Moving around associated with long-term weight loss in older adults: Study - Hindustan Times
According to a study, focusing less on structured exercise and more on frequent periods of moving around the day leads to long-term weight loss in older adults.
The research has been published in the 'Obesity Journal'.
This study is the first to demonstrate that a behavioural intervention focused on moving often throughout the day produces similar short-term weight loss and better long-term weight maintenance relative to a high volume of aerobic treadmill walking.
"This research is relevant for clinicians and other healthcare providers interested in supporting long-term weight loss among older adults, and for older adults who are personally interested in weight loss and avoiding weight gain," said Jason Fanning, PhD, assistant professor in the Department of Health and Exercise Science at Wake Forest University in Winston-Salem, NC. Fanning is the corresponding author of the study.

Males and females from Forsyth County, North Carolina and surrounding areas were recruited for the study through local advertisements. Recruitment occurred in six waves between 2016 and January 2019, and the final follow-up was completed in September 2020. Participants recruited in the first four waves of this study completed procedures prior to the onset of the COVID-19 pandemic in the United States, whereas the final two waves participated during the COVID-19 quarantine orders. The analysis presented pertains to participants who completed study procedures prior to the COVID-19 quarantine orders.
A total of 183 men and women aged 65 to 85 years who were classified as having obesity based on a body mass index of 30 to 45 kg/m2 were selected. The average participant was 70 years old, primarily female, highly educated and with hypertension and arthritis as being the most self-reported, prevalent comorbidities. These traits did not statistically differ between study groups.
Participants were randomized to receive a group-based, dietary weight loss program paired with one of three physical activity recommendations: aerobic exercise and SitLess, which tasked participants with moving frequently throughout the day; aerobic exercise alone; or SitLess alone. All participants received a Fitbit Alta activity monitor at least two weeks prior to the start of the intervention, and the device was paired with a mobile health application that was tailored to each intervention arm (mHealth app; the EMPOWER Companion App).
The app facilitated contact between group members and research staff between intervention visits and was designed to facilitate self-monitoring of activity behaviours by providing group-specific, visual feedback of Fitbit activity data. Study assessments were collected by blinded research staff at baseline, after the intensive phase of intervention (six months) and at the end of the maintenance phase (18 months).
Group meeting attendance was 80 per cent in weight loss and SitLess, 84 per cent in weight loss and aerobic exercise, and 78 per cent in weight loss, aerobic exercise and SitLess. Regarding structured exercise appointments, those in weight loss and aerobic exercise attended 79 per cent of exercise sessions on average, whereas weight loss, aerobic exercise and SitLess attended 65 per cent. Average weekly application usage during the intensive phase (weeks 1-24) and the full study period (weeks 1-72) revealed that weight loss, SitLess and aerobic exercise group had the most app usage compared to the weight loss and aerobic exercise group which had the least amount of app usage. Those who received the SitLess intervention tended to view their app more frequently, which was expected, as these individuals were coached to view their activity patterns several times daily.
Counter to expectations, researchers found the weight loss, aerobic exercise and SitLess condition did not lose more weight or contributed to better weight maintenance relative to weight loss and SitLess or weight loss and aerobic exercise. Instead, only the weight loss and aerobic exercise condition demonstrated significantly more regain relative to weight loss and SitLess.
"This is encouraging evidence that "moving more, more often" is beneficial for inclusion in weight loss and weight maintenance efforts for older adults. This form of treatment option may be perceived as more accessible and feasible for people pursuing sustained weight loss since it does not require structured exercise sessions and should be explored in future research. Simplification of guidance regarding exercise to "move more, more often" to sustain weight loss is promising for clinical practice and public health efforts moving forward," said Alexandra Lee, PhD, a post-doctoral scholar in the Department of Kinesiology at The Pennsylvania State University. Lee was not associated with the research.
