Physical Fitness Among Adolescents Who are Hispanic With Overweight or Obesity.

PURPOSE: To describe cardiorespiratory, strength, muscular endurance, and flexibility fitness outcomes in a sample of adolescents who are Hispanic aged 11 to 15 years with overweight or obesity, stratified by age and sex. METHODS: The sample included 280 adolescents (mean age: 13.0 ± 0.83 years, mean body mass index percentile: 94.6). Anthropometric measures included height, weight, body mass index percentile, and waist and hip circumference. Fitness measures included handgrip strength, sit-ups in 60 seconds, sit-and-reach test, and 6-minute walk test. We report mean scores for each fitness outcome measure and correlation coefficients with anthropometric measures. RESULTS: Mean handgrip was 23.7 ± 6.48 kg, sit-and-reach test was 25.3 ± 8.13 cm, average sit-ups in 60 seconds were 19.4 ± 9.28, and 6-minute walk distance was 1960 ± 271 ft. Males outperformed females in all tests except sit-and-reach test. DISCUSSION: Compared with published fitness values of healthy weight adolescents, our sample of adolescents who are Hispanic with overweight/obesity living in southern Florida is unconditioned in terms of cardiorespiratory fitness, strength, muscular endurance, and flexibility.

HIV-related drivers of sexual compulsivity and sexuality in sexual minority men who use methamphetamine.

Although co-occurring methamphetamine (meth) use and HIV amplify the risk for neuropsychiatric comorbidities, the underlying neuroimmune mechanisms are not well characterized. We examined whether a detectable viral load and dysregulated metabolism of amino acid precursors for neurotransmitters predicted subsequent levels of sexual compulsivity and sexual sensation seeking. This 15-month longitudinal study enrolled 110 sexual minority men (SMM) living with HIV who had biologically confirmed meth use (i.e., reactive urine or hair toxicology results). Peripheral venous blood samples collected at baseline, 6 months, 12 months, and 15 months were used to measure a detectable viral load (> 40 copies/mL), the kynurenine/tryptophan (K/T) ratio, and the phenylalanine/tyrosine (P/T) ratio. The K/T and P/T ratios index dysregulated serotonin and catecholamine (e.g., dopamine) synthesis, respectively. In a cross-lagged panel model, a detectable viral load at 6 months predicted greater sexual compulsivity at 12 months after adjusting for prior levels of sexual compulsivity and recent stimulant use (ß = 0.26, p = 0.046). A greater P/T ratio at baseline predicted decreased sexual sensation seeking at 6 months (ß = - 0.25, p = 0.004) after adjusting for baseline sexual sensation seeking and recent stimulant use. Taken together, HIV replication and dysregulated catecholamine synthesis could potentiate sexual compulsivity while decreasing sexual pleasure in SMM who use meth.

Psychological and physical intimate partner violence and sexual risk behavior among South African couples: a dyadic analysis.

This study aimed to examine intimate partner violence (IPV) as it relates to both partners' perceptions of IPV and sexual behaviors, considering how their IPV might be interdependent within the relationship dynamics. The sample consisted of 713 female-male dyads in which women were pregnant and living with HIV in rural South Africa. Using an actor-partner interdependence model (APIM), we examined the interdependent influence of psychological and physical IPV on men by their female partners and psychological and physical IPV on women by their male partners on sexual risk behavior. The APIM model found there were no actor (b = -0.06, SE = 0.05, p = .221) or partner (b = -1.2, SE = 0.06, p = .056) effects contributing to protected sex by female IPV victimization. In contrast, significant actor (b = -0.28, SE = 0.06, p < .001) and partner (b = -0.29, SE = 0.06, p < .001) effects for protection were related to male IPV victimization. The model also found that the covariate of female HIV disclosure was associated with both male (b = 0.5, SE = 0.12, p < .001) and female protected sexual intercourse (b = 0.58, SE = 0.1, p < .001). Female HIV disclosure was related to an increased likelihood of protected sex by both male and female partners. As male partners reported more IPV victimization, the likelihood of protected sex between male and female partners decreased.Trial registration: ClinicalTrials.gov identifier: NCT02085356.

Symptom burden profiles in men with advanced prostate cancer undergoing androgen deprivation therapy.

