Risk of death from undernutrition is thought to be higher in younger than in older children, but evidence is mixed. Research also demonstrates sex differences whereby boys have a higher prevalence of undernutrition than girls. This analysis described mortality risk associated with anthropometric deficits (wasting, underweight and stunting) in children 6–59 months by age and sex. We categorised children into younger (6–23 months) and older (24–59 months) age groups. Age and sex variations in near-term (within 6 months) mortality risk, associated with individual anthropometric deficits were assessed in a secondary analysis of multi-country cohort data. A random effects meta-analysis was performed. Data from seven low-or-middle-income-countries collected between 1977 and 2013 were analysed. One thousand twenty deaths were recorded for children with anthropometric deficits. Pooled meta-analysis estimates showed no differences by age in absolute mortality risk for wasting (RR 1.08, p = 0.826 for MUAC < 125 mm; RR 1.35, p = 0.272 for WHZ < −2). For underweight and stunting, absolute risk of death was higher in younger (RR 2.57, p < 0.001) compared with older children (RR 2.83, p < 0.001). For all deficits, there were no differences in mortality risk for girls compared with boys. There were no differences in the risk of mortality between younger and older wasted children, supporting continued inclusion of all children under-five in wasting treatment programmes. The risk of mortality associated with underweight and stunting was higher among younger children, suggesting that prevention programmes might be justified in focusing on younger children where resources are limited. There were no sex differences by age in mortality risk for all deficits.

International audience; Objectives: To assess the impact of the COVID-19 pandemic on the use of reimbursed contraceptives in France after 15 months of the pandemic, according to age-group and updating previous data only pertaining to the first lockdown (2 months). Study design: We conducted a national register-based study by extracting all reimbursements of oral contraceptives (OC), emergency contraception (EC), intrauterine devices (IUD), and implants from the French National Health Insurance database (SNDS), which includes and covers 99.5% of the French population, in 2018, 2019, 2020 and from January 1, 2021 to April30, 2021. We calculated the expected use of contraceptives in 2020 and 2021 in the absence of the pandemic, based on 2018 and 2019 usage and taking annual trends into account. We assessed the difference between observed and expected dispensing rates by contraceptive type and by age-group (≤18 years old, 18< age ≤25, 25< age ≤35, >35). Results: Dispensing of all contraceptives decreased compared to expect dispensing numbers: −2.0% for OC, −5.3% for EC, −9.5% for LNG-IUS, −8.6% for C-IUD, and −16.4% for implant. This decrease in the dispensing of contraceptives was observed in all age-groups, but mainly concerned women under the age of 18 years (−22% for OC, −10% for EC, −37.2% for LNG-IUS, −36.4% for C-IUD, −26.4% for implant) and those aged 18 to 25 (−5.1% for OC, −11.9% for EC, −18.1% for LNG-IUS, −15.9% for C-IUD, −17.6% for implants). Conclusions: Our study showed that the dispensing of contraceptives in France was markedly impacted by the COVID-19 pandemic. Prescriptions for long-acting contraceptive use and women under the age of 25 years were the most substantially impacted. Ensuring access to contraceptive methods during health emergencies must be a public health policy priority. Implications: The COVID-19 pandemic strongly impacted the dispensing of contraceptives in France with varying degrees of decreased dispensing according to the type of contraceptive, the age-group and the level of pandemic-related restrictions. The impact of these restrictions on unintended pregnancy at the population level remains undetermined.
