Objective: To assess child vitamin A supplementation (VAS) coverage in 2019 and 2020 and explore key factors, including COVID-19 concerns, that influenced VAS status in four sub-Saharan African countries. Design: Data from eight representative household surveys were used to assess VAS coverage. Multivariable logistic regression models examined the effect of rural/urban residence, child sex and age, caregiver education, COVID-19 concern and household wealth on VAS status. Setting: Nine (2019) and 12 (2020) districts in Burkina Faso, Côte d'Ivoire, Guinea and Mali. Participants: 28 283 caregivers of children aged 6–59 months. Results: Between 2019 and 2020, VAS coverage increased in Burkina Faso (82·2–93·1 %), Côte d'Ivoire (90·3–93·3 %) and Mali (76·1–79·3 %) and decreased in Guinea (86·0 % to 81·7 %). Rural children had a higher likelihood of VAS uptake compared with urban children in Burkina Faso (adjusted OR (aOR) = 4·22; 95 % CI: 3·11, 5·72), Côte d'Ivoire (aOR = 5·19; 95 % CI: 3·10, 8·70) and Mali (aOR = 1·41; 95 % CI: 1·15, 1·74). Children aged 12–59 months had a higher likelihood of VAS uptake compared with children aged 6–11 months in Côte d'Ivoire (aOR = 1·67; 95 % CI: 1·12, 2·48) and Mali (aOR = 1·74; 95 % CI: 1·34, 2·26). Moderate-to-high COVID-19 concern was associated with a lower likelihood of VAS uptake in Côte d'Ivoire (aOR = 0·55; 95 % CI: 0·37, 0·80). Conclusion: The increase in VAS coverage from 2019 to 2020 suggests that COVID-19 concerns may not have limited VAS uptake in some African countries, though geographic inequities should be considered.

• Glucose in solution suppressed food intake. • Subjective appetite was higher after control preload + active video game playing. • Active video game playing affected subjective emotion scores. • Net energy balance was not affected by active video game playing. Sedentary video game playing (VGP) and caloric preloads in the pre-meal environment have been shown to influence short-term food intake (FI) regulation in children. Other factors that may affect FI control include physical activity and/or heightened emotion. Therefore, we examined the effects of a glucose preload and 30 min of active VGP (aVGP) on subjective appetite, short-term FI, and subjective emotions in 9-14 year-old children. On four test mornings approximately one-week apart, twenty-seven children (sex: 15M, 12F; age: 11.3 ± 0.3 years; BMI percentile: 55.3 ± 6.1%) consumed a standardized breakfast two hours prior to consuming 250 mL of either a 50 g glucose preload or Sucralose® control. Following the preload, participants participated in 30 min of quiet sitting or aVGP. Energy expenditure was measured during aVGP via indirect calorimetry. FI from an ad libitum pizza meal was measured after each test condition. Subjective appetite and emotions were measured at baseline (0 min), during treatment (15min), and immediately before the test meal (30 min). aVGP did not affect FI, but the glucose preload decreased FI compared with the sucralose control (∆ = 157 kcal, <0.001). Although not statistically significant (p=0.12), caloric compensation was lower following the glucose preload in the aVGP condition. Subjective appetite increased with time, and was higher in the sucralose control + aVGP condition (p=0.05). Change from baseline subjective emotion scores of anger and excitement were higher (p=0.03) and lower (p=0.02) after aVGP, respectively. Neither short-term FI nor net energy balance were affected by low-intensity aVGP (energy expenditure of 34 kcal). These findings suggest that a short bout of low-intensity aVGP does not alter energy balance during the study measurement period, and may not support achieving or maintaining healthy weights in children. However, future longitudinal studies are needed to confirm such advice. [ABSTRACT FROM AUTHOR]

