draw conclusions about light physical activity and specific weather indices. Many weather indices have been neglected in this literature (e.g., air quality, barometric pressure, cloud coverage, humidity, snow, visibility, windchill). CONCLUSIONS: The natural environment can influence health by facilitating or inhibiting physical activity. Behavioral interventions should be sensitive to potential weather impacts. Extreme weather conditions brought about by climate change may compromise health-enhancing physical activity in the short term and, over longer periods of time, stimulate human migration in search of more suitable environmental niches.

Differences Between Mothers' and Fathers' Perception of Their Adolescents' Pain Before and After Parent Training Through The Comfort Ability Pain Management Program.

OBJECTIVE: To evaluate differences in how mothers and fathers perceive and respond to their adolescents' chronic pain before and after The Comfort Ability Program (CAP), a 1-day cognitive-behavioral intervention, and to compare outcomes between mother-father dyads and mothers who attended the intervention alone. METHODS: Parents completed the Pain Catastrophizing Scale (PCS) and Helping for Health Inventory (HHI) at baseline (preintervention) and at 1 week, 1 month, and 3 months after intervention. Confirmatory factor analyses evaluated construct validity and invariances of the scales. Paired t tests compared scores between mothers and fathers. Unpaired t tests compared mother-father dyads (n = 33) and mothers who attended the intervention alone (n = 73). RESULTS: PCS baseline showed significant construct instability between maternal and paternal interpretations. However, 1 week after intervention, construct stability improved between parents. On the PCS and HHI, in which lower scores represent more adaptive parenting behaviors, fathers scored significantly lower than mothers at baseline (PCS: 22.6 [7.7] vs 28.0 [11.4], p value = 0.033; HHI: 16.0 [8.1] vs 20.6 [9.6], p value = 0.029). At 3 months after intervention, PCS scores for both mothers and fathers significantly decreased from baseline (mothers: p value = 0.009; fathers: p value = 0.052) and converged (mothers: 18.6 [11.2] vs fathers: 18.3 [13.2]; p value = 0.786). Mother and father HHI scores were significantly lower at 3 months than baseline (mothers: 13.2 [9.5], p value = 0.005; fathers: 15.0 [12.7], p value = 0.017), although improvement of construct stability between parents was less evident. CONCLUSION: Findings suggest that mothers and fathers may differentially perceive and respond to their adolescents' pain and that CAP parent-training intervention may help align their thinking. The results further demonstrate that both parents make adaptive changes after intervention, reinforcing the value of including both parents in pediatric treatment for chronic pain.

Components of executive function model regional prefrontal volumes.

OBJECTIVE: Designed to measure a diversity of executive functioning (EF) through classical neuropsychological tests, the Delis-Kaplan Executive Function Scale (D-KEFS) allows for the investigation of the neural architecture of EF. We examined how the D-KEFS Tower, Verbal Fluency, Design Fluency, Color-Word Interference, and Trail Making Test tasks related to frontal lobe volumes, quantifying the regional specificity of EF components. METHOD: Adults from the Nathan Kline Institute-Rockland Sample (NKI-RS), an open-access community study of brain development, with complete MRI (3T scanner) and D-KEFS data were selected for analysis (N = 478; ages 20-85). In a mixed-effects model predicting volume, D-KEFS task, D-KEFS score, region of interest (ROI; 13 frontal, 1 occipital control), were entered as fixed effects with intercepts for participants as random effects. RESULTS: "Unitary" EF (aggregate of D-KEFS scores) was positively associated with superior frontal, rostral middle frontal, and lateral orbitofrontal volumes; a negative association was observed with frontal pole volume (| z-score slope | range = 0.040 to 0.051). "Diverse" EF skills (individual D-KEFS task scores) were differentially associated with two or three ROIs, respectively, but to a stronger extent (| z-score slope | range = 0.053 to 0.103). CONCLUSIONS: The neural correlates found for the D-KEFS support the prefrontal modularity of both unitary (aspects of EF ability common to all tasks) and diverse EF. Our findings contribute to emerging evidence that aggregate measurements of EF may serve broader but less robust frontal neural correlates than distinct EF skills.
