The Relationship

Purpose: The authors examined the relationship between mother and child activity. Methods: The authors compared moderate–vigorous physical activity (MVPA) and sedentary time of low-income mothers with obesity and their 6- to 12-year-old children on week (WD) and weekend (WE) days. A total of 196 mother–child pairs wore accelerometers simultaneously for a week. Mothers completed questionnaires. Spearman correlation and multivariate regression were used. Results: WE MVPA (accelerometry) was significantly correlated between mothers with children aged 6–7 (rs = .35) and daughters (rs = .27). Self-reported maternal PA time spent with one of their children was significantly correlated with the WE MVPA of all children (rs = .21) and children aged 8–10 (rs = .22) and with the WD MVPA of all children (rs = .15), children aged 8–10 (rs = .23), aged 11–12 (rs = .52), and daughters (rs = .37), and inversely correlated to the WD sedentary time of all children (rs = −.21), children aged 8–10 (rs = −.30), aged 11–12 (rs = −.34), daughters (rs = −.26), and sons (rs = −.22). In multivariate regression, significant associations were identified between reported child–mother PA time together and child MVPA and sedentary time (accelerometry). Conclusions: Mothers may influence the PA levels of their children with the strongest associations found in children aged 6–7 and daughters. Mother–child coparticipation in PA may lead to increased child MVPA and decreased sedentary behavior.

PURPOSE: This review aimed to evaluate the relationship between objectively measured physical activity and sedentary behavior and frailty in community-dwelling older adults.METHODS: An electronic search was undertaken using the MEDLINE® databases from January 1st 2010 to December 31st 2019. Titles, abstracts, and full texts of the studies identified by the search were scrutinized by the author to determine eligibility for an inclusion in this review.RESULTS: The search identified 87 relevant articles resulted, of which eight studies from four cohorts met the inclusion requirements. Almost all the studies reported a significantly negative association between moderate-to-vigorous physical activity (MVPA) and frailty, while only one was a longitudinal study. Significant associations between sedentary time (ST) and higher severity of frailty were observed, however, the findings of associations of sedentary bouts were mixed.IMPLICATION: Higher amounts of ST and lower amounts of MVPA were associated with a higher prevalence of frailty or worse frailty levels. Replacing ST with MVPA may offset the detrimental consequences of ST on frailty. More longitudinal studies and quantitative researches are needed to investigate the association of MVPA and ST bouts with frailty.

Background: Latinas have high rates of sedentary behavior and related health disparities, but it is unknown if interventions to increase physical activity will also reduce sedentary time. The current study examined changes in objectively measured sedentary time among Latinas in a randomized controlled trial of a physical activity intervention. Methods: Spanish-speaking Latinas (N = 202) were randomized to an exercise or wellness group and wore an accelerometer at baseline, 6 months, and 12 months. Results: Participants were sedentary on an average of 8.86 hours per day (SD = 2.60) at baseline. The intervention group had significantly greater increases in sedentary time compared with the control group, with the intervention group engaging in 146 more minutes per week of sedentary time at 6 months and 254 minutes per week of sedentary time at 12 months than the control group (P = .02). The intervention effect on sedentary behavior remained after controlling for moderate to vigorous physical activity. Additionally, time spent in moderate to vigorous physical activity was positively associated with more sedentary time (P = .04). Conclusion: An intervention to increase moderate to vigorous physical activity resulted in greater sedentary time, raising concerns regarding compensation and highlighting the need for interventions to address both physical activity and sedentary behavior to improve public health.