To identify symptom burden profiles among men with advanced prostate cancer undergoing androgen-deprivation therapy and examine their association with baseline sociodemographic and medical characteristics and psychosocial outcomes over time. Latent profile analysis was employed to identify distinct groups based on the Expanded Prostate Index Composite and the McGill Pain Questionnaire at baseline. Psychosocial outcomes were assessed at baseline, 6- and 12-month follow-ups. Three profiles emerged: "high symptom burden," "high sexual bother," and "low symptom burden." Men with "high symptom burden" were younger and exhibited higher baseline levels of depression, stress, cancer-specific distress, and anxiety than men in the other two groups. However, men with "high symptom burden" also demonstrated improvement in these psychosocial outcomes over time. Men with advanced prostate cancer who experience multiple co-occurring symptoms demonstrate worse psychosocial adjustment. Patients with substantial symptom burden, and specifically young men, may benefit from prompt referral to supportive care services.

Influence of Male Partners on HIV Disclosure Among South African Women in a Cluster Randomized PMTCT Intervention.

Disclosure of HIV serostatus is beneficial for women, their partners, and their infants as it enables women to actively participate in preventative care (Hodgson et al. in PLoS ONE 9(11):e111421, 2014; Odiachi et al. in Reprod Health 15(1):36, 2018). Therefore, it is important that interventions addressing HIV prevention include elements that foster disclosure of HIV to partners. This study conducted in South Africa utilizes the "Protect Your Family" (PYF) behavioral intervention and compares Prevention of Mother to Child Transmission (PMTCT) among women participating in the program versus those in a control program. Within both groups, male partners were either present or not present for the intervention. The purpose of this study was to examine differential disclosure over time for individuals in the different conditions and partner involvement. A firth logistic regression revealed an interaction in the experimental condition with male partners participating (b = - 2.84, SE = 1.56, p = .012), in which female participants were less likely to disclose their HIV status over time. Findings from this study illustrate that additional efforts are needed to empower women to disclose their HIV status.

RESUMEN: Revelar su estado serológico del VIH a sus parejas es beneficioso para las mujeres, sus parejas y sus bebés, ya que les permite a las mujeres participar activamente en atención preventiva (Hodgson et al. in PLoS ONE 9(11):e111421, 2014; Odiachi et al. in Reprod Health 15(1):36, 2018). Por lo tanto, es importante que las intervenciones que aborden la prevención del VIH incluyan elementos que fomenten la revelación del estado serológico del VIH de las mujeres a sus parejas. Este estudio realizado en Sudáfrica utiliza la intervención conductual "Protege a tu familia" (PYF por sus siglas en Ingles) y compara la prevención de la transmisión de madre a hijo (PMTCT por sus siglas en Ingles) entre mujeres que participaron en el programa y las que participaron en un programa de control. Dentro de ambos grupos, los compañeros masculinos estuvieron presentes o no presentes para la intervención. El propósito de este estudio fue examinar la revelación diferente a lo largo del tiempo para individuos en diferentes condiciones y participación de pareja. Una regresión logística reveló de Firth una interacción en la condición experimental con la participación de parejas masculinas (b = − 2.84, SE = 1.56, p = .012), en las cuales las participantes femeninas tenían menos probabilidades de revelar su estado de VIH a lo largo del tiempo. Los resultados de este estudio ilustran que se necesitan esfuerzos adicionales para motivar a las mujeres a revelar su estado de VIH.

Psychometric properties of an abbreviated Childhood Family Mealtime Questionnaire among overweight and obese Hispanic adolescents.

The current family mealtime literature shows that assessments of the mealtime environment are typically self-report, yet few studies discuss validation techniques or report using validated scales. As such, the current analysis was conducted to validate one of the only published measures to assess the mealtime environment from the adolescent perspective. Specifically, the Childhood Family Mealtime Questionnaire (CFMQ) was evaluated in a sample of 280 overweight and obese Hispanic adolescents to address the need for a validated measure of the family mealtime environment in a demographic that is disproportionately affected by the current obesity epidemic. Results of exploratory and confirmatory factor analyses to evaluate the optimal factor structure, reliability, and validity for a revised, abbreviated CFMQ are presented here. The concurrent validity of the CFMQ was evaluated using correlations between the factor structures and the previously used, culturally appropriate comparable measure of family functioning. Correlations were also computed between factor scores and obesogenic outcomes (fruit and vegetable intake, added sugar intake, and physical activity). Analyses produced a revised, abbreviated version that includes 22 items (reduced from a total of 69 items) and consists of the following 4 factors: family mealtime communication (5 items), family mealtime stress (7 items), appearance weight control (5 items), and mealtime structure (6 items). Cronbach's alphas are reported for reliability. When examining CFMQ concurrent validity with the family functioning latent variable, results showed the family mealtime communication subscale ranked highest. Additionally, the family mealtime communication subscale was associated with all three obesogenic outcomes. This abbreviated CFMQ may be a useful tool for those studying family mealtime environments and their influence on obesity and its associated lifestyle behaviors.

