Valid, reliable, and direct measures of physical activity (PA) are critical to assessing the impact of lifestyle PA interventions. However, little is known about the extent to which objective measures have been used to assess the outcomes of lifestyle PA interventions. This systematic review had two aims: 1) evaluate the extent to which PA is measured objectively in lifestyle PA interventions targeting adults and 2) explore and summarize what objective measures have been used and what PA dimensions and metrics have been reported. Pubmed, Cochrane Central Register, and PsychInfo were searched for lifestyle PA interventions conducted between 2006 and 2016. Of the 342 articles that met the inclusion criteria, 239 studies measured PA via subjective measures and 103 studies measured PA via objective measures. The proportion of studies using objective measures increased from 4.4% to 70.6% from 2006 to 2016. All studies measuring PA objectively utilized wearable devices; half (50.5%) used pedometers only and 40.8% used accelerometers only. A majority of the 103 studies reported steps (73.8%) as their PA metric. Incorporating objective measures of PA should continue to be a priority in PA research. More work is needed to address the challenges of comprehensive and consistent collecting, reporting, and analyzing of PA metrics.
Objective To evaluate racial/ethnic disparities among children and adolescents in meeting the 4 daily 5-2-1-0 nutrition and activity targets in a nationally representative sample. The 5-2-1-0 message summarizes 4 target daily behaviors for obesity prevention: consuming ≥5 servings of fruit and vegetables, engaging in ≤2 hours of screen time, engaging in ≥1 hour of physical activity, and consuming 0 sugar-sweetened beverages daily. Study design The National Health and Nutrition Examination Survey (2011–2012) data were used. The study sample included Hispanic (n = 608), non-Hispanic black (n = 609), Asian (n = 253), and non-Hispanic white (n = 484) youth 6–19 years old. The 5-2-1-0 targets were assessed using 24-hour dietary recalls, the Global Physical Activity Questionnaire, and sedentary behavior items. Outcomes included meeting all targets, no targets, and individual targets. Multivariable logistic regression models accounting for the complex sampling design were used to evaluate the association of race/ethnicity with each outcome among children and adolescents separately. Results None of the adolescents and <1% of children met all 4 of the 5-2-1-0 targets, and 19% and 33%, of children and adolescents, respectively, met zero targets. No racial/ethnic differences in meeting zero targets were observed among children. Hispanic (aOR, 1.76 [95% CI, 1.04–2.98]), non-Hispanic black (aOR, 1.82 [95% CI, 1.04–3.17]), and Asian (aOR, 1.48 [95% CI, 1.08–2.04]) adolescents had greater odds of meeting zero targets compared with non-Hispanic whites. Racial/ethnic differences in meeting individual targets were observed among children and adolescents. Conclusions Despite national initiatives, youth in the US are far from meeting 5-2-1-0 targets. Racial/ethnic disparities exist, particularly among adolescents.
Obesity remains a persistent public health and health disparity concern in the United States. Eliminating health disparities, particularly among racial/ethnic minority groups, is a major health priority in the US. The primary aim of this review was to evaluate representation of racial/ethnic sub-group members in behavioral weight loss interventions conducted among adults in the United States. The secondary aims were to assess recruitment and study design approaches to include racial/ethnic groups and the extent of racial/ethnic sub-group analyses conducted in these studies. PubMed, PsycInfo, Medline, and CINAHL were searched for behavioral weight loss intervention trials conducted in 2009–2015 using keywords: weight, loss, overweight, obese, intervention and trial. Most of the 94 studies included a majority of White participants compared to any other racial/ethnic group. Across the included studies, 58.9% of participants were White, 18.2% were African American, 8.7% were Hispanic/Latino, 5.0% were Asian and 1.0% were Native Americans. An additional 8.2% were categorized as “Other”. Nine of the 94 studies exclusively included minority samples. Lack of adequate representation of racial and ethnic minority populations in behavioral trials limits the generalizability and potential public health impact of these interventions to groups that might most benefit from weight loss. Given racial/ethnic disparities in obesity rates and the burden of obesity and obesity-related diseases among minority groups in the United States, greater inclusion in weight loss intervention studies is warranted.
Objectives To examine the association between sugar-sweetened beverage availability at home and sugar-sweetened beverage consumption, and to evaluate whether this association was consistent across school and school neighborhood sugar-sweetened beverage availability. Study design Secondary data analyses were performed from the 2014 cross-sectional, Internet-based Family Life, Activity, Sun, Health, and Eating (FLASHE) study of 1494 adolescents (age 12–17 years). Ordinal logistic regression analyses were conducted to examine the association between sugar-sweetened beverage availability in the home and adolescents’ frequency of sugar-sweetened beverage consumption (nondaily, <1; daily, 1-<2; daily, ≥2), adjusting for adolescent age, sex, race, and body mass index and parent marital status and housing insecurity. Stratified ordinal logistic regression analyses were used to examine the associations by school and school neighborhood sugar-sweetened beverage availability. Results One-third (32.6%) of adolescents were nondaily consumers of sugar-sweetened beverages, 33.9% consumed 1-<2 sugar-sweetened beverages daily, and 33.5% consumed ≥2 sugar-sweetened beverages daily. Almost one-half (44.4%) reported that sugar-sweetened beverages were often or always available in the home. Frequency of sugar-sweetened beverage availability at home was associated with greater sugar-sweetened beverage consumption (OR, 2.88; 95% CI, 2.86–2.89 for rarely/sometimes available at home; OR. 5.62; 95% CI, 5.60–5.64 for often/always available at home). Similar associations were found regardless of the availability of sugar-sweetened beverages in the adolescent’s school or school neighborhood. Conclusions Sugar-sweetened beverage availability in the home was associated with adolescent sugar-sweetened beverage consumption, regardless of sugar-sweetened beverage availability in other settings, and may be a key target for obesity prevention efforts.

Objective: To examine the relationships between spirituality and physical activity and sedentary behavior in a sample of Latino adults in Massachusetts.Design: This is a cross-sectional analysis of the Lawrence Health and Well Being Study; a study that was conducted among patients at the Greater Lawrence Family Health Center (GLFHC) in Lawrence, Massachusetts.Participants: 602 Latino or Hispanic adults aged 21 to 85 years completed the study. Results:There was a significant negative relationship between spirituality and sedentary behavior (β= -.12, p = .004). Although not statistically significant, higher spirituality was associated with increased odds of engaging in physical activity. There were no significant associations between spirituality and physical activity among men or women. Men with greater spirituality were significantly less sedentary (β = -.17, P = .005). There was no relationship between sedentary behavior and spirituality among women. Conclusions:This study found that individuals who are more spiritual are also less sedentary, and this association was stronger in men than women. Findings provide insight for developing future interventions to promote activity in this high-risk population, which has been greatly understudied. Future research endeavors should consider investigating the impact of spirituality-based messages to reduce sedentary behavior among Latinos.