Vitamin A deficiency and soil‐transmitted helminth infection are serious public health problems in Kenya. The coverage of vitamin A supplementation and deworming medication (VASD) provided through mass campaigns is generally high, yet with a cost that is not sustainable, while coverage offered through routine health services is low. Alternative strategies are needed that achieve the recommended coverage of >80% of children twice annually and can be managed by health systems with limited resources. We undertook a study from September to December 2021 to compare the feasibility and coverage of VASD locally delivered by community health volunteers (CHV) ("intervention arm") to that achieved by the bi‐annual Malezi Bora campaign event ("control arm"). This comparative cross‐sectional study was conducted in sub‐counties of Siaya County using both qualitative and quantitative methods. VASD were offered through the CHS in Alego Usonga and through Malezi Bora in Bondo Sub‐County. Coverage was assessed by a post‐event coverage survey among caregivers of children aged 6–59 months (n = 307 intervention; n = 318 control). Key informant interviews were conducted with n = 43 personnel across both modalities, and 10 focus group discussions were conducted with caregivers of children aged 6–59 months to explore knowledge, attitudes and perceptions of the two strategies. VAS coverage by CHV was 90.6% [95% CI: 87.3–93.9] compared to 70.4% [95% CI: 65.4–75.4] through the Malezi Bora, while deworming coverage was 73.9% [95% CI: 69.0–78.7] and 54.7% [95% CI: 49.2–60.2], respectively. With sufficient training and oversight, CHV can achieve superior coverage to campaigns. Key messages: Innovative strategies are needed to effectively deliver vitamin A and deworming to eligible children through routine health services.Kenya's community health volunteers (CHVs) provide diverse preventive services, but do not distribute VASD.Our four month quasi‐experimental study in Siaya County utilized quantitative and qualitative methods to compare VASD added to the CHV package to the current bi‐annual Malezi Bora campaigns.VAS coverage by CHVs was higher at 90.6% [95% CI: 87.3–93.9] compared to Malezi Bora at 70.4% [95% CI: 65.4–75.4]; deworming coverage was 73.9% [95% CI: 69.0–78.7] vs. 54.7% [95% CI: 49.2–60.2], respectively.Success factors included effective incentives, comprehensive training, and strategic planning and regular review meetings at county and subcounty levels.

Context: Whereas researchers have provided estimates for the number of head impacts sustained within a youth football season, less is known about the number of plays across which such impact exposure occurs. Objective: To estimate the number of plays in which youth football players participated during the 2013 season and to estimate injury incidence through play-based injury rates. Design: Descriptive epidemiology study. Setting: Youth football. Patients or Other Participants: Youth football players (N = 2098; age range, 5-15 years) from 105 teams in 12 recreational leagues across 6 states. Main Outcome Measure(s): We calculated the average number of athlete-plays per season and per game using independent-samples t tests to compare age groups (5-10 years old versus 11-15 years old) and squad sizes (,20 versus <20 players); game injury rates per 1000 athlete-exposures (AEs) and per 10 000 athlete-plays; and injury rate ratios (IRRs) with 95% confidence intervals (CIs) to compare age groups. Results: On average, youth football players participated in 333.9 6 178.5 plays per season and 43.9 6 24.0 plays per game. Age groups (5- to 10-year-olds versus 11- to 15-yearolds) did not differ in the average number of plays per season (335.8 versus 332.3, respectively; t2086.4 = 0.45, P = .65) or per game (44.1 versus 43.7, respectively; t2092.3 = 0.38, P = .71). However, players from smaller teams participated in more plays per season (373.7 versus 308.0; t1611.4 = 8.15, P < .001) and per game (47.7 versus 41.4; t1523.5 = 5.67, P < .001). Older players had a greater game injury rate than younger players when injury rates were calculated per 1000 AEs (23.03 versus 17.86/1000 AEs; IRR=1.29; 95% CI=1.04, 1.60) or per 10 000 athlete-plays (5.30 versus 4.18/10 000 athlete-plays; IRR=1.27; 95% CI = 1.02, 1.57). Conclusions: A larger squad size was associated with a lower average number of plays per season and per game. Increasing youth football squad sizes may help reduce headimpact exposure for individual players. The AE-based injury rates yielded effect estimates similar to those of play-based injury rates.

Pediatric functional abdominal pain disorders (FAPD) are associated with increased healthcare utilization, school absences, and poor quality of life (QoL). Cost-effective and accessible interventions are needed. This multi-site study tested the effects of a 3-session cognitive-behavioral intervention delivered to parents, in person or remotely, on the primary outcome of pain severity and secondary outcomes (process measures) of parental solicitousness, pain beliefs, catastrophizing, and child-reported coping. Additional outcomes hypothesized a priori and assessed included functional disability, quality of life, pain behavior, school absences, healthcare utilization, and gastrointestinal symptoms. The study was prospective and longitudinal (baseline, 3 and 6 months follow-up) with three randomized conditions: social learning and cognitive-behavioral therapy in-person (SLCBT) or by phone (SLCBT-R) and education/support condition by phone (ES-R). Participants were children aged 7-12 with FAPD and their parents (N = 316 dyads). While no significant treatment effect for pain severity was found, the SLCBT groups showed significantly greater improvements compared to controls on process measures of parental solicitousness, pain beliefs and catastrophizing, and additional outcomes of parent-reported functional disability, pain behaviors, child healthcare visits for abdominal pain, and (remote condition only) quality of life and missed school days. No effects were found for parent and child- reported gastrointestinal symptoms, or child- reported quality of life or coping. These findings suggest that for children with FAPD, a brief phone SLCBT for parents can be similarly effective as in-person SLCBT in changing parent responses and improving outcomes, if not reported pain and symptom report, compared to a control condition.
