Examining the use of wearable activity monitors and goal setting toward a step goal
Soto Graycie , Omura John D , Fulton Janet E , Whitfield Geoffrey P . Med Sci Sports Exerc 2022 54 170-170 PURPOSE: Wearable activity monitors (wearables) are increasingly used in the US and can help encourage physical activity participation through step counts. Understanding whether wearable users track daily step counts and how they set step goals can help ensure wearables are designed and used to maximize their public health impact. This study examined the proportion of US adults who use wearables, and among users whether wearables are used to track daily step counts and how they determine their daily step count goals. | | METHODS: Data from a nationwide sample of US adults (SummerStyles, 2020) were analyzed (N = 3661). Participants were asked if they have ever used a wearable and were categorized as a current, past, or never user. Current users were asked if they use their wearable to track their daily step count. Those who responded yes were asked if they determine their daily step goal by using the default goal, a personal goal, no goal, or that they gradually increase their step goal. Prevalence of wearable users, use of wearable to track daily step counts, and how users determine daily step count goals were calculated overall and by demographic characteristics. Pairwise t tests were used to identify significant differences between subgroups (p < .05). | | RESULTS: Overall, 31.4% of US adults currently use a wearable activity monitor. Among current users (n = 1219), 88.3% reported using their device to track their daily step count with a greater prevalence among females (91.2%) compared to males (84.6%) and among Hispanics (95.2%) compared to Whites (87.1%). Current wearable users reported determining their step count goal by using the default goal (41.7%), their own personal goal (32.9%), not having a daily goal (17.4%), and gradually increasing their daily goal (8.0%). | | CONCLUSION: Nearly 9 in 10 wearable users track their daily step count on their devices. Most users set step goals based on default settings or personal goals, so establishing evidence-based steps per day guidelines may help wearable users achieve levels of health enhancing physical activity. |
Physical activity level of the military age- and BMI-eligible population of the United States, 2015-2020
Webber Bryant J , Omura John D , Bornstein Daniel B , Deuster Patricia A , O'Connor Francis G , Park Sohyun , Whitfield Geoffrey P . Med Sci Sports Exerc 2022 54 54-55 PURPOSE: Inadequate pre-enlistment physical activity is a risk factor for musculoskeletal injury during and discharge from basic military training. We estimated the prevalence of physical activity (PA) participation among the US population eligible to enter the armed forces based on age and body mass index (BMI) overall and by selected characteristics. | | METHODS: Data on non-pregnant, age-eligible respondents (aged 17-42 years) were analyzed from the January 2015 - March 2020 National Health and Nutrition Examination Survey (unweighted n = 5964). In accordance with Department of Defense policy, BMI eligibility was defined as 19.0-27.5 kg/m2; BMI was calculated from measured weight and height. Based on guidance from the US Army Pre-Basic Combat Training Physical Training Program and the Physical Activity Guidelines for Americans, 2nd edition, we characterized inadequate PA participation as < 300 minutes/week of equivalent moderate-intensity PA from all domains. We calculated PA overall and compared PA by gender, age, race/ethnicity, education, and family income using the Satterthwaite adjusted F-test. | | RESULTS: Of the age-eligible population, 47.3% were BMI eligible. Among those eligible by age and BMI, 27.5% had an inadequate PA level. Prevalence of inadequate PA was lower among males than females (P = .001) and non-Hispanic white persons versus other racial/ethnic groups (P < .001); no significant differences were evident by age, education, or family income. Among those with BMI < 19.0 kg/m2 and > 27.5 kg/m2, respective prevalence of inadequate PA was 36.3% and 36.5%. | | CONCLUSIONS: Less than half of the military age-eligible US population has an eligible BMI for entering the US armed forces. Over a quarter of these report PA that may be inadequate for basic military training. Promotion of healthy weight status and participation in PA in young adults could help improve readiness to enter the armed forces. |
Association of State-Issued Mask Mandates and Allowing On-Premises Restaurant Dining with County-Level COVID-19 Case and Death Growth Rates - United States, March 1-December 31, 2020.
Guy GPJr , Lee FC , Sunshine G , McCord R , Howard-Williams M , Kompaniyets L , Dunphy C , Gakh M , Weber R , Sauber-Schatz E , Omura JD , Massetti GM . MMWR Morb Mortal Wkly Rep 2021 70 (10) 350-354 CDC recommends a combination of evidence-based strategies to reduce transmission of SARS-CoV-2, the virus that causes COVID-19 (1). Because the virus is transmitted predominantly by inhaling respiratory droplets from infected persons, universal mask use can help reduce transmission (1). Starting in April, 39 states and the District of Columbia (DC) issued mask mandates in 2020. Reducing person-to-person interactions by avoiding nonessential shared spaces, such as restaurants, where interactions are typically unmasked and physical distancing (≥6 ft) is difficult to maintain, can also decrease transmission (2). In March and April 2020, 49 states and DC prohibited any on-premises dining at restaurants, but by mid-June, all states and DC had lifted these restrictions. To examine the association of state-issued mask mandates and allowing on-premises restaurant dining with COVID-19 cases and deaths during March 1-December 31, 2020, county-level data on mask mandates and restaurant reopenings were compared with county-level changes in COVID-19 case and death growth rates relative to the mandate implementation and reopening dates. Mask mandates were associated with decreases in daily COVID-19 case and death growth rates 1-20, 21-40, 41-60, 61-80, and 81-100 days after implementation. Allowing any on-premises dining at restaurants was associated with increases in daily COVID-19 case growth rates 41-60, 61-80, and 81-100 days after reopening, and increases in daily COVID-19 death growth rates 61-80 and 81-100 days after reopening. Implementing mask mandates was associated with reduced SARS-CoV-2 transmission, whereas reopening restaurants for on-premises dining was associated with increased transmission. Policies that require universal mask use and restrict any on-premises restaurant dining are important components of a comprehensive strategy to reduce exposure to and transmission of SARS-CoV-2 (1). Such efforts are increasingly important given the emergence of highly transmissible SARS-CoV-2 variants in the United States (3,4). |
COVID-19 Trends Among Persons Aged 0-24 Years - United States, March 1-December 12, 2020.
Leidman E , Duca LM , Omura JD , Proia K , Stephens JW , Sauber-Schatz EK . MMWR Morb Mortal Wkly Rep 2021 70 (3) 88-94 Coronavirus disease 2019 (COVID-19) case and electronic laboratory data reported to CDC were analyzed to describe demographic characteristics, underlying health conditions, and clinical outcomes, as well as trends in laboratory-confirmed COVID-19 incidence and testing volume among U.S. children, adolescents, and young adults (persons aged 0-24 years). This analysis provides a critical update and expansion of previously published data, to include trends after fall school reopenings, and adds preschool-aged children (0-4 years) and college-aged young adults (18-24 years) (1). Among children, adolescents, and young adults, weekly incidence (cases per 100,000 persons) increased with age and was highest during the final week of the review period (the week of December 6) among all age groups. Time trends in weekly reported incidence for children and adolescents aged 0-17 years tracked consistently with trends observed among adults since June, with both incidence and positive test results tending to increase since September after summer declines. Reported incidence and positive test results among children aged 0-10 years were consistently lower than those in older age groups. To reduce community transmission, which will support schools in operating more safely for in-person learning, communities and schools should fully implement and strictly adhere to recommended mitigation strategies, especially universal and proper masking, to reduce COVID-19 incidence. |