Intergenerational cardiovascular disease risks among Hispanics living in the United States.

BACKGROUND: Few studies have assessed intergenerational associations of obesity and cardiovascular disease risks from parents to their children among Hispanic Americans. OBJECTIVES: To assess intergenerational cardiovascular associations among Hispanic families. METHODS: Using baseline data from an obesity-focused efficacy trial targeting Hispanic adolescents (n = 280) and their parents, we conducted a series of logistic regression analyses to investigate the effects of parental BMI and blood pressure on adolescents' BMI and blood pressure, respectively. RESULTS: After adjusting for significant socio-demographic variables and adolescents' lifestyle behaviours, adolescents were more than twice as likely to be in the severely obese versus overweight range when their parents had obesity (vs. non-obese; OR = 2.55, 95% CI = 1.20, 5.39) and more than twice as likely to be in the severely obese versus obese weight range (OR = 2.44, 95% CI = 1.22, 4.87) when their parents had obesity. When compared to those with normal blood pressure, adolescents who had parents with elevated blood pressure/hypertension were more than twice as likely to have elevated blood pressure (OR = 2.05, 95% CI = 1.04, 4.00) or be classified as hypertensive stage 1/2 (OR = 2.81, 95% CI = 1.31, 6.01). CONCLUSIONS: Both severe obesity and elevated blood pressure are highly associated among Hispanic parent-child dyads. Findings underscore the potential benefits of intervening with the family system.

Family Mealtime Communication in Single- and Dual-Headed Households Among Hispanic Adolescents With Overweight and Obesity.

OBJECTIVE: To investigate the association of adolescent self-report of family mealtime communication on obesity-related behaviors in single- and dual-parent households and by sex in a sample of overweight and obese Hispanic adolescents. DESIGN: Cross-sectional analysis of a randomized control trial SETTING: Eighteen middle schools in Miami-Dade County, Florida. PARTICIPANTS: Two-hundred and eighty Hispanic seventh- and eighth-grade students MAIN OUTCOME MEASURES: Physical activity, fruit and vegetable intake, and added sugar intake. ANALYSIS: Structural equation modeling. RESULTS: The findings indicate that mealtime communication was associated with fruit and vegetable consumption in boys (ß = .30; P = .001; 95% confidence interval [CI], 0.52-2.68) and physical activity in girls (ß = .26; P = .010; 95% CI, 0.16-1.30). Moreover, a single-parent household was associated with dietary consumption in boys (fruit and vegetable intake [ß= .18; P = .039; 95% CI, 0.02-2.60] but had a moderating effect on fruit and vegetable consumption in girls (ß = .21; P = .015; 95% CI, 0.14-2.19). CONCLUSIONS AND IMPLICATIONS: Family mealtime communication may impact dietary and physical activity outcomes in Hispanic adolescents with overweight and obesity, but differentially across gender and household parent makeup. These findings, together with the prevalence of single parents, point to the importance of targeting Hispanic single parents as agents of change to promote healthy lifestyle behaviors in their children via positive mealtime interactions.

Results of a Family-Based Intervention Promoting Healthy Weight Strategies in Overweight Hispanic Adolescents and Parents: An RCT.

