Social and Structural Determinants of Health Associated with COVID-19 Vaccine Hesitancy among Older Adults in the United States.

State-level COVID-19 vaccination rates among older adults have been uneven in the United States. Due to the immunocompromised nature of older adults, vaccine hesitancy increases the risk of morbidity and mortality. This study aims to determine the association between the social determinants of health, the structural determinants of health, and COVID-19 vaccine hesitancy among older adults in the United States. Secondary data from the Health and Retirement Study (HRS) dataset were used. A descriptive analysis and multinomial multivariable logistic regression were performed to examine the association of the independent variables-gender, age, race, immigration status, marital status, broadband internet access, social security income, Medicare coverage, education, and frequency of religious service-with the dependent variable, vaccine hesitancy. Compared to the respondents with no vaccine hesitancy and without the specific predictor, the respondents who reported religious attendance at least once/week were more likely to be "somewhat hesitant", divorced respondents had higher odds of being "somewhat hesitant", and older adults aged 65-74 years were more likely to be "very hesitant" or "somewhat hesitant" about the COVID-19 vaccine. Compared to the respondents with no vaccine hesitancy and without the specific predictor, females had higher odds of being "very hesitant", "somewhat hesitant", or a "little hesitant", and African Americans were more likely to be "very hesitant", "somewhat hesitant", or a "little hesitant" about the COVID-19 vaccine. Addressing these factors may limit the barriers to vaccine uptake reported among older adults and improve herd immunity among the immunocompromised population.

Evaluation of the Craniovertebral Angle in Standing versus Sitting Positions in Young Adults with and without Severe Forward Head Posture.

The purpose of this study was to examine the effects of standing versus sitting body position on the craniovertebral angle (CVA) in young adults without pathology; and to investigate whether mean differences between positional CVA measures in subjects with severe forward head posture (FHP) are distinct from age-matched controls with normal head posture. Ninety-eight young adults (68 women, 30 men) without pathology (OVERALL; n = 98) volunteered for the study; those with CVA > 53° were also included in a normal posture group (NORM; n = 14); those with CVA < 45° were also included in a severe FHP group (SEV; n = 15). CVA assessments were conducted in standing and sitting. Mean difference comparison of change in mean CVA between conditions revealed significantly (p < 0.05) higher CVA values in standing condition (OVERALL: 50.0 ± 5.2°; NORM: 56.6 ± 2.7°; SEV: 41.2 ± 3.2°) compared to sitting condition (OVERALL: 47.8 ± 5.7°; NORM: 55.9 ± 2.8°; SEV: 39.0 ± 4.0°). Mean difference comparison of between-group change in mean CVA between conditions revealed greater CVA change (p < 0.05) in the SEV group (2.2 ± 2.1°) versus the NORM group (0.8 ± 1.2°). Sitting CVA values may be lower (indicating greater FHP) than standing CVA values in young adults. Differences between standing and sitting CVA measures may be greater in young adults with severe FHP compared to peers with normal head posture. Study findings support standing as a standardized body position for CVA assessment in young adults without pathology.

Running-Related Overuse Injuries and Their Relationship with Run and Resistance Training Characteristics in Adult Recreational Runners: A Cross-Sectional Study.

This study aimed to characterize running-related injuries (RRIs), explore their relationship with run and resistance training (RT) parameters, and identify perceived prevention measures among adult recreational runners. An anonymous online survey was designed and distributed via social media and email. Data were analyzed with chi-square, t-test, or analysis of variance (ANOVA), with significance accepted at p ≤ 0.05. Data from 616 participants (76.8% female, age: 42.3 ± 10.5 y) were analyzed. Most runners (84.4%) had an injury history, with 44.6% experiencing one in the past year. The most common RRI sites included the foot/ankle (30.9%) and knee (22.2%). RRI prevalence was higher in those running >19 miles weekly (48.4%, p = 0.05), but there were no differences based on RT participation status. Among those using RT, relatively more RRIs were observed in runners who trained the hip musculature (50.3%, p = 0.005) and did not include the upper body (61.6%, p < 0.001). A disproportionately high RRI prevalence was found for several of the other risk-reduction strategies. RRIs remain a substantial problem, particularly around the ankle/foot and knee. Higher run volume and performance motives were positively associated with RRIs. Most runners incorporated RRI risk-reduction techniques, with over half using RT. The current study did not determine whether preventative strategies were implemented before or after injury; therefore, prospective studies controlling for previous injuries are required to evaluate the effectiveness of RT in preventing future RRIs.

Physical Profile of Air Force Special Warfare Trainees.

Physical fitness testing in the military is commonly used to assess whether service members are physically capable of performing the diverse physical tasks that may be required for their job. Body composition can influence an individual's ability to physically perform. This study aimed to analyze the general physical profile of U.S. Air Force (USAF) special warfare candidates by assessing body composition results and physical assessment scores collected over the past four years. Male candidates (n = 1036) were 18.2 years to 39.5 years of age (M = 23.5, SD = 3.9) and weighed 78.8 kg (SD = 8.3) with a BMI of 25.0 (SD = 2.0) at 11.8% body fat (SD = 3.3) as measured using bioelectrical impedance. Body composition and fitness scores were similar to those noted in U.S. Navy special warfare candidates as well as individuals in other elite tactical units. These results highlight the normative body composition profile of individuals assessing for advanced military career fields.

