“…Of the studies included in this review, most of the quantitative studies were cross-sectional surveys (75.9%) aimed at detecting the relationship between SB and its correlates or outcomes. However, few studies were of a longitudinal design (13.6%), and only 4.9%, 3.1%, and 2.5% were intervention trials [54,103,118,[136][137][138]194,195], measurement studies [64,75,108,119,125], or case-control studies [21,78,84,113], respectively. The sample sizes of the included studies ranged from 26 to 1,048,594, and 20.4% of the studies were conducted using nationally representative samples.…”

Background: The negative effects of sedentary behavior (SB) on public health have been extensively documented. A large number of studies have demonstrated that high prevalence of SB is a critical factor of all-cause mortality. Globally, the frequency of SB research has continued to rise, but little is known about SB in the Chinese population. Therefore, this review was conducted to scope the research situation and to fill the gaps related to the effects of SB in the Chinese population. Methods: Using a scoping review based on York methodology, a comprehensive search of published journal articles and grey literature was carried out through 12 databases. The literature research was conducted by two authors in July 2019, and included journal articles that targeted on the Chinese population were published between 1999 and 2019. The two authors screened the records independently and included those research topics related to SB in the Chinese population. Results: The number of included studies increased from 1 to 29 per year during the analyzed period, during which, a remarkable climb happened from 8 in 2013 to 19 in July 2019. Out of the 1303 screened studies, a total of 162 studies (81 English and 81 Chinese journal articles) met the inclusion criteria in this review. Most of the included studies (66.0%) reported the overall estimated prevalence of SB, in which, 43.2% of studies reported the average time of SB, and 40.0% of studies reported the cutoff point of SB. Besides this, 54.9% and 23.5% of studies focused on the outcomes and correlates/determinants of SB, and the proportions of studies based on testing the validation of measurement tools and on interventions were 3.7% and 4.9%, respectively. Nearly all of the reviewed articles used data from cross-sectional studies (75.9%) and longitudinal studies (13.6%), while intervention trials are less developed. The majority of the studies (64.8%) used self-reported surveys, and only 3.7% studies used device-based measurement tools. Furthermore, 35.8% of the included studies were focused on children and adolescents, while only a few studies investigated infants/toddlers and older adults. Both female and male were examined in most studies, and non-clinical populations were investigated in the context of SB in a relatively large number of studies. Conclusions: The number of research articles on SB in the Chinese population published per year has increased year by year, indicating a growing interest in this research area. More studies using population subgroup samples are needed, particularly among infants/toddlers, older adults, and clinical populations. To provide stronger evidence of the determinants and outcomes of SB, longitudinal studies using device-based measures of SB are required.

“…Zero-time exercise (ZTEx) uses a foot-in-the-door approach to kick-start the integration of simple strength-and stamina-enhancing physical activity, such as simple movements and stretching while sitting or standing, into daily life. ZTEx includes easy, enjoyable and effective (3Es) exercises that do not require extra time, money or equipment, and can be done anytime, anywhere and by anybody [5]. This approach is in line with the suggestions from physical activity guidelines for Americans that moving more and sitting less will benefit nearly everyone, and some physical activity is better than none [6].…”

Our pilot trials on ZTEx for lay health promoters (n = 28), social service and related workers (n = 56) and individuals with insomnia (n = 37) showed increased physical activity and perceived well-being [5,7,8]. The foot-in-the-door approach is a compliance tactic, which offers the easiest first step to start with, the idea being that small demands are easier to meet [9].…”

Objectives: We developed and tested a very brief Zero-time exercise (ZTEx) community-based intervention to reduce sedentary behaviour and enhance physical activity and family communication in older people. ZTEx uses a foot-in-the-door approach to integrate simple strength-and stamina-enhancing physical activity into daily life at anytime, anywhere, and by anybody.Methods: A 15-minute ZTEx intervention mini workshop with demonstrations by interventionists and practice by participants was conducted in each of the 18 districts in Hong Kong for a total of 556 public housing estate residents from 2015 to 2016. 141 participants (87% female, 73% aged ≥ 50 years) completed the evaluation. Primary outcome: intention to increase physical activity. Secondary outcomes: perceived knowledge, attitude (intention and self-efficacy) and practice regarding simple strength-and stamina-enhancing physical activity (i.e. ZTEx), days spent engaged in >= 10-minute moderate or vigorous physical activities and family communication (encouraging and engaging family members in ZTEx), and sitting time.Results: Participants were enthusiastic and enjoyed the workshops. Perceived knowledge and attitude regarding sedentary behaviour, ZTEx, and family communication significantly increased immediately after the workshops (Cohen's d = 0.20 to 0.30, all p < 0.05). At the 2-week follow-up, doing ZTEx and encouraging family members to do ZTEx significantly increased by 0.7 days and 0.4 days (Cohen's d = 0.18 and 0.26, p < 0.05) respectively. Conclusion:Our findings show early evidence that a brief ZTEx community-based intervention is an innovative, enjoyable and effective approach to improve perceived knowledge, attitude, practice, and family communication regarding simple strength-and stamina-enhancing physical activity in older people.

“…To overcome these barriers, HKU-SPH created "Zero-time exercise" (ZTEx), a new approach to kick-start the integration of simple strength-and stamina-enhancing physical activity, such as simple movements and stretching while sitting or standing, into daily life. ZTEx does not require extra time, money, and equipment, and can be done anytime, anywhere and by anybody (22). ZTEx uses a foot-in-the-door approach to start exercise in small steps, building exercise self-efficacy.…”

Background: Zero-time exercise (ZTEx) is an approach integrating simple strength-and stamina-enhancing physical activity into daily life. The study evaluated the effectiveness of a community-based lifestyle-integrated physical activity intervention using ZTEx to enhance participants' physical activity, family communication, perceived health and happiness, and family harmony. Methods: A parallel group, cluster randomized controlled trial was conducted in a sample of 673 participants from eight Integrated Family Service Centers in Hong Kong. The experimental group (n = 316) received a physical activity intervention. The control group (n = 357) received information on healthy eating. Both groups received three face-to-face intervention sessions (totalling 6 h and 30 min) and 16 text messages. The primary outcome was the change in days spent engaged in ZTEx. Secondary outcomes included changes in sitting time, days engaged in moderate or vigorous physical activities, family communication (encouraging and engaging family members in ZTEx), dietary habits, perceived health and happiness, and family harmony. Self-administered questionnaires were used at baseline and at 3, 6, and 12 months. Mixed effects models with intention-to-treat analysis was used. Results: Compared with the control group at 3 months, the experimental group showed significantly greater increases of 1.3 days spent doing ZTEx (Cohen's d: 0.60), 0.3 days spent doing moderate physical activity (Cohen's d: 0.08), 0.3 days encouraging family members to do ZTEx (Cohen's d: 0.16), and 0.7 days doing ZTEx with family members (Cohen's d: 0.39) during the 7 days prior. At 3 months, the experimental group also showed a significantly greater improvement in perceived health, by a score of 0.2 (Cohen's d: 0.14). The effect sizes ranged from small to medium, with similar intervention effects at the 6-month and 1-year assessments. Compared with the experimental Lai et al. Positive Lifestyle-Integrated Physical Activity Intervention group, the control group showed a significantly greater reduction of 0.4 days on which sweetened beverages were consumed (95% CI: 0.01, 0.9, p < 0.05, Cohen's d: 0.28). The qualitative results supported the quantitative findings. Conclusions: Our findings show that a community-based lifestyle-integrated physical activity (PA) intervention can enhance physical activity, family communication, and perceived health in deprived families in Hong Kong.