INTRODUCTION: Hispanic adolescents in the U.S. are disproportionately affected by overweight and obesity compared with their White, non-Hispanic counterparts. This study examines the efficacy of an evidence-based family intervention adapted to target obesity-related outcomes among Hispanic adolescents who were overweight/obese compared with prevention as usual. STUDY DESIGN: This study was an RCT. SETTING/PARTICIPANTS: Participants were Hispanic adolescents who were overweight/obese (n=280, mean age=13.01 [SD=0.82] years) in the 7th/8th grade and their primary caregivers. Primary caregivers were majority female legal guardians (88% female, mean age=41.88 [SD=6.50] years). INTERVENTION: Participants were randomized into the family-level obesity-targeted intervention or referral to community services offered for overweight/obese adolescents and families (condition). Data collection began in 2015. MAIN OUTCOME MEASURES: Primary outcomes included dietary intake (e.g., reduction of sweetened beverages) and past-month moderate-to-vigorous physical activity. Secondary outcomes were BMI and family functioning assessed among adolescents and primary caregivers. RESULTS: Study analyses (2019) indicated no significant intervention effects for adolescents' primary outcomes. Intervention effects were found for parents' intake of fresh fruits and vegetables (ß=0.12, 95% CI=0.02, 0.23), added sugar (ß= -0.11, 95% CI= -0.22, -0.004), and sweetened beverages (ß= -0.12, 95% CI=-0.23, -0.02), and parents showed decreased BMI (ß= -0.05, 95% CI= -0.11, -0.01) at 6 months after baseline compared with usual prevention. Intervention effects were found for adolescent family communication (ß=0.13, 95% CI=0.02, 0.24), peer monitoring (ß=0.12, 95% CI=0.01, 0.23), and parental involvement (ß=0.16, 95% CI=0.06, 0.26) at 6 months after baseline compared with prevention as usual. CONCLUSIONS: This intervention was not effective in improving overweight/obesity-related outcomes in adolescents. The intervention was effective in improving parents' dietary intake and BMI; however, the effects were not sustained in the long term. Other intervention strategies (e.g., booster sessions, increased nutritional information) may be necessary to sustain beneficial effects and extend effects to adolescent participants.

Is working later in life good or bad for health? An investigation of multiple health outcomes.

OBJECTIVES: To examine the mutual influences between changes in work status and multiple dimensions of health outcomes (immediate memory, physical disability, and depressive symptoms) over later years. METHODS: We used a subsample of 8,524 older adults who participated in the Health and Retirement Study from 1998 to 2008 and were 62 years or older in 1998 to examine work status and health outcomes after controlling for age and background characteristics. RESULTS: We present results of cross-lagged auto-regressive models. Work status (level of work) predicted subsequent residual changes in immediate memory over time, whereas immediate memory predicted subsequent residual changes in work status over time, even after controlling for physical disability and depressive symptoms. Similar results were indicated for the associations between work status and physical disability and depressive symptoms over time. DISCUSSION: Consistent with social causation and social selection traditions, the findings support bi-directional associations among changes in work status (the level of work), immediate memory, physical disability, and depressive symptoms in later years. Practical implications are discussed.

Feasibility of postmastectomy treatment with helical TomoTherapy.

PURPOSE: To investigate the potential of helical tomotherapy for postmastectomy radiation therapy. METHODS AND MATERIALS: By use of the TomoTherapy Hi-Art II treatment-planning system (TomoTherapy Inc., Madison, WI), helical tomotherapy dose plans were developed for 5 patients and compared with the mixed-beam (electron-photon) plans with which they had been treated. The TomoTherapy plans were evaluated by use of dose-volume quantities, tumor control probability, normal tissue complication probability (NTCP), and secondary cancer complication probability (SCCP). RESULTS: The TomoTherapy plans showed better dose homogeneity in the planning treatment volume containing the chest wall and internal mammary nodes (p = 0.001) and eliminated the need for abutting fields. For the normal tissues, the TomoTherapy plans showed a smaller fractional volume receiving 20 Gy or greater for the ipsilateral lung (p = 0.05), no change in NTCP for postradiation pneumonitis, increased SCCP for each lung and both lungs together (p < 0.02), no change in the volume of the heart receiving more than 15 Gy, no change in NTCP for excess cardiac mortality, and a larger mean dose and SCCP in the contralateral breast (p < 0.001). For nonspecific tissues, the volume receiving between 5 Gy and 25 Gy and SCCP were both larger for the TomoTherapy plans (p < 0.01). Total SCCP was larger for the TomoTherapy plans (p = 0.001). CONCLUSIONS: Overall, the TomoTherapy plans had comparable tumor control probability and NTCP to the mixed-beam plans and increased SCCP. The TomoTherapy plans showed significantly greater dose homogeneity in the chest wall, which offers the potential for improved cosmesis after treatment. These factors have resulted in TomoTherapy often being the treatment of choice for postmastectomy radiation therapy in our clinic.