The Effects of Postural Education or Corrective Exercise on the Craniovertebral Angle in Young Adults with Forward Head Posture: A Randomized Controlled Trial.

The purpose of this study was to compare the effects of three different intervention strategies, postural education (PE) and two corrective exercise programs (CEPs), on the craniovertebral angle (CVA) in young adults with forward head posture (FHP). A prospective four-arm parallel randomized controlled trial with repeated measures was performed. Seventy-nine healthy young adults (55 women, 24 men; mean age: 20.08 ± 2.19 years) with FHP were randomized into four groups: PE group, self-myofascial release + stretching group (SMRS), self-myofascial release + stretching + strengthening group (SMRSS), and a control group (CG). Participant CVA (°) was assessed before and after a 4-week intervention. Seventy-two participants completed the trial. Mean difference comparisons of within-group change in mean CVA revealed an increase in the PE (MD = 3.1, p < .01), SMRS (MD = 3.8, p < .01), and SMRSS (MD = 4.4, p < .01) groups. Mean difference comparison of between-group change in mean CVA supported greater CVA change in the SMRS and SMRSS groups compared to the CG (F(3, 68) = 5.26, p < .01, η2 = .188). All three interventions appear to be effective techniques for improving FHP in young adults, however CEPs may provide superior outcomes than PE alone. A 4-week CEP consisting of self-myofascial release + stretching may yield similar CVA enhancements as a CEP consisting of self-myofascial release + stretching + strengthening. Study findings can assist fitness professionals in designing evidence-based FHP intervention programs for young adults.

Children Receiving a Nutrition and High-Quality Early Childhood Education Intervention Are Associated with Greater Math and Fluid Intelligence Scores: The Guatemala City Municipal Nurseries.

Background: About 47% of children < 5 years of age are stunted in Guatemala. In this study, the investigators aimed to compare growth and cognitive outcomes between children in second grade that attended five Guatemala City Municipal Nurseries (GCMN) vs. same sex, grade, and age-matched children. Methods: A cross-sectional design nested in a retrospective cohort was implemented between 2015 and 2019. Children that attended the GCMN and matched controls completed a math test and validated receptive language and fluid intelligence tests. The primary caregivers completed a sociodemographic survey. General and generalized linear mixed effect models were used to compare children that attended the GCMN vs. controls. The models were adjusted by maternal education, sex, asset score, and other relevant covariates. Results: Children that attended the GCMN exhibited greater math and fluid intelligence scores relative to the controls in the adjusted models (ß = 6.48; 95% CI (2.35−10.61)) and (ß = 1.20; 95% CI (0.12−2.29)), respectively. Lower odds of stunting were significant for children who went to any early childcare institution (AOR = 0.28; 95% CI (0.09−0.89)). Conclusions: The importance of integrating nutrition and high-quality early childhood education interventions in cognitive and growth outcomes is highlighted in this study. The GCMN model may be a scalable model in similar low-resource settings.

Evidence-Based Corrective Exercise Intervention for Forward Head Posture in Adolescents and Young Adults Without Musculoskeletal Pathology: A Critically Appraised Topic.

CLINICAL SCENARIO: Habitual overuse of cellphones is on the rise among adolescents and young adults. Those who maintain a flexed neck posture when using a cellphone for extended periods possess an elevated risk for developing forward head posture (FHP). Chronic FHP can lead to painful medical disorders affecting the head, neck, and shoulders. Both stretching and strengthening exercises are advocated interventions to address this postural abnormality; however, due to a wide range of corrective exercise programming in the literature, the decision for which exercises to prescribe for this condition can be challenging for clinicians. CLINICAL QUESTION: For adolescents and young adults without musculoskeletal pathology, what are the most frequent stretching and strengthening exercises incorporated into effective FHP intervention programs supported by current randomized control trials? SUMMARY OF KEY FINDINGS: A combined total of 5 stretches and 8 strengthening exercises were identified across 3 studies of level 1b evidence that successfully impacted FHP using a combined stretching and strengthening corrective exercise intervention. The supine chin tuck and a sternocleidomastoid stretch were utilized in all 3 studies, while scapular retraction and a pectoralis stretch were included in 2 of the 3 studies. CLINICAL BOTTOM LINE: Based on the results of this appraisal, the most frequent stretches and strengthening exercises incorporated into effective FHP intervention programs supported by current randomized control trials focused on adolescents or young adults without musculoskeletal pathology include a sternocleidomastoid stretch, pectoralis stretch, the supine chin tuck, and scapular retraction. STRENGTH OF RECOMMENDATION: There is "Good" to "Excellent" evidence from 3 level 1b randomized control trials to support the inclusion of a sternocleidomastoid stretch, pectoralis stretch, the supine chin tuck, and scapular retraction exercises into a corrective exercise program to address forward head posture.

