Academic Performance in Middle School: Friendship Influences

The results of the Peer/Performance Relationship Study build on previous research findings demonstrating relational significance of peer influences to academic performance during adolescence. Whereas family, teachers, and friends play a significant role in a student’s academic career, extant literature about the relational dynamics between peers and academic achievement remains scarce. This study evaluated social support and negative interchanges in relation to self-reported grades in reading, mathematics, social studies, and science. Additionally, students’ gender, race, and perception of a friend’s level of school interest were measured. The sample consisted of 321 participants in the 6th, 7th, and 8th grade from three medium-sized suburban, public middle schools in the Midwest. Social support and negative interchanges were measured by scales of the Network of Relationships Inventory. Academic performance was measured as a grade point average of the scores for the four academic subjects. Results support the hypothesis that adolescents’ relationships with peers influence academic performance. Specifically, the study’s outcome demonstrates that social support was significantly and positively related to academic performance. Negative interchanges were not significantly related to academic performance. A positive correlation was found between level of school interest and academic performance. Furthermore, gender differences were found among social support, negative interchanges, and academic performance. There were no statistical differences for race. Altogether, these results are consistent with previous research findings and provide evidence for the importance of adolescent friendships and their impact on academic performance

Time Since Last Dental Clinic Visit and Self-Reported Health among the Elderly

Background. This study determined the association between time since last dental clinic visit and self-reported health among the elderly (age ≥ 65 years). Methods. Data were from the 2010 Behavioral Risk Factor Surveillance System. A logistic regression analysis was conducted to identify factors that affect the self-reported general health of the elderly. Additionally, a negative binomial regression analysis was conducted to explore the association of time since last dental clinic visit and the self-reported number of physically unhealthy, mentally unhealthy, and sad days during the past 30 days. Results. Six predictors were identified affecting the self-reported general health of the elderly. Respondents were more likely to self-report “good, very good, or excellent” general health if they: visited the dental clinic within the past year, were non-Hispanic, had healthcare coverage, had fewer permanent teeth removed, received better education and were younger. A larger lapse of time since respondents’ last dental clinic visits was associated with increased number of mentally and physically unhealthy days and an increased number of sad days during the past 30 days. Conclusions. The positive association between better general health, fewer mentally and physically unhealthy days, and fewer sad days during the past 30 days and shorter periods of time between dental visits warrants further investigation to determine a possible causal relationship between overall health and dental visits

Breastfeeding History and Risk of Stroke Among Parous Postmenopausal Women in the Women\u27s Health Initiative

Background: Stroke is the third leading cause of death among US Hispanic and non-Hispanic black women aged 65 and older. One factor that may protect against stroke is breastfeeding. Few studies have assessed the association between breastfeeding and stroke and whether this association differs by race and ethnicity. Methods and Results: Data were taken from the Women\u27s Health Initiative Observational Study with follow-up through 2010; adjusted hazard ratios for stroke subsequent to childbirth were estimated with Cox regression models accounting for left and right censoring, overall and stratified by race/ethnicity. Of the 80 191 parous women in the Women\u27s Health Initiative Observational Study, 2699 (3.4%) had experienced a stroke within a follow-up period of 12.6 years. The average age was 63.7 years at baseline. Fifty-eight percent (n=46 699) reported ever breastfeeding; 83% were non-Hispanic white, 8% were non-Hispanic black, 4% were Hispanic, and 5% were of other race/ethnicity. After adjustment for nonmodifiable potential confounders, compared with women who had never breastfed, women who reported ever breastfeeding had a 23% lower risk of stroke (adjusted hazard ratio=0.77; 95% confidence interval 0.70-0.83). This association was strongest for non-Hispanic black women (adjusted hazard ratio=0.52; 95% confidence interval 0.37-0.71). Further, breastfeeding for a relatively short duration (1-6 months) was associated with a 19% lower risk of stroke (adjusted hazard ratios=0.81; 95% confidence interval 0.74-0.89). This association appeared stronger with longer breastfeeding duration and among non-Hispanic white and non-Hispanic black women (test for trend P \u3c 0.01). Conclusions: Study results show an association and dose-response relationship between breastfeeding and lower risk of stroke among postmenopausal women after adjustment for multiple stroke risk factors and lifestyle variables. Further investigation is warranted

Electronic Monitoring Of Mom’s Schedule (eMOMSTM): Recruitment of pregnant populations with elevated BMI in a feasibility randomized controlled trial

