Background: This study aimed to evaluate the effects of an internet-based and teacher-facilitated sexuality education package on the sexual knowledge and attitudes of Chinese adolescents. Methods: Six middle schools where no sexuality education had been performed with a total of 501 adolescent students (245 males and 256 females) were included in the trial. In total, 14 classes were randomly assigned to the intervention (internet-based sexuality education package) or the control group (classes were conducted as per normal). Students’ sexual knowledge and attitudes were assessed at the baseline, at the end of the intervention, and 12 months after the intervention. Generalized linear models were employed to assess the effects of the intervention. Results: Positive effects of the intervention were observed on sexual knowledge (β = 4.65, 95% CI: 4.12—5.17) and attitudes (β = 1.25, 95% CI: 1.00—1.50) at the end of the intervention. After 12 months, the effects sustained but the magnitude declined for sexual knowledge (β = 2.39, 95% CI: 1.85—2.93) and attitudes (β = 0.49, 95% CI: 0.23—0.75). There were no significant differences between male and female students. Conclusions: Although further modifications are required, the sexuality education package can increase the accessibility of comprehensive sexuality education to adolescents in rural areas in China.

BACKGROUND A low test positivity rate is key to keeping the COVID-19 pandemic under control. Several migrant groups in Norway have seen higher rates of confirmed COVID-19 and related hospitalizations, while test positivity has remained high in the same groups. Social media sponsored ads have been an important part of the government’s strategy to reach these groups. OBJECTIVE In this study we aimed to investigate whether such a targeted Facebook campaign increased the rate of testing in certain migrant groups. METHODS We randomly assigned 386 Norwegian municipalities and city districts, to intervention or control groups. Individuals born in Syria, Pakistan, Eritrea, Turkey, Russia and Iraq residing in intervention areas were targeted with a social media campaign aiming at increasing the COVID-19 test rate. The campaign message was in simple language and conveyed in the users’ main language or in English. RESULTS During the follow-up period of two weeks, the predicted probability of conducting a COVID-19 test was 4.82 % (CI: 4.47 % - 5.18 %) in the control group, and 5.58 % (CI: 5.20 % - 5.99 %) in the intervention group (P=.004). CONCLUSIONS Our targeted social media intervention led to a modest, but potentially important, increase in test rates among migrants in Norway.

Abstract Background: Knee osteoarthritis (KOA) is a common joint disease in people over 60 years old. Exercise therapy is one of the most effective non-pharmacological treatments for KOA, but low exercise adherence needs to be improved. The present study aimed to evaluate the effect of the transtheoretical model-lead home exercise intervention (TTM-HEI) program on exercise adherence, KOA symptoms and knee function in older adults with KOA. Methods: A two-arm, superiority, assessor-blinded, cluster randomized trial was conducted. Community-dwelling older adults with KOA were recruited from 14 community centers in Beijing, China via print and social media advertisements from April to October 2018. The intervention was a two-stage and 24-week transtheoretical model-based exercise program, and the control group underwent a same length but non-theory-based exercise program. Exercise adherence was measured by an 11-point numerical self-rating scale at weeks 4, 12, 24, 36, and 48 after the program started. KOA symptoms (pain intensity and joint stiffness) and knee function (lower limb muscle strength and balance) were measured at baseline, week 24, and week 48. Latent growth model (GLM), repeated measures ANOVA and independent t-test were the main statistical tests.Results: A total of 189 older adults (intervention group: n = 103, control group: n = 86) were enrolled. Differences of any outcome measures at baseline were not significant between groups. The growth rate of exercise adherence in the intervention group increased 2.175 units compared with the control group (unstandardized coefficient of slope on group B2 = 2.175, p < 0.001), and the intervention program maintained participants’ exercise adherence with 5.56 (SD = 1.00) compared with 3.16 (SD = 1.31) in the control group at week 48. In addition, TTM-HEI program showed significant effects on relieving KOA symptoms and improving knee function.Conclusion: The TTM-HEI could improve the participants’ exercise adherence, knee osteoarthritis symptoms and knee function over time.

