Self-reported COVID-19 symptoms and perceived likelihood of suicide attempt among Latinx individuals who experience acculturative stress.

The impact of COVID-19 has led to a substantial economic and psychosocial burden on the Latinx population. However, few studies have evaluated how COVID-19 symptoms may exacerbate suicide risk indicators among Latinx persons, or the particular social determinants of health facilitating such detrimental effects. The present study examined the association between self-reported COVID-19 symptoms and suicide likelihood (i.e., self-reported perceived likelihood that one will attempt suicide in the future) among Latinx individuals within a timeframe involving high COVID-19 contagion before the onset of vaccine dissemination. Further, the possible moderating role of acculturative stress in the association between COVID-19 symptoms and suicide likelihood was examined. The sample included 200 Latinx participants (67.5% male, Mage = 34.67 years, SD = 9.15) who completed self-report measures on COVID-19 symptoms, suicide likelihood, acculturative stress, depressive symptoms, trauma symptoms, somatic symptoms, and general COVID-19 emotional impact. Findings indicated that self-reported COVID-19 symptoms were positively associated with suicide likelihood. Further, the association between COVID-19 symptoms and suicide likelihood was moderated by acculturative stress, such that the association was only statistically significant at mean or higher levels of acculturative stress but was not significant among participants with lower acculturative stress. The moderation effect was statistically significant after controlling for sociodemographic factors, depressive symptoms, trauma symptoms, somatic symptoms, and the general emotional impact of the COVID-19 pandemic. The current findings indicate that, among Latinx individuals, acculturative stress is a key social determinant of health for marked psychological distress in the context of the COVID-19 pandemic.

Metabolic cost of rope training.

Rope training, consisting of vigorously undulating a rope with the upper body, has become a popular cardiovascular training choice in fitness centers and athletic performance enhancement facilities. Despite widespread use and growing popularity, little is known about the metabolic demands of rope training. Therefore, the purpose of this study was to quantify the cardiovascular and metabolic cost from an acute 10-minute bout of rope training. Eleven physically active participants used a 15.2-m rope anchored by a post, resulting in the participant holding 7.6 m of rope in each hand. The 10-minute protocol consisted of 15 seconds of vertical double-arm waves followed by 45 seconds of rest for 10 total repetitions. The metabolic cost was estimated from heart rate, lactate, resting O2 uptake, exercise O2 uptake, and excess postexercise O2 consumption measurements. The average heart rate for the workout was 163 ± 11 b·min with peak (Equation is included in full-text article.) of 35.4 ± 5.4 mL·kg(-1)·min(-1), and peak METs were 10.1 ± 1.6. Total energy expenditure was 467.3 ± 161.0 kJ. When expressed per unit of time, EE was 41.3 ± 14.1 kJ·min(-1). The results of this study suggest an acute 10-minute bout of rope training in a vigorous-intensity workout, resulting in high heart rates and energy expenditure, which meet previously established thresholds known to increase cardiorespiratory fitness.