Underrepresentation of pregnant populations in randomized controlled trials of lifestyle change interventions is concerning due to high attrition and providers’ limited clinical time. The purpose of this evaluative study was to assess intervention uptake of pregnant individuals enrolled in a three-arm feasibility randomized controlled trial, electronic Monitoring Of Mom’s Schedule (eMOMSTM), examining lifestyle changes and lactation support alone, and in combination. Measures included: (1) participation and completion rates, and characteristics of intervention completers versus other eligible participants; and (2) provider experiences with screening and enrolling pregnant participants. Pregnant people with a pre-pregnancy body mass index ≥ 25 and < 35 kg/m2 were enrolled into the eMOMSTM trial between September 2019 - December 2020. Of the 44 consented participants, 35 were randomized, at a participation rate of 35%, and 26 completed the intervention, resulting in a completion rate of 74%. Intervention completers were slightly older and entered the study earlier in pregnancy compared to non-completers. Completers were more likely to be first-time mothers, resided in urban areas, had higher educational attainment, and were slightly more racially and ethnically diverse. A majority of providers reported willingness to participate, believed the study aligned with their organization’s mission, and were satisfied with using iPads for screening. Lessons learned to guide recruitment success include use of: (1) designated research staff in combination with physician support; and (2) user-friendly technology to help mitigate time burden on physicians and their staff. Future work should focus on successful strategies to recruit/retain pregnant populations in clinical trials

Exploring the need for interventions to manage weight and stress during interconception

Interventions to manage weight and stress during the interconception period (i.e., time immediately following childbirth to subsequent pregnancy) are needed to promote optimal maternal and infant health outcomes. To address this gap, we summarize the current state of knowledge, critically evaluate the research focused on weight and stress management during the interconception period, and provide future recommendations for research in this area. Evidence supports the importance of weight and stress management during the reproductive years and the impact of weight on maternal and child health outcomes. However, evidence-based treatment models that address postpartum weight loss and manage maternal stress during the interconception period are lacking. This problem is further compounded by inconsistent definitions and measurements of stress. Recommendations for future research include interventions that address weight and stress tailored for women in the interconception period, interventions that address healthcare providers\u27 understanding of the significance of weight and stress management during interconception, and long-term follow-up studies that focus on the public health implications of weight and stress management during interconception. Addressing obesity and stress during the interconception period via a reproductive lens will be a starting point for women and their families to live long and healthy lives

Reproductive Factors and Incidence of&nbsp;Heart Failure Hospitalization in the&nbsp;Women's Health&nbsp;Initiative.

BACKGROUND:Reproductive factors reflective of endogenous sex hormone exposure might have an effect on cardiac remodeling and the development of heart failure (HF). OBJECTIVES:This study examined the association between key reproductive factors and the incidence of HF. METHODS:Women from a cohort of the Women's Health Initiative were systematically evaluated for the incidence of HF hospitalization from study enrollment through 2014. Reproductive factors (number of live births, age at first pregnancy, and total reproductive duration [time from menarche to menopause]) were self-reported at study baseline in 1993 to 1998. We employed Cox proportional hazards regression analysis in age- and multivariable-adjusted models. RESULTS:Among 28,516 women, with an average age of 62.7 ± 7.1 years at baseline, 1,494 (5.2%) had an adjudicated incident HF hospitalization during an average follow-up of 13.1 years. After adjusting for covariates, total reproductive duration in years was inversely associated with incident HF: hazard ratios (HRs) of 0.99 per year (95% confidence interval [CI]: 0.98 to 0.99 per year) and 0.95 per 5 years (95% CI: 0.91 to 0.99 per 5 years). Conversely, early age at first pregnancy and nulliparity were significantly associated with incident HF in age-adjusted models, but not after multivariable adjustment. Notably, nulliparity was associated with incident HF with preserved ejection fraction in the fully adjusted model (HR: 2.75; 95% CI: 1.16 to 6.52). CONCLUSIONS:In post-menopausal women, shorter total reproductive duration was associated with higher risk&nbsp;of&nbsp;incident HF, and nulliparity was associated with higher risk for incident HF with preserved ejection fraction. Whether&nbsp;exposure to endogenous sex hormones underlies this relationship should be investigated in future studies

Food insecurity and pre-hypertension, pre-diabetes in adult women: results from the 2007-2010 National Health and Nutrition Examination Survey

Background Being food insecure is generally defined as the limited or uncertain availability of safe and nutritious foods and is linked to poor nutrition and fully progressed diet-sensitive chronic diseases. However, little is known about the association between food insecurity and pre-clinical disease such as pre-hypertension and pre-diabetes. This study sought to examine the associations between food insecurity and pre-clinical disease among a racially/ethnically diverse population of women. Methods Using data from 2007-2010 NHANES, we examined associations between food security and pre-clinical disease among women 18-65 years. Chi-square tests were used to examine differences in demographic variables. Bivariate and multivariable generalized logistic regressions were used to generate odds ratios (ORs) with 95% confidence intervals (CIs) to assess the magnitude of associations between the presence of pre-clinical disease, sociodemographic characteristics, and food security. Results Food insecure women with very low food security (OR=2.69; 95% CI= 1.76-4.13) and low food security (OR=1.90; 95% CI= 1.20-3.02) had increased odds of having self-reported pre-hypertension. Food insecure women with very low food security (OR = 3.34; 95% CI= 1.40- 7.95), and low food security (OR = 2.81; 95% CI= 1.33- 5.93) had increased odds of pre-diabetes and pre-hypertension compared to food secure women. Conclusions Food insecurity is associated with having pre-hypertension alone or having a comorbidity of pre-hypertension and pre-diabetes among an adult female population
