At the same time, they increased the guideline for vigorous activity from 60 to 75 min/week and underlined that greater amounts of activity may confer additional health benefits. However, the report still notes that activity should be performed in bouts of at least 10 min and should preferably be spread throughout the week. The shift in focus from a minimum frequency requirement to a total weekly amount provided important flexibility to accumulate activity across the week. One year later, the US Department of Health and Human Services issued the Physical Activity Guidelines for Americans, in which it was recommended that adults should participate weekly in at least 150 min of moderate-intensity or 75 min of vigorous-intensity aerobic activity or an equivalent combination of both. Furthermore, they explicitly added that activity should be accumulated in bouts of at least 10 min. These guidelines are largely similar to the 1995 recommendations, but they also incorporated vigorous-intensity activity and emphasized the additional benefits of physical activity beyond the minimum amount. These recommendations were updated by ACSM and the American Heart Association (AHA) in 2007 and stated that “all healthy adults need moderate-intensity aerobic activity for a minimum of 30 min on five days each week or vigorous-intensity aerobic activity for a minimum of 20 min on three days each week”. In 1995, the Centers for Disease Control and Prevention and the American College of Sports Medicine (ACSM) recommended that “every adult should accumulate 30 min or more of moderate-intensity physical activity on most, preferably all, days of the week”.
Thus, increasing activity levels has become a public health priority and has led to the publication of various physical activity guidelines over the past decades. Women and subjects older than 35 were less likely to meet the guidelines than men and younger subjects and thus are important groups to target in future interventions.Ĭonsistent evidence has confirmed that regular physical activity is associated with numerous health benefits and a reduced risk of several chronic diseases. The prevalence of sufficient physical activity differed greatly depending on the definition used. Smokers were 60% less likely to participate weekly in 150 min of MVPA compared to non-smokers. Educational level was positively related with accumulating 75 min/week of vigorous activity, but negatively with taking 10000 steps/day. The odds of engaging in 150 min/week MVPA or attaining a PAL of 1.75 was lower with higher age. In addition, they were 50% less likely to meet the guidelines for weight maintenance. Women had a lower probability of achieving 30 min/day MVPA on 5 days/week (OR: 0.40), or a weekly total of 150 min or 500 MET.min MVPA or 75 min of vigorous activity compared to men (OR: 0.27-0.46). Only 16.3% of men and 14.1% of women took 10000 steps/day on 7 days/week. In addition, 34.9% of men and 21.6% of women attained an average physical activity level (PAL) of 1.75 MET and thus met the criteria for weight maintenance. With regard to vigorous physical activity, 27.9% of men and 15.7% of women achieved ≥75 min/week and 12.8% and 7.0% achieved ≥20 min/day on ≥3 days/week. ResultsĨ7.2% of men and 68.1% of women achieved ≥150 min/week of moderate-to-vigorous physical activity (MVPA), but only 57.6% and 37.3% accumulated this amount as ≥30 min/day on ≥5 days/week. Logistic regressions examined the associations between socio-demographic characteristics and the odds of meeting the different guidelines. The prevalence of sufficient physical activity was calculated according to various public health guidelines. Physical activity was assessed for seven consecutive days using the SenseWear Armband. Methodsĭata were obtained from 357 Flemish men and women (41.9 ± 9.6 years). This study evaluated compliance with various physical activity guidelines and examined the associations between meeting the guidelines and socio-demographic characteristics.
In the past decades, several public health guidelines concerning physical activity have been published.
