Methods cross-sectional conducted October 2020 1032 Bangladeshi aged ≥60 years. A semi-structured questionnaire used collect information on participants’ characteristics related information. Perceived measured using seven-item Fear Scale (FCV-19S), where cumulative score ranged from 7 35. Multiple linear regression performed identify with COVID-19. Results The mean 19.4. Participants who were concerned about ( β : 2.75, 95% CI: 1.71 3.78) overwhelmed by 3.31, 2.33 4.29) significantly more likely be fearful Moreover, felt themselves isolated others whose close friends family members diagnosed fearful.

Recent studies have shown reduced physical activity at early stages of the COVID-19 pandemic. However, there is a lack investigation on longitudinal changes in beyond lockdowns and stay-at-home orders. Moreover, it unclear if heterogeneity growth trajectories. This study aimed to explore patterns factors associated with them. Data were from UCL Social Study. The analytical sample consisted 35,915 adults England who followed up for 22 weeks 24th March 23rd August 2020. analysed using mixture models. Our analyses identified six classes trajectories, including three stable showing little change over time (62.4% total), two decreasing (28.6%), one class increasing (9%). A range found be membership such as age, gender, education, income, employment status, health. There substantial during proportion our showed persistent inactivity or activity. Given well-established link between health, increased likely both immediate long-term implications people's mental well general wellbeing. More efforts are needed promote pandemic beyond.

Outdoor recreation management perspectives were investigated based on the general perception of increased public outdoor participation during Covid-19 pandemic and supported by survey research at local, regional, national levels in Sweden. There is an interest how professionals perceived whether could identify specific implications from Covid-19/outdoor experience. Climate adaptation literature supports idea that current global challenge coupled with projections for ongoing requires a pro-active approach; this turn to climate potential consideration or guidance characteristics shares change. recreational professionals' review recent subsequent semi-structured interviews group conducted obtain detailed perceptions outcomes. Results show confirm rapid significant increase participation. Further, identified critical trends new inexperienced participants. A positive proactive list emerged as themes interviews. synthesis support goals results indicate opportunity address concerns diminishing nature experience connectedness nature.
