More than 16,000 Virginians die of cardiovascular disease each year, with increased morbidity among Black and low-income adults. Hypertension (HTN) is the most modifiable cardiovascular disease risk factor. A community-based health intervention administered in partnership with schools may increase HTN awareness and reduce the development of unhealthy practices.

Elementary school students (n=52) attending a majority Black and low-income school participated in an educational intervention program called Teach BP that is designed to increase HTN awareness across 4 topics: knowledge of blood pressure (BP) and HTN, organ systems impacted by HTN, habits to maintain a healthy BP, and competency in operating a BP monitor.

Students' ability to define and recognize HTN increased by an average of 62.7%. Their awareness of how HTN affects the body increased by an average of 92.1%. Additionally, students demonstrated competency in operating a BP monitor.

The Teach BP program was effective at increasing students' awareness of HTN.

To observe the intervention effect of comprehensive psychological interventions on the mental health of the elderly population.

133 elderly aged 60 and above in two urban districts of Tianshui City from January 2020 to December 2020 were selected and divided into the intervention group (n=67) and the control group (n=66). The intervention group received comprehensive psychological interventions, with no intervention given to the control group. The anxiety rate, depression rate, loneliness rate and happiness rate of the two groups were collected and compared pre- and post-intervention. Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), University of California, Los Angeles Loneliness Scale (UCLA) and Memorial University of Newfoundland Scale of Happiness (MUNSH) were used to compare the psychological status of the elderly pre- and post-intervention.

Differences in the inter-group main effects and time-point main effects for SAS, SDS, UCLA, and MUNSH scores of the intervention group were significant (all p<0.05). The SAS, SDS, and UCLA scores of the intervention group were higher than those of the control group after intervention. Meanwhile, the SAS and SDS scores of the intervention group were lower than those of the control group after intervention (all p<0.05). Moreover, the MUNSH score of the intervention group was higher than that of the control group at 1-year follow-up post-intervention (p<0.05). Compared with pre-intervention values, the proportions of anxiety, depression loneliness, and happiness in the intervention group were improved at 1-year follow-up post-intervention (all P<0.05).

This study provides basis and important support for further investigations and the monitoring of health indicators in a population as fragile as the elderly. Targeted comprehensive psychological interventions can improve the negative emotions of community-dwelling elderly and maintain their physical and mental health. The "community-hospital linkage" mental health service model can improve the mental health status of community-dwelling elderly.

There is a significant research gap in the field of universal, selective, and indicated prevention interventions for mental health promotion and the prevention of mental disorders. Barriers to closing the research gap include scarcity of skilled human resources, large inequities in resource distribution and utilization, and stigma.

To assess the effectiveness of delivery by primary workers of interventions for the promotion of mental health and universal prevention, and for the selective and indicated prevention of mental disorders or symptoms of mental illness in low- and middle-income countries (LMICs). To examine the impact of intervention delivery by primary workers on resource use and costs.

We searched CENTRAL, MEDLINE, Embase, CINAHL, Global Index Medicus, PsycInfo, WHO ICTRP, and ClinicalTrials.gov from inception to 29 November 2021.

Randomized controlled trials (RCTs) of primary-level and/or community health worker interventions for promoting mental health and/or preventing mental disorders versus any control conditions in adults and children in LMICs.

Standardized mean differences (SMD) or mean differences (MD) were used for continuous outcomes, and risk ratios (RR) for dichotomous data, using a random-effects model. We analyzed data at 0 to 1, 1 to 6, and 7 to 24 months post-intervention. For SMDs, 0.20 to 0.49 represented small, 0.50 to 0.79 moderate, and ≥ 0.80 large clinical effects. We evaluated the risk of bias (RoB) using Cochrane RoB2.