AbstractObjectiveThe number of extremely thin young women has increased and education at school on maintaining an optimal weight has become important. The aim of the present study was to assess the effectiveness of a group-based home-collaborative dietary education (HCDE) programme to maintain appropriate dietary intake compared to conventional school classroom education.DesignTwo-arm cluster randomized controlled trial. Twelve classes were randomly assigned as clusters to either the HCDE group or the control group. Each participant in the HCDE group received twelve sessions of group counselling aimed at increasing energy intake at breakfast by modifying dietary intake and adopting appropriate habits. The hypothesis underlying the study was that after 6 months of HCDE the total energy intake would be increased by 627 kJ from baseline (primary endpoint). Secondary outcomes were differences in intake of various nutrients from baseline. Outcome measures after log transformation were examined by t tests and linear mixed models (crude and baseline-adjusted).SettingYoung women among Japanese female adolescents in Tokyo.SubjectsFour hundred and seventy-four participants aged 13–15 years.ResultsStudents in twelve classes were used for analysis (n 459). Energy intake was decreased in many of the classes during the 6-month period, especially for those in the control group. After adjustment for the baseline value, significant increases in energy intake and protein, calcium, magnesium and iron intakes at breakfast were observed (P < 0·05)ConclusionsAlthough energy intake was increased in the HCDE group compared to the control group, further study of the HCDE is warranted.

The Impact

Abstract Background Higher density of Neisseria meningitidis carriage may be associated with transmission of the meningococcus. Our aim was to establish the impact of meningococcal B (4CMenB) vaccine on N. meningitidis carriage density. Methods We compared 4CMenB vaccine to control among 913 South Australian students aged approximately 15–18 years in a cluster randomized trial who had N. meningitidis carriage at 12 months. Oropharyngeal swabs were collected at baseline and 12 months later to detect N. meningitidis carriage. Colony-forming units per milliliter (CFU/mL) were estimated by generating a standard curve that plotted quantitative polymerase chain reaction cycle threshold values against log-normalized CFU. Results Among the 913 students with N. meningitidis carriage at 12 months, there was no difference in mean carriage density between the vaccinated (n = 434; 3.80 log CFU/mL [standard deviation {SD}, 1.29]) and control group (n = 479; 3.73 log CFU/mL [SD, 1.30]; P = .51). Higher N. meningitidis carriage density at baseline was associated with an increase in the odds of persistent carriage at 12 months (n = 504; odds ratio [OR] per 1.0 log CFU/mL increase in density, 1.36 [95% confidence interval {CI}, 1.17–1.58]; P &lt; .001). Students with baseline carriage who were vaccinated had decreased persistent N. meningitidis carriage at 12 months compared to unvaccinated students (81/260 [31%] vs 105/244 [43%]; OR, 0.60 [95% CI, .40–.90]; P = .01). Conclusions 4CMenB vaccine did not reduce carriage density of N. meningitidis 12 months postvaccination, despite increased carriage clearance. Higher carriage density is likely to enable transmission through prolonged periods of population exposure. Clinical Trials Registration NCT03089086.

Abstract Background We determined whether an audit on the adherence to guidelines for hospital-acquired pneumonia (HAP) can improve the outcomes of patients in intensive care units (ICUs). Methods This study was conducted at 35 ICUs in 30 hospitals. We included consecutive, adult patients hospitalized in ICUs for 3 days or more. After a 3-month baseline period followed by the dissemination of recommendations, an audit on the compliance to recommendations (audit period) was followed by a 3-month cluster-randomized trial. We randomly assigned ICUs to either receive audit and feedback (intervention group) or participate in a national registry (control group). The primary outcome was the duration of ICU stay. Results Among 1856 patients enrolled, 602, 669, and 585 were recruited in the baseline, audit, and intervention periods, respectively. The composite measures of compliance were 47% (interquartile range [IQR], 38–56%) in the intervention group and 42% (IQR, 25–53%) in the control group (P = .001). As compared to the baseline period, the ICU lengths of stay were reduced by 3.2 days in the intervention period (P = .07) and by 2.8 days in the control period (P = .02). The durations of ICU stay were 7 days (IQR, 5–14 days) in the control group and 9 days (IQR, 5–20 days) in the intervention group (P = .10). After adjustment for unbalanced baseline characteristics, the hazard ratio for being discharged alive from the ICU in the control group was 1.17 (95% confidence interval, .69–2.01; P = .10). Conclusions The publication of French guidelines for HAP was associated with a reduction of the ICU length of stay. However, the realization of an audit to improve their application did not further improve outcomes. Clinical Trials Registration NCT03348579.

