“…To the best of our knowledge, several studies have examined the effect of birth weight on CRF among children and adolescents. [15][16][17][18][19][20] In line with our findings, Lawlor et al, 10 van Deutekom et al, 20 and Robic Pikel et al 18 speculated that LBW negatively affected childhood CRF even after including several potential confounders. In contrast, Ortega et al 16 did not find a significant association between birth weight and CRF in adolescents.…”

“…As far as we know, the majority of studies that have examined the association between birth weight and muscle strength revealed that LBW was unfavorably associated with body muscle strength. 15,16,18,19 In contrast to previous findings, a study by van Deutekom et al 20 suggested no association of birth weight with SBJ, whereas although the birth weight was positively associated with handgrip strength, the association was no longer observed after adjusting for child's BMI as FFM mediated 75% of the association. Moreover, another study evaluated the impact of body composition in the association of birth weight with muscle strength (hand grip strength test) and revealed that FFM completely attenuated the observed association of birth weight and test.…”

“…A few studies have examined the potential effect of birth weight on PF in children; however, most of them have included specific PF components taken into consideration in nonrepresentative samples. [15][16][17][18][19][20][21] Specifically, several studies 10,18,20 have presented negative associations between LBW and childhood CRF, whereas others did not find significant associations after adjustment for potential confounders. 16,17,19 Similarly, studies have evaluated the association between birth weight and muscle strength and have found an unfavorable association with muscle strength 15,16,18,19 or no association.…”

Background: The purpose was to examine the potential associations of birth weight and infant growth with physical fitness (PF) components in childhood. Method: A random sample of 5125 dyads of children aged 8–9 years and their mothers were evaluated. Telephone interviews were carried out with the use of a standardized questionnaire for the collection of maternal lifestyle factors. Mothers were asked to provide information contained in their medical booklets and pregnancy ultrasound records. Data from 5 PF tests were used to assess cardiorespiratory fitness, speed, and body strength. Linear regression analysis was applied to assess the associations between birth weight and infant growth with PF test performances and logistic regression analysis to evaluate the associations of normal weight versus low birth weight and normal versus accelerated infant growth with PF tests performance categories (low vs high/average). Results: Birth weight was favorably associated with cardiorespiratory fitness (b = 0.12 stage increase per SD increase in birth weight, P = .047), lower body strength (b = 1.07, P = .037), upper body strength (b = 0.10, P = .038), and speed (b = −0.04, P = .001), and infant growth was associated with upper body strength (b = 0.21 cm increase per SD increase in infant weight gain, P < .001) after adjusting for children’s body mass index and several perinatal factors. Low birth weight children had 35% increased odds for low performances in PF tests compared with their normal birth weight counterparts. Conclusion: Low birth weight negatively affects childhood PF, and hence, it could play an unfavorable role in the future health of the offspring.

“…More so than the fitness level at any other stage of life, the level of physical fitness in childhood will have a marked effect on an individual's physical development and overall health in adolescence and adulthood [ 8 , 9 ]. Thus, it seems that a priority for public health should be the monitoring of fitness, especially among the youngest, popularizing recommendations concerning daily exercise, and identifying risk factors which could hamper/harm/interfere with its natural development [ 10 ].…”

Background Physical fitness has been recognized not only as an integrated predictor of the body's functional status, but also as an important marker of health outcomes. The aim of this study was to examine the factors associated with physical fitness among 3-6-year-old children within the Tujia-Nationality settlement in the years 2005, 2010, and 2014. Methods Demographics questionnaires and fitness assessment were performed to identify the risk factors for poor physical fitness (PPF) among 3- to 6-year-old children in the years 2005, 2010, and 2014 in the area of southwest Hubei of China. Results Of the 2128 children, 495 were classified as PPF (23.3%). In 2005, the percentage of PPF children was 21.7%, and the percentage of PPF children decreased from 29.1% in 2010 to 18.8% in 2014. Furthermore, Urban area children had a significant risk of PPF than rural area children (OR=1.299, P=0.031). Three-year-old children had 2.150-fold risk of PPF as compared to 6-year-old children. The children with less than 0.5 hours of activity time per day had 1.95-fold risk of PPF as compared to those with 1-2-hour activity time per day, respectively. Underweight and overweight/obese children had 2.74-fold and 1.67-fold risk of PPF as compared to normal weight children. Children had 1.97-fold risk of PPF when their father's schooling ceased after middle school and 1.51-fold risk of PPF when their father's schooling ceased after high school, respectively. Conclusions These results demonstrated that the incidence of PPF children went up from 2005 to 2010 and then down from 2010 to 2014 within the Tujia settlement. For the children in this area, the risk factors associated with PPF included urban location, younger age, less than 1-hour activity time per day in kindergarten, underweight/overweight, low father's education level, and mother's childbearing age being less than 20 years.

Background Preterm birth and low birthweight (LBW) might be associated with reduced physical fitness, although evidence remains inconclusive. Objective To examine the influence of preterm birth and LBW on physical fitness, as well as to assess whether variables such as gestational age, birthweight, or age at assessment moderate these effects. Methods PubMed, Scopus, and PsycINFO were systematically searched from inception to 7 December 2023 for case–control and cohort studies analyzing the association between preterm birth or LBW (or gestational age or birthweight as continuous variables) with at least one physical fitness-related outcome (i.e., cardiorespiratory fitness (CRF), muscle strength, flexibility, speed, agility). Random-effects meta-analysis and meta-regression models were used to estimate the pooled effect size, as well as to examine potential associations between the magnitude of the effect and gestational age, birthweight, or age at assessment. Results Fifty-two studies (n = 920,603 participants, average age ranging from 4.7 to 34.4 years) were included. Preterm birth was associated with reduced CRF (standardized mean difference (SMD) = −0.38, 95% confidence interval (CI) = −0.51 to −0.25) and muscle strength (SMD = −0.44, 95% CI = −0.79 to −0.08). LBW was associated with reduced CRF (SMD = −0.40, 95% CI = −0.64 to −0.17), muscle strength (SMD = −0.18, 95% CI = −0.24 to −0.13), flexibility (SMD = −0.11, 95% CI = −0.22 to −0.01), and agility (SMD = −0.99, 95% CI = −1.91 to −0.07). Meta-regression analyses showed that a lower gestational age or birthweight were associated with larger reductions in physical fitness, whereas no consistent association was found for the age at assessment. Conclusion Both preterm birth and LBW seem associated with reduced physical fitness regardless of age, with larger reductions overall observed in individuals with lower gestational age or birthweight. These findings might support the implementation of preventive strategies (e.g., fitness monitoring and physical exercise interventions) in these populations through the life course.
