Group advice.

Inside Hong-kong, secondary school students is divided in to around three university bands-rings 1, dos and you may 3 according to its educational conclusion. Brand new scaled external and internal analysis scratching of all of the pupils was indeed ordered. They was just as divided into around three school rings and you will assigned so you can second universities, each composed of one-third of final amount regarding people . On SES chatstep, monthly house revenues off HK$ 0–14,999, HK$fifteen,000–29,999 and you can HK$>30,100000 denoted the low-, medium- and you will high-money class, respectively. The newest typical-money class earns the newest average month-to-month home-based family income .

Mathematical data

Pearson’s Device-Time Relationship was applied so you can calculate brand new correlations between your features of seen PL and you can PA accounts. Multiple regression research was utilized to examine the association between the observed PL and you may PA quantities of men and women professionals. Descriptive analytics of participants’ demographic guidance, eg sex, levels height (junior and senior additional), school band and you will SES have been considered in the Pearson’s Device-Moment Correlation so you can calculate this new correlation anywhere between recognized PL and you will PA account. The fresh new z-ratings between the correlations was basically determined to look at whether those people samples was in fact rather some other . SPSS version twenty two to possess Window was applied into data analysis. New rely on peak was place because the 95% (P ? 0.05) to maintain statistical accuracy.

Efficiency

The new adolescents claimed the seen PL on average as the (±dos.dosdos), (±2.11) and you will (±1.90) to your around three elements, ‘sense of mind and you will self-confidence’, ‘self-phrase and you may interaction with others’ and you will ‘degree and you can understanding’, respectively. Its mediocre day-after-day PA time and power are 74 minutes on a strolling pace, which have 34 moments at the a method rate and twenty-seven times within a vigorous pace, hence met the guidelines indicating at the very least one hour each and every day out of participation in almost any MVPA (61 moments). The time invested in different PA domain names is actually an average of, 47 times at school, 17 times home, 66 times throughout transport and you can forty-eight times during athletics.

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 searched the factors out of sex, amounts peak, college band and you can SES as well as their impact on the partnership anywhere between detected PL and you will PA profile, once the revealed when you look at the Dining table step three. All teams demonstrated significant surely correlations between sensed PL and you will PA.