The Effect of Timing and Type of Exercise on the Quality of Sleep in Trained Individuals.

Sleep is an extremely important component for overall health and for a well-balanced training program. Recent studies have highlighted the interaction between sleep, recovery, and performance in elite and recreational athletes alike. Exercise has been known to affect the quality of sleep, nevertheless the impact is not well understood in the current research, particularly the effects of exercise timing and intensity on sleep quality. The purpose of this study was to understand if exercise timing and intensity significantly impact sleep quality among recreational exercisers. The participants involved were recreational exercisers who were self-grouped into an AM or PM exercise group. They participated in a seven-day quantitative, quasi-experimental, exploratory study wearing an Actigraph watch. The participant's intensity was also self-grouped into moderate intensity or high intensity based on criteria cut points. Data was analyzed using a factorial ANOVA to examine if there was a significant difference between exercise timing and intensity on sleep quality of the participants. There were no significant differences in sleep quality in either the time group (AM vs PM) or the intensity group (MOD vs VIG) within the four measures of sleep that were looked at throughout this study; total sleep time, sleep onset latency, sleep efficiency % and wake after sleep onset (TST, SOL, SE, and WASO). Results within both, the AM and PM group and the MOD and VIG group, results showed no significant differences. These results conclude that neither exercise intensity or timing had an effect on sleep quality.

The Effectiveness of a Physical Activity Educational Campaign in a Rural Obstetrics and Gynecology Office.

Objectives The objective of this study was to evaluate the effectiveness of an early intervention health education campaign to positively influence physical activity (PA) knowledge, intention, and performance among prenatal women and women of reproductive age. Methods This study employed a quantitative, quasi-experimental, control-group comparison design with nonprobability sampling methodology. Implemented in rural healthcare settings located in the Southeastern portion of the United States, participants included prenatal patients and patients of reproductive age (n = 325) from two separate obstetrics and gynecology (OB/GYN) offices. While the intervention group was solicited from an OB/GYN office where the information-based health education campaign was implemented, the comparison group was solicited from a comparable OB/GYN office that did not implement the health education campaign. Results The women exposed to the PA health education campaign were significantly more likely to report that PA information was provided at their physician's office, scored higher on PA knowledge, and were more likely to meet the guidelines for vigorous PA and strength training (p < 0.05). Conclusions Physical activity educational campaigns are a cost effective intervention that can be implemented in healthcare settings to promote maternal and child health.

Health-related behaviors and technology usage among college students.

OBJECTIVE: To examine associations between technology usage and specific health factors among college students. METHODS: The research employed was a quantitative, descriptive, cross-sectional design; undergraduate students enrolled in spring 2012 general health education courses were recruited to participate. To explore college students' specific technology usage and health-related behaviors, a 28-item questionnaire was utilized. RESULTS: Statistical significant differences of technology usage were found between 3 of the 4 health-related behaviors under study (BMI, sleep, and nutrition) (p < .05). CONCLUSION: As technology usage continues to evolve within the college student population, health professionals need to understand its implications on health behaviors.

Measuring exercise self-efficacy in pregnant women: psychometric properties of the pregnancy-exercise self-efficacy scale (P-ESES).

BACKGROUND AND PURPOSE: This study assessed the psychometric properties of a modified self-efficacy scale-the Pregnancy-Exercise Self-Efficacy Scale (P-ESES). METHODS: Pregnant women completed the P-ESES and physical activity questionnaires (N = 88). RESULTS: Internal consistency was confirmed by Cronbach's alpha (alpha = 0.838) and equal-length Spearman-Brown (alpha = 8.22). Squared multiple correlation coefficients were calculated showing 9 of 10 items with values greater than the desired .5. A nonrotated exploratory principal components analysis confirmed the same 9 of 10 items loaded on a single factor, accounting for 46.1% of the variance. Each item had an acceptable load value of .40 or higher. CONCLUSIONS: Initial testing of the P-ESES confirmed validity and reliability with the exception of 1 item from the original measure: "Exercising without physician approval".

Influence of age, sex, and race on college students' exercise motivation of physical activity.

OBJECTIVE: The authors examined differences in exercise motivation between age, sex, and race for college students. PARTICIPANTS: Students from 156 sections of physical activity classes at a midsize university were recruited (n = 2,199; 1,081 men, 1,118 women) in 2005-2006 and volunteered to complete the Exercise Motivation Inventory. METHODS: Quantitative, cross-sectional descriptive research design was employed. RESULTS: Significant differences were found in 3 of 14 exercise motivational subscales by age (affiliation, health pressures, and ill health avoidance) (p < .05). Males were motivated by intrinsic factors (strength, competition, and challenge) (p < .05) and females by extrinsic factors (ie, weight management and appearance) (p < .05); only 2 subscales proved not to be significant by sex. Race differences provided 8 significant differences by exercise motivations (p < .05). CONCLUSIONS: Significant differences for exercise motivations in college-aged population by demographics were documented. Understanding these differences is important for college health professionals for programming strategies and promoting physical activity.