The Relationship

Abstract Background: Prior research examining the relationship between cannabis use, sedentary behavior, and physical activity has generated conflicting findings, potentially due to biases in the self-reported measures used to assess physical activity. This study aimed to more precisely explore the relationship between cannabis use and sedentary behavior/physical activity using objective measures. Methods: Data were obtained from the 2005-2006 National Health and Nutrition Examination Survey. 2,092 participants (ages 20-59; 48.8% female) had accelerometer-measured sedentary behavior, light physical activity, and moderate-to-vigorous physical activity. Participants were classified as a current cannabis user if they reported any use over the previous 30 days. Multivariable linear regression estimated minutes engaged in sedentary behavior/physical activity for current versus non-current cannabis users. Logistic regression modeled self-reported moderate-to-vigorous physical activity in relation to current cannabis use. Results: Fully-adjusted regression models indicated that current cannabis users’ objectively-measured sedentary behavior/physical activity did not significantly differ from non-current users. There were no significant associations between self-reported moderate-to-vigorous physical activity and cannabis use. Conclusions: This study is the first to evaluate the relationship between cannabis use and accelerometer-measured sedentary behavior and physical activity. Such objective measures should be used in other cohorts to replicate our finding that current cannabis use is not significantly associated with sedentary behavior/physical activity in order to fully assess the potential public health impact of recent increases in cannabis use.

A total of 2,092 participants (ages 20–59; 48.8% female) had accelerometer-measured sedentary behavior, light physical activity, and moderate-to-vigorous physical activity. Participants were classified as light, moderate, frequent, or non-current cannabis users depending on how often they used cannabis in the previous 30 days. Multivariable linear regression estimated minutes in sedentary behavior/physical activity by cannabis use status. Logistic regression modeled self-reported moderate-to-vigorous physical activity in relation to current cannabis use. Results Fully adjusted regression models indicated that current cannabis users’ accelerometer-measured sedentary behavior did not significantly differ from non-current users. Frequent cannabis users engaged in more physical activity than non-current users. Light cannabis users had greater odds of self-reporting physical activity compared to non-current users. Conclusions This study is the first to evaluate the relationship between cannabis use and accelerometer-measured sedentary behavior and physical activity. Such objective measures should be used in other cohorts to replicate our findings that cannabis use is associated with greater physical activity and not associated with sedentary behavior in order to fully assess the potential public health impact of increases in cannabis use.

Abstract This study investigated the role of objectively measured moderate–vigorous physical activity (MVPA) and sedentary behavior on cardiometabolic risk factors of young Latino children. We hypothesized that MVPA would be associated with lower cardiometabolic risk when sedentary behavior is low. We studied 86 primarily low-income, Latino children using a cross-sectional study design. The study sample consisted of 51 girls and 35 boys, with mean age 5.6 (SD = .53) years. Physical activity was measured by accelerometry, anthropometric measures obtained, and fasting blood samples were used to measure cardiometabolic risk factors. Greater levels of sedentary behavior were associated with increased waist circumference (rs = .24, p < .05) and metabolic risks. MVPA, however, had significant beneficial associations with all cardiometabolic risk factors (rs-range = −.20 to −.45, p < .05) with the exception of plasma insulin. MVPA predicted latent variables representing anthropometric risk (β = −.57, p < .01), cardiac risk (β = −.74, p < .01), and metabolic risk (β = −.88, p < .01). Sedentary behavior significantly moderated the effect of MVPA on anthropometric (β-interaction = .49, p < .01), cardiac (β-interaction = .45, p < .01), and metabolic risk (β-interaction = .77, p < .01), such that more MVPA was associated with better health outcomes under conditions of lower sedentary behavior. The model explained 13%, 22%, and 45% variance in anthropometric, cardiac, and metabolic risk factors, respectively. Increased MVPA is associated with decreased cardiometabolic risk in young Latino children, particularly when sedentary behavior is low.

Background. Regular physical activity in childhood and adolescent plays an important role in reducing the risk of cardiovascular health diseases, diabetes, and obesity in adulthood. However, little is known about physical activity levels (PA) and sedentary time among children and adolescents in Morocco. Objective. To examine gender, type of day, and age grade differences in objectively measured sedentary time, physical activity levels, and physical activity guideline attainment among children and adolescents in Morocco. Method. 172 children/adolescents (mean age = 10.92 ± 1.55 years, 49.4% are boys) were recruited for this study and wore a tri-axial accelerometer (GT3X+) for 7 consecutive days. Time spent in sedentary, PA levels, and daily steps were measured and compared according to gender, age grade, and the type of day (weekdays/weekends). Results. In weekdays children/adolescents spent more time in sedentary than weekends (p < 0.001). Boys were eight times more likely to meet the recommendation for at least 60 min of moderate to vigorous physical activity per day than girls (OR: 8.569; 95% [CI]: 4.23–17.32), p < 0.001. Conclusion. These findings highlight the need for effective and sustainable strategies and programs aiming to promote physical activity and to reduce sedentary behavior among children and adolescents in Morocco.

