BACKGROUNDː The COVID-19 outbreak forced many states to introduce public health and social measures (PHSM), which may pose an obstacle to performing physical activity (PA).METHODS: This study investigated PA levels and their changes and perceived stress in a sample of 193 participants (aged 71.21 ± 4.87 years) engaged in exercise lessons prior to PSHM. Data were collected via an online survey distributed directly to the participants. The survey included two instruments: the International Physical Activity Questionnaire and the Perceived Stress Scale.RESULTS: The results indicate that sports habits may be a protective factor in staying active and meting PA recommendations. Nevertheless, there were no associations between the number of exercise lessons in the pre-COVID-19 period and PA level or the perceived change in PA during PSHM. Ability to replace the cancelled exercise lesson with PA of similar duration and intensity was negatively associated with PA levels and its change. The PSS-10 score suggests that the sample did not experience a significant increase in perceived stress, but the relationship of this outcome to PA is unclear.CONCLUSIONS: The promotion of alternative PA that could be performed during PHSM and building long-term exercise habits in older adults should be considered.

Abstract BACKGROUND Electrophysiological studies show that reductions in power within the alpha band are associated with the Alzheimer’s disease (AD) continuum. Physical activity (PA) is a protective factor that has proved to reduce AD risk and pathological brain burden. Previous research has confirmed that exercise increases power in the alpha range. However, little is known regarding whether other non-modifiable risk factors for AD, such as increased age or APOE ε4 carriage, alter the association between PA and power in the alpha band.METHODS The relationship between PA and alpha power band was examined in a sample of 113 healthy adults using magnetoencephalography. Additionally, we explored whether ε4 carriage and age modulate this association. The correlations between alpha power and gray matter volumes and cognition were also investigated.RESULTS We detected a parieto-occipital cluster in which PA positively correlated with alpha power. The association between PA and alpha power remained following stratification of the cohort by genotype. Younger and older adults were investigated separately, and younger adults only exhibited a positive relationship between PA and alpha power. Interestingly, when four groups were created based on age (younger-older adult) and APOE (E3/E3-E3/E4), only younger E3/E3 (least predicted risk) and older E3/E4 (greatest predicted risk) had associations between greater alpha power and higher PA. Among older E3/E4, greater alpha power in these regions was associated with improved memory and preserved brain structure.CONCLUSION PA could protect against the slowing of brain activity that characterizes the AD continuum, where it is of benefit for all individuals, especially E3/E4 older adults.

Background Electronic e-cigarette ever users has been increasing as of 2015, the most prevalent ever users being young adults aged 20-24 years old. The implication of e-cigarette ever user developing into long term users is a emerging public health concern. Methods Electronic cigarette usage frequency and nicotine consumption was measured through a self-administered online survey of young adults (n= 54). Survey was advertised through social media sites between January 2019 till February 2019. Descriptive and inferential statistic was conducted using NCSS 12 to examine the association between electronic cigarette usage and nicotine consumption. Results Among young adults aged 19 to 24 years old, the frequency of e-cigarette usage was 51% high usage, 31% no usage and 16% medium and low usage. For nicotine consumption, respondents were 25% daily, 40% no use, 18% infrequent, and 14.8% frequent. Conclusion There is an association between more frequent electronic cigarette usage and higher nicotine consumption among young adults in British Columbia. Frequency e-cigarette users were found to consumption nicotine at higher frequency then non users. Further research is needed to fully understand the extent of the relationship of if e-cigarette usage promotes daily nicotine consumption or daily nicotine consumption results in higher e-cigarette usage.

The relationship of objectively measured sedentary time (ST), frequency of breaks in ST, and lower extremity function (LEF) was investigated in a diverse sample aged ≥ 70 years (n = 217). Physical activity (PA) was assessed by accelerometry deriving moderate-vigorous PA (MVPA) minutes per registered hour (MVPA min · hr−1), registered ST (ST min · hr−1), and breaks in ST min · hr−1 (breaks · hr−1). LEF was assessed by the Short Physical Performance Battery. Univariate associations with overall LEF were MVPA (r = .523), ST (r = −.499), and breaks (r = .389). Adjusted linear regression including MVPA min · hr−1, ST min · hr−1, and breaks · hr−1 explained 41.5% of LEF variance. Each additional break · hr−1 was associated with 0.58 point increase in LEF. Breaks and MVPA had strongest independent associations with LEF. Promoting regular breaks might be useful in maintaining or increasing LEF and later life independence. This novel finding is important for the design of effective lifestyle interventions targeting older adults.

Latencies and peak-to-peak amplitudes of pattern-reversal evoked-potential (PREP) components of active and inactive community-dwelling healthy 61- to 77-year-olds were compared with those of active and inactive 18- to 31-year-olds to determine whether long-term physical activity involvement was associated with attenuation of age-related changes in sensory processes. Binocular PREPs were derived for each of 2 check sizes (22 × 15 ft and 41 × 30 ft of visual angle) to provide increasing challenge of spatial resolution. Analyses of the latencies revealed significant effects for age, gender, and check size such that latencies were longer for older than for young participants, men than for women, and small than for larger check sizes. Amplitudes were larger in older adults for the P100-N150 peak-to-peak difference, but physical activity history was not associated with reduction of the observed age-related increases in component latencies and amplitude. As such, physical activity does not appear to attenuate age-related decline in visual sensory processing.

Abstract This study aims to investigate the serial multiple mediation of physical activity and perceived stress in the relationship between individual social capital and quality of life (QOL) in breast cancer survivors (BCSs). This study was conducted among 520 BCSs between March and April 2017 in Shanghai, China. Data were collected using the Individual Social Capital Scale, the Health-Promoting Lifestyle Profile-II, the Perceived Stress Scale-14 and the EORTC QLQ-C30. Ordinary least-squares regression and the bootstrap method was used to test the significance of the serial multiple mediation model. The serial-multiple mediations of physical activity and perceived stress were found significant in the relationship of QOL with all five dimensions of individual social capital. The separate mediations of two single mediating variables were found significant in the relationship of QOL with control over life and feeling about the community. In the relationship of QOL with social participation, social network and social support, the separate mediation of physical activity was significant, while the separate mediation of perceived stress was not significant. A multidisciplinary team approach and a variety of delivery systems are needed to address the social, physical and psychological issues for improving QOL among BCSs.
