“…Our results suggest that variations in lifestyle behaviors, however important, have had a limited impact on body weight changes. Our results are in line with another study evaluating changes in eating habits in France and possible changes in food behavior and lifestyle in France among the general population [23] or students [24] and close countries [25].…”

Background: The COVID-19 pandemic has imposed local lockdowns resulting in strong disruptions in our lifestyles and dietary behaviors. This study aimed to determine how the lockdown in France affected these behaviors and weight during the lockdown and in a one month follow up period of time after the end of the lockdown. Methods: The study design was a longitudinal cohort, among French adults. A total of 593 participants (68.6% female), with a mean age of 42.2 years (SD = 15.2) completed a self-reported questionnaire on four occasions spaced one month apart, from the beginning of the lockdown starting 17 March 2020, until one month after its end (mid-June 2020). Clusters of participants were formed using the non-supervised k-means algorithm. Results: The mean weight gain after one month of lockdown was 0.56 kg (SD = 0.6). The cluster analysis exposed three different patterns of behavioral changes, despite no significant differences in age or BMI between clusters. These three groups have experienced different weight change dynamics over the follow-up duration. The first cluster (n = 210) reported fewer changes in sleep quality and quantity and less change in snacking frequency (p ≤ 0.001). The second cluster (n = 200) reported significantly lower levels of stress than the other clusters (p ≤ 0.001). The third cluster (n = 183) differed from the others, with a more degraded quality of sleep reported throughout the lockdown (p ≤ 0.01). However, changes in eating behaviors and body weight were not significant. Conclusions: During the lockdown, behavioral changes occurred, both health-favorable and non-health-favorable, yet they had a minor impact on eating behaviors and reported body weight once the restrictive measures were lifted. The identification of three patterns suggests that, in such constraining situations, personalized recommendations should be provided.

“…Furthermore, the present study reinforces the necessity of additional investigations regarding salt intake and maybe a sodium-focused food frequency questionary. Lastly, this study was conducted before the COVID-19 pandemic, that is a well-known factor that led to changes in nutritional behaviors [28][29][30]. However, the major changes in nutritional behaviors during the COVID-19 pandemic were related to the lockdown [28][29][30], what occurred only in the earliest moments of pandemic in Brazil.…”

Background Conditions related to iodine status (IS) in pregnancy should be addressed to help public health strategies. In the present study, we evaluated diet quality (DQ) and its relationship with IS in pregnant women from a coastal Brazilian state where table salt is iodine fortified. Methods In a cross-sectional study, 199 women were evaluated on three different days of their first trimester of pregnancy. In every visit, a urinary spot sample was requested to assess urinary iodine concentration (UIC); and a 24-hour dietary recall related to the time that they collected the urine was also applied by a nutritionist. Total and component scores were estimated for the Healthy Eating Index-2015 (HEI-2015). The association between DQ and IS was evaluated, considering adequate UIC as the reference group (RG). Results The median total score for HEI-2015 was 45.8 points, being higher in the insufficient UIC than in RG (48.1 vs. 41.3 in the RG; p = 0.04). Insufficiency of iodine was related to higher scores in “whole fruit” (B = 0.712 [CI: +0.421/+1.002]), “total fruit” (B = 0.744[-0.002/+0.006]), “total vegetables” (B = 0.678([+ 0.444/+0.913]) and “refined grains” (B = 0.685 [+ 0.406/+0.964]). On opposite, excessive IS was related to lower scores in the same components. Conclusions pregnant women with insufficient IS had better diet quality, with higher consumption of fruits and vegetables, as also lower intake of refined grains. In contrast, poor DQ was associated with excessive UIC during pregnancy. The necessity of iodine supplementation for pregnant women should be better explored even in a region adopting iodine fortified table salt as public health policy.

Background: The COVID-19 lockdown had a profound effect on everyday life, including sleep health. This systematic review and meta-analysis evaluated changes in quantitative sleep parameters during the first lockdown compared with pre-lockdown in the general population. Methods: A search in scientific databases was performed to identify eligible observational studies from inception to 8 February 2023. We performed a random effects meta-analysis of those studies reporting (a) means of sleep duration, time in bed (TIB), and sleep timing (bedtime and wake-up time); (b) the percentages of atypical sleep duration before and during the lockdown; (c) the percentages of change in sleep duration and sleep timing. Results: A total of 154 studies were included. A small increase in sleep duration (0.25 standardized mean difference, 95% CI 0.180–0.315) was found, with 55.0% of the individuals reporting changes, predominantly an increase (35.2%). The pooled relative risk for sleeping more than 8/9 h per night was 3.31 (95% IC 2.60–4.21). There was a moderately significant delay in sleep timing and a surge in napping. Conclusion: An increase in sleep duration and napping, and delayed sleep timing were observed. High-quality studies should evaluate whether these parameters have now become chronic or have returned to pre-lockdown values.