Objectives: The Working Mind is a program designed to reduce stigmatizing attitudes toward mental illness, improve resilience, and promote mental health in the general workplace. Previous research has revealed positive program effects in a variety of workplace settings. This study advances previous work in implementing randomization and a control group to assess the intervention’s efficacy. Methods: The program was evaluated using a cluster-randomized design, with pretest, posttest, and a 3-month follow-up in 2 implementation groups across 4 sites. Results: The Working Mind program was effective at decreasing mental health stigma and increasing self-reported resilience and coping skills at the pre–post assessment in both delivery groups. The program’s effects were maintained to the time of 3-month follow-up. Qualitative data provided further evidence that participants benefited from the program. Conclusions: This study represents an advancement over past research and provides further support for efficacy of the Working Mind program. Directions for future research, including replication using rigorous methodological procedures and examination of program effects over longer follow-up intervals, are discussed.

We conducted a cluster-randomized trial in 48 rural villages of Ethiopia to assess the effect of community-led total sanitation (CLTS) on the diarrhea incidence of children. Twenty-four villages were randomly assigned to the intervention group and the other 24 were assigned to the control group. A CLTS intervention was implemented from January 2016 through January 2017. Baseline data collection was conducted during October and November 2015. At baseline, 906 children were recruited and followed-up until January 2017. These 906 children were randomly selected among all children in the 48 villages. To determine the 7-day period prevalence of diarrhea, four household-based surveys were conducted by independent data collectors at 3, 5, 9, and 10 months after the CLTS was initiated. To determine the incidence and longitudinal prevalence, the presence of daily diarrhea presence was recorded for 140 days using diary methods. The loss to follow-up rates were 95% for period prevalence and 93% for incidence and longitudinal prevalence. The incidence ratio and longitudinal prevalence ratio were 0.66 (95% confidence interval [CI], 0.45–0.97; P = 0.03) and 0.70 (95% CI, 0.52–0.95; P = 0.02) after adjusting for clustering and stratification. The relative risk of period prevalence was 0.66 (95% CI, 0.45–0.98; P = 0.04) at 3 months after initiation. Improved toilet coverage increased from 0.0% at baseline to 35.0% at 10 months in the intervention villages, whereas it increased from 0.7% to 2.8% in the control villages. Adherence to the intervention was comparable with that of previous studies; therefore, we suggest that the findings of this study are replicable.

Community-dwelling older adults with KOA were recruited from 14 community centers in Beijing, China, via print and social media advertisements from April to October 2018. The present study lasted 48 weeks, with an intervention duration of 0–24 weeks and follow-up time of 24–48 weeks. The intervention was a two-stage and 24-week TTM-based exercise program, and the control group underwent a same-length exercise program guidance without any exercise-adherence interventions. The primary outcome was exercise adherence to the prescribed home exercise program and was measured using an 11-point numerical (0=not at all through and 10=completely as instructed) self-rating scale at week 4, 12, 24, 36, and 48 after the program started. KOA symptoms (pain intensity and joint stiffness) were measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and knee function (lower limb muscle strength and balance) was measured using the Five-Times-Sit-to-Stand Test (FTSST) and the Timed Up and Go Test (TUG) at baseline, week 24 and week 48. Latent growth model (GLM), repeated measures ANOVA, and independent t-test were the main statistical tests used.Results: A total of 189 older adults (intervention group: n = 103, control group: n = 86) were enrolled. Differences of any outcome measures at baseline were not significant between groups. The growth rate of exercise adherence in the intervention group increased 2.175 units compared with the control group (unstandardized coefficient of slope on group B2 = 2.175, p < 0.001), and the intervention program maintained participants’ exercise adherence with 5.56 (SD = 1.00) compared with 3.16 (SD = 1.31) in the control group at week 48. In addition, TTM-HEI program showed significant effects on relieving KOA symptoms and improving knee function.Conclusion: Over time, TTM-HEI could improve participants’ exercise adherence, KOA symptoms, and knee function.Trial registration: This study was approved by the ethics committee (IRB00001052-17066) in July 2017 and was registered at Chinese Clinical Trails Registry (website: www.chictr.org.cn, registry number: ChiCTR1800015458).