Abstract Background: In this manuscript, we aimed at investigating whether objectively measured lifestyle factors, including walking steps, sedentary time, amount of unforced physical activity, level of slight and energetic physical activity, conversation time, and sleep parameters altered before and during the COVID-19 pandemic among community-dwelling older adults.Methods: Data were obtained from a prospective cohort study conducted from 2015 to 2019 and a subsequent dementia prevention study undertaken in September 2020. Community-dwelling adults aged ≥65 years wore wearable sensors before and during the pandemic.Results: A total of 56 adults were enrolled in this study. The mean age was 74.2±3.9 years, and 58.9% (n=33) of the participants were female. The moderate and vigorous physical activity time significantly decreased and sedentary time significantly increased during the pandemic. Conclusions: This is the first study to demonstrate differences in objectively assessed lifestyle factors before and during the COVID-19 pandemic among community-dwelling older adults. The findings show that the pandemic has adversely affected physical activity among older adults living on their own in Japan.

Increased skeletal muscle fat infiltration (i.e. myosteatosis) is now recognized as a major risk factor for cardio-metabolic diseases. Therefore, a lifestyle modification that reduces myosteatosis would be of great public health importance. However, studies examining the association of relevant lifestyle factors with this ectopic fat depot are lacking, particularly in African ancestry populations who have a very high burden of cardio-metabolic diseases. The aim of this study was to examine the relation between objectively measured physical activity and sedentary behavior with computed tomography measured calf muscle attenuation among middle-aged and elderly African-Caribbeans from the population-based Tobago Health Study. Preliminary analyses were conducted among 134 women (mean age 59 yrs, mean BMI 31.6 kg/m 2 ) and 355 men (mean age 62 yrs, mean BMI 28 kg/m 2 ). Physical activity was measured using the SenseWear Pro armband worn for 4-7 days. We calculated the mean duration of waking time engaged in light physical activity (LPA), moderate to vigorous activity (MVPA), and sedentary behavior (SB) per day. Skeletal muscle attenuation (mg/cm 3 ) reflects the fat content of the muscle such that greater skeletal muscle fat infiltration is reflected by lower attenuation. Women spent less time in LPA (146 vs. 270 min/day) and MVPA (15 vs. 41 min/day), but more time in SB (789 vs. 647 min/day) than men (all p<0.0001) after adjustments for gender differences in age. Muscle attenuation was lower among women compared with men (70.5 vs. 72.7 mg/cm3; age and BMI adjusted p<0.0001). In both women and men, muscle attenuation was positively correlated with the LPA and MVPA, and inversely with time spent in SB (spearman correlation coefficients (r) ranged from 0.21 to 0.39, all p<0.006 adjusted for age). Upon additional adjustment for BMI, in both women and men, the association of muscle attenuation with MVPA remained significant (r=0.21 and r=0.18, respectively, both p<0.03), but there was no association with LPA. Percent time spent in SB was associated with muscle attenuation only among women after additional adjustment for BMI (women: -0.16, p=0.052), and we also found a significant sex interaction effect of SB on muscle attenuation (p=0.035). Our preliminary findings suggest that there is significant association between MVPA and myosteatosis among middle-aged and elderly African Caribbeans. However, SB may only be relevant for myosteatosis among women. Future analyses will be conducted in a larger sample from this cohort to confirm our findings and to test for independence from other potential confounding factors, such as diet, sleep patterns, adiposity distribution, and diabetes.
