IntroductionDespite the positive impact walking has on human health, few opportunities exist for workers with largely sedentary jobs to increase physical activity while at work. The objective of this pilot study was to examine the implementation, feasibility, and acceptability of using a Walking Meeting (WaM) protocol to increase the level of work-related physical activity among a group of sedentary white-collar workers.MethodsWhite-collar workers at a large university were invited to participate in a newly developed WaM protocol. Workers who conducted weekly meetings in groups of 2 or 3 individuals were recruited for the pilot study (n = 18) that took place from January 2015 to August 2015. Seventeen participants wore an accelerometer to measure physical activity levels during 3 consecutive weeks (first week baseline, followed by 2 weeks of organized WaMs) and participated in focus groups conducted during week 3 to document experiences with the WaM protocol.ResultsThe WaM protocol met study criteria on feasibility, implementation, and acceptability among study participants. The average number of minutes (standard deviation) participants engaged in combined work-related moderate/vigorous physical activity per week during the 3 weeks increased from an average of 107 (55) minutes during the baseline week to 114 (67) minutes at week 2 and to 117 (65) minutes at week 3.ConclusionWhite- collar workers were supportive of transforming regular seated meetings into walking meetings and increased their work-related physical activity levels.

IntroductionMany older adults are not physically active despite the well-documented health benefits of regular exercise. We examined cardiovascular, strength, and mobility outcomes among a sample of racially/ethnically diverse adults aged 55 or older participating in a community park-based physical activity program. MethodsWe assessed the following among adults aged 55 or older who attended a 1-hour park-based fitness class 2 or 3 times per week for 21 weeks: 1) 3 fitness outcomes, 2) systolic and diastolic blood pressure, 3) height and weight (to assess body mass index), and 4) pulse. We collected data at baseline (August-September 2016) and follow-up (January-February 2017). Linear regression analysis, adjusting for sex, age, and race/ethnicity, examined the association between program participation and changes in outcomes. ResultsAdjusted models showed a mean decrease in systolic blood pressure (−3.80 mm Hg; 95% CI, −6.75 to −0.84 mm Hg) and diastol-ic blood pressure (−1.54 mm Hg; 95% CI, −3.01 to −0.06 mm Hg) and a mean increase in number of arm curls completed in 30 seconds (1.66; 95% CI, 0.71-2.61) from baseline to follow-up among all participants. Hispanic participants, compared with non-Hispanic white and non-Hispanic black participants, showed greater improvements in mean body mass index (−2.48; 95% CI, −4.60 to −0.34), systolic blood pressure (8.59 mm Hg; 95% CI, −16.82 to −0.36 mm Hg), diastolic blood pressure (−7.06 mm Hg; 95% CI, −11.16 to −2.97 mm Hg), and pulse (−6.53 beats per minute; 95% CI, −11.38 to −1.67 beats per minute). ConclusionPark-based fitness classes tailored to older, racially/ethnically diverse adults can improve cardiovascular health and strength.

Background: Firefighters suffer from a disproportionally high burden of chronic diseases that could be prevented from regular bouts of physical activity (PA). The goal(s) of this pilot study were to (a) describe typical PA levels in professional paid firefighters, and (b) assess their ability to estimate their own levels of PA. Methods: A repeated measures study design was used to assess self-reported and objectively measured levels of PA from a non-probabilistic sample of firefighters ( n = 18) over 1 week. Objective measures of PA, measured by accelerometry were defined as the number of minutes spent in sedentary, light, moderate, and vigorous PA. Firefighters completed a follow-up questionnaire recording their self-reported levels of PA. Results: Obese (body mass index [BMI] > 30 kg/m2) firefighters spent 8,033 ± 2,543 minutes/week in sedentary activity, overweight (BMI = 25–29 kg/m2) firefighters 6,533 ± 1,587 minutes/week, and healthy weight (BMI = 18.5–24.9 kg/m2) firefighters 5,846 ± 1,160 minutes/week. The difference in self-reported weekly minutes spent in light, moderate, and vigorous activity and objectively measured minutes in activity was calculated. Healthy weight firefighters reported the least difference (1,924 minutes/week), followed by the overweight (3,884 minutes/week) and obese (5,749 minutes/week). Conclusion/Application to Practice: Firefighters poorly estimated their true level of PA compared with their objectively measured PA and obese firefighters reported the greatest inconsistency. Occupational health nurses should aim to support firefighters in achieving PA levels that assist firefighters to achieve a healthy weight and educate them about what it means to be engaged in each level of PA.

Background: Only 24% of US youth meet physical activity recommendations set by the Centers for Disease Control and Prevention. Research demonstrates that community-based programs provide underresourced minority youth with opportunities for routine physical activity, although limited work draws from accelerometry data. This study objectively assessed youth physical activity attributable to participation (vs nonparticipation) days in a park-based afterschool program in Miami-Dade County, Miami, FL. Methods: Participants’ (n = 66; 60% male; 57% white Hispanic, 25% non-Hispanic black, 14% Black Hispanic, mean age = 10.2 y) physical activity was assessed April to May 2019 over 10 days across 7 park sites using Fitbit (Charge 2) devices. Separate repeated-measures multilevel models were developed to assess the relationship between program daily attendance and total (1) moderate to vigorous physical activity minutes and (2) step counts per day. Results: Models adjusted for individual-level age, sex, race/ethnicity, poverty, and clustering by park showed significantly higher moderate to vigorous physical activity minutes (β = 25.33 more minutes per day; 95% confidence interval, 7.0 to 43.7, P < .01) and step counts (β = 4067.8 more steps per day; 95% confidence interval, 3171.8 to 4963.8, P < .001) on days when youth did versus did not attend the program. Conclusions: Study findings suggest that park-based programs may support underserved youth in achieving daily physical activity recommendations.
