Nurse facilitated 5000 m running at Parkrun improves vulnerable adolescent health in a high deprivation area: A matched pair randomized control trial.

OBJECTIVE: To examine the effect of weekly nurse facilitated 5000 m running at Parkrun on markers of health in vulnerable adolescents from a high deprivation area. DESIGN: A matched pair randomized control trial. SAMPLE: Twenty-five adolescents aged 13-18, 90% identifying as Maori/Pasifika ethnicity. INTERVENTION: The intervention (INT) group participated in 6-10 Parkruns within 10 weeks, and a control group (CON) participated in one Parkrun only. A nurse facilitated the intervention offering support and encouragement at each Parkrun. MEASUREMENTS: Pre- and post-intervention testing sessions for cardiorespiratory fitness (CRF), glycated hemoglobin, body mass index (BMI), skeletal muscle mass (SMM), body fat, and hand grip strength (STR) were conducted. RESULTS: Parkrun improved CRF (F = 5.308, p = 0.035) and 5000 m time (t = 2.850, p = 0.019) by 5.5 ± 4.9 min (11.2%). Parkrun conferred a large beneficial effect on CRF (η2 = 0.249) a moderate beneficial effect on glycated hemoglobin levels (η2 = 0.119), and small beneficial effects upon SMM (η2 = 0.037) and body fat (η2 = 0.017). CONCLUSION: A weekly dose of nurse facilitated Parkrun can be recommended as a simple, accessible intervention that confers multiple beneficial effects on markers for health in adolescents from a high deprivation area.

Moderating effect of cardiorespiratory fitness on sickness absence in occupational groups with different physical workloads.

Sickness absence from work has a large adverse impact on both individuals and societies in Sweden and the costs for sickness absence were calculated to 64.6 billion Swedish kronor (approx. 5.6 billion in Euros) in 2020. Although high cardiorespiratory fitness may protect against potential adverse effects of high physical workload, research on the moderating effect of respiratory fitness in the relation between having an occupation with high physical workload and sickness absence is scarce. To study the moderating effect of cardiorespiratory fitness in the association between occupation and psychiatric, musculoskeletal, and cardiorespiratory diagnoses. Data was retrieved from the HPI Health Profile Institute database (1988-2020) and Included 77,366 participants (mean age 41.8 years, 52.5% women) from the Swedish workforce. The sample was chosen based on occupational groups with a generally low education level and differences in physical workload. Hurdle models were used to account for incident sickness absence and the rate of sickness absence days. There were differences in sickness absence between occupational groups for musculoskeletal and cardiorespiratory diagnoses, but not for psychiatric diagnoses. In general, the association between occupation and musculoskeletal and cardiorespiratory diagnoses was moderated by cardiorespiratory fitness in most occupational groups with higher physical workload, whereas no moderating effect was observed for psychiatric diagnoses. The study results encourage community and workplace interventions to both consider variation in physical workload and to maintain and/or improve cardiorespiratory fitness for a lower risk of sickness absence, especially in occupations with high physical workload.