Description of studies We identified 113 studies with 32,992 participants (97 RCTs, 19,570 participants in meta-analyses) for inclusion. Nineteen RCTs were conducted in low-income countries, 27 in low-middle-income countries, 2 in middle-income countries, 58 in upper-middle-income countries and 7 in mixed settings. Eighty-three RCTs included adults and 30 RCTs included children. Cadres of primary-level workers employed primary care health workers (38 studies), community workers (71 studies), both (2 studies), and not reported (2 studies). Interventions were universal prevention/promotion in 22 studies, selective in 36, and indicated prevention in 55 RCTs. Risk of bias The most common concerns over risk of bias were performance bias, attrition bias, and reporting bias. Intervention effects 'Probably', 'may', or 'uncertain' indicates 'moderate-', 'low-', or 'very low-'certainty evidence. *Certainty of the evidence (using GRADE) was assessed at 0 to 1 month post-intervention as specified in the review protocol. In the abstract, we did not report results for outcomes for which evidence was missing or very uncertain. Adults Promotion/universal prevention, compared to usual care: - probably slightly reduced anxiety symptoms (MD -0.14, 95% confidence interval (CI) -0.27 to -0.01; 1 trial, 158 participants) - may slightly reduce distress/PTSD symptoms (SMD -0.24, 95% CI -0.41 to -0.08; 4 trials, 722 participants) Selective prevention, compared to usual care: - probably slightly reduced depressive symptoms (SMD -0.69, 95% CI -1.08 to -0.30; 4 trials, 223 participants) Indicated prevention, compared to usual care: - may reduce adverse events (1 trial, 547 participants) - probably slightly reduced functional impairment (SMD -0.12, 95% CI -0.39 to -0.15; 4 trials, 663 participants) Children Promotion/universal prevention, compared to usual care: - may improve the quality of life (SMD -0.25, 95% CI -0.39 to -0.11; 2 trials, 803 participants) - may reduce adverse events (1 trial, 694 participants) - may slightly reduce depressive symptoms (MD -3.04, 95% CI -6 to -0.08; 1 trial, 160 participants) - may slightly reduce anxiety symptoms (MD -2.27, 95% CI -3.13 to -1.41; 1 trial, 183 participants) Selective prevention, compared to usual care: - probably slightly reduced depressive symptoms (SMD 0, 95% CI -0.16 to -0.15; 2 trials, 638 participants) - may slightly reduce anxiety symptoms (MD 4.50, 95% CI -12.05 to 21.05; 1 trial, 28 participants) - probably slightly reduced distress/PTSD symptoms (MD -2.14, 95% CI -3.77 to -0.51; 1 trial, 159 participants) Indicated prevention, compared to usual care: - decreased slightly functional impairment (SMD -0.29, 95% CI -0.47 to -0.10; 2 trials, 448 participants) - decreased slightly depressive symptoms (SMD -0.18, 95% CI -0.32 to -0.04; 4 trials, 771 participants) - may slightly reduce distress/PTSD symptoms (SMD 0.24, 95% CI -1.28 to 1.76; 2 trials, 448 participants).

The evidence indicated that prevention interventions delivered through primary workers - a form of task-shifting - may improve mental health outcomes. Certainty in the evidence was influenced by the risk of bias and by substantial levels of heterogeneity. A supportive network of infrastructure and research would enhance and reinforce this delivery modality across LMICs.

Over the past few decades, a community-based approach was seen to be the "gold standard" for health promotion and disease prevention, especially in the field of socially deprived neighborhoods in urban areas. Up to the beginning of the 2000s, earlier reviews provide valuable information on activities in this context. However, in their conclusions they were limited to North America and Europe. Therefore, we conducted a systematic literature review on community-based health promotion and prevention programs worldwide. The Pubmed and PsycINFO databases were screened for relevant articles published between January 2002 and December 2018, revealing 101 potentially eligible publications out of 3646 hits. After a systematic review process including searching the reference lists, 32 papers met the inclusion criteria and were included in the review. Twenty-four (75.0%) articles reported improvements in at least one health behavior, health service access, health literacy, and/or a range of health status outcomes. Large-scale community-based health promotion programs, however, often resulted in limited or missing population-wide changes. Possible reasons are methodological limitations, concurrent context effects, and limitations of the interventions used. Our results confirm that community-based interventions are promising for health promotion and disease prevention but so far their potential is not fully realized. For the future, such interventions should aim at proximal outcomes and invest in community capacity building.
