Market advice.

From inside the Hong kong, middle school children is split into around three college groups-bands 1, dos and you will step 3 prior to its academic end. The fresh new scaled external and internal analysis scratches of all of the pupils was in fact ordered. They was just as split into three college or university groups and you can assigned so you can secondary schools, for each and every composed of one third of the final amount out-of college students . To your SES, monthly domestic profits of HK$ 0–14,999, HK$fifteen,000–31,999 and HK$>30,100000 denoted the reduced-, medium- and you may highest-money classification, correspondingly. The newest typical-income category produces the new average monthly residential household earnings .

Analytical study

Pearson’s Tool-Second Correlation was used to calculate the latest correlations between the characteristics from thought of PL and you may PA membership. Multiple regression analysis was used to examine the fresh connection within sensed PL and you will PA quantities of people players. Detailed analytics of your participants’ demographic information, such as for example sex, amount top (junior and you may senior second), college or university band and you can SES had been considered throughout the Pearson’s Tool-Time Relationship so you can calculate the fresh correlation between seen PL and you can PA account. The newest z-scores within correlations have been calculated to look at whether those individuals trials was indeed rather additional . SPSS variation twenty two to own Screen was utilized towards the data study. The confidence top is actually set because 95% (P ? 0.05) to keep up mathematical reliability.


The new teens claimed the detected PL normally because the (±dos.dos2), (±2.11) and you may (±step 1.90) towards the about three elements, ‘feeling of care about and you will worry about-confidence’, ‘self-expression and you may telecommunications with others’ and you can ‘education and you may understanding’, correspondingly. The average daily PA some time strength was 74 minutes from the a walking speed, having 34 moments from the a moderate rate and you can twenty-seven moments at the an energetic pace, and that satisfied the principles suggesting at least 60 minutes on a daily basis out of participation in just about any MVPA (61 moments). The full time invested in different PA domain names try an average of, 47 moments at school, 17 moments home, 66 times throughout the transport and you will forty-eight minutes during recreation.

Table 1 shows the significant correlations between the perceived PL and PA levels (r = 0.227, p < 0.01) of the Hong Kong adolescents measured by the PPLI and IPAQ-A. Although the correlations are modest, components of perceived PL, intensities of PA levels and three domains (school, transportation, and recreation) of PA were significantly correlated (r = 0.067–0.292, p < 0.01). No significant correlation was found for the home domain.

A multiple linear regression was calculated to predict the PA levels of participants based on their perceived PL attributes. Preliminary analyses were performed to ensure no violations of the assumptions of normality, linearity and multicollinearity. Table 2 shows the significant regression equation (F (3, 1941) = , p < 0.01), with an R 2 of 0.052. The participants predicted PA levels were –5490 + 366.1 (sense of self and self-confidence) + (self-expression and communication with others) + (knowledge and understanding) MET minutes when the attributes of perceived PL were measured on a 5-point Likert Scale. The results showed that sense of self and self-confidence (? = 0.123, p = 0.000), self-expression and communication with others (? = 0.071, p = 0.003) and knowledge and understanding (? = 0.082, p = 0.007) were positively related to PA level. The participants' mean PA levels increased by 366.1, and MET minutes for each attribute score of perceived PL. All attributes of perceived PL were significant predictors of PA level.

The analysis group after that browsed the factors off sex, grade level, school ring and you will SES in addition to their influence on the relationship ranging from detected 321Chat PL and PA accounts, as the revealed from inside the Dining table 3. All teams demonstrated high positively correlations ranging from identified PL and you may PA.
