Abstract
OBJECTIVES Diet is an important modifiable factor for brain health and aging. Present study aimed to explore association of dietary quality with cognitive function and poor cognition in middle-aged and older adults participating in the China Health and Nutrition Survey (CHNS). DESIGN A longitudinal study with a twenty-year follow-up. SETTING AND PARTICIPANTS Data were drawn from the CHNS 1997, 2000, 2004, 2006, 2015 and 2018. Subjects aged 55 years and more who participated in at least two waves and had completed data on socio-demographics, lifestyle, disease history, anthropometrics, dietary measure and cognitive assessment were eligible in present study. METHODS Baseline diet were assessed by 3-day 24-hour dietary recalls and used to evaluate diet quality via China Elderly Dietary Guidelines Index 2022 (CDGI 2022-E). Cognitive function was examined using part items of the Telephone Interview for Cognitive Status-modified. Three-level linear mixed effects models and three-level mixed effects logistic regression models were performed to estimate the association between diet quality and cognitive function and odds of poor cognition, respectively. RESULTS At baseline, 4173 subjects with median age of 63.7 years were recruited. Median of CDGI 2022-E total score was 44.7. Median score of global cognition was 16.0, and the proportion of people with poor cognitive function was 13.9%. Difference in global cognitive score was observed by tertiles of CDGI 2022-E (p<0.05). Significant associations of high diet quality with increment in global cognitive score [β (95%CI): 0.704 (0.394~1.015)], composite cognitive z score [0.086 (0.045~0.128)] and standardized verbal memory score [0.221 (0.122~0.320)] were observed in total subjects. Consistent associations were also found in those below 65 years at baseline. The likelihood of poor cognition in the highest tertile of CDGI 2022-E decreased by 18% (95%CI: 0.698~0.965) relative to the lowest tertile group in total population. CONCLUSIONS High diet quality may be beneficial for improving cognitive function and delaying cognitive decline in Chinese middle-aged and older population.

Changes in Anthropometric Measurements and Physical Fitness of Polish Students in 20-Year Period. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph192416885. [PMID: 36554765 PMCID: PMC9778732 DOI: 10.3390/ijerph192416885] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Revised: 12/12/2022] [Accepted: 12/13/2022] [Indexed: 05/31/2023]
Abstract
BACKGROUND Intergenerational changes are still being recorded worldwide, although their magnitude and direction may vary in different countries. The aim of this study was to determine changes in the magnitude and direction of changes in the body morphology and motor abilities of physically active adults over 20 years. METHODS Two hundred and fifty-two individuals aged 18-28 years volunteered to participate in the study. The changes were analyzed over a 20-year period (March 2001; P1 vs. March 2022; P2). The measured parameters were body height, weight, and body fat. Further, hand grip strength with dynamometer measurement, a sit-up test, a sit and reach test, and a standing long jump were performed to examine motor abilities. The results of the conducted tests were compared between subjects from both periods. RESULTS Our study confirms changes in trends concerning body morphology and motor ability performance. Higher values of body mass index and body fat were observed in P2 women, whereas these differences were not significant in men. Additionally, in terms of physical performance, the P2 group noted worse results than their peers from the past. CONCLUSION Despite young adults claiming to have similar physical activity levels to those observed in the past, they demonstrate poorer physical performance and higher body fat levels. The observed changes can be considered negative.

Secular changes in the waist, hips circumferences and selected associated indicators, among preschool children from Kraków (Poland), between 1983 and 2018. Am J Hum Biol 2022; 34:e23748. [PMID: 35333429 DOI: 10.1002/ajhb.23748] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Revised: 03/15/2022] [Accepted: 03/16/2022] [Indexed: 12/23/2022] Open
Abstract
OBJECTIVES Waist circumference and derived indicators are great for measuring the risk of abdominal obesity. The main aim of the study was to assess the changes in the waist, hips circumferences and selected associated indicators, among preschool children (3-7 years of age) from Kraków, Poland, between 1983, 2008 and 2018. METHODS The research was conducted in randomly selected kindergarten in Krakow (Poland). The 1983 cohort consisted of 1414 children and the 2008 and 2018 series included 1050 preschoolers each. Analyzed characteristics included waist and hip circumferences, body height, waist-to-hips ratio (WHR) and waist-to-height ratio (WHtR). RESULTS There was a negative secular trend regarding circumferences of the hips and waist, as well as WHtR. In girls, WHR was, the greatest in the 2018 cohort, while among boys there was a secular increase in the value of this parameter compared to the 2008 cohort, but not to the 1983 series. CONCLUSIONS The coexistence of currently noted trends with the previously described secular decrease in the prevalence of overweight/obesity and increase in trunk adiposity in the same population, suggests that WHR is preferable to body mass index in assessing the risk associated with excess adiposity in the population examined in the presented study.

Changes in the body mass index and blood pressure association across time: Evidence from multiple cross-sectional and cohort studies. Prev Med 2021; 153:106825. [PMID: 34599929 PMCID: PMC8633761 DOI: 10.1016/j.ypmed.2021.106825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 09/15/2021] [Accepted: 09/26/2021] [Indexed: 11/26/2022]
Abstract
Although body mass index (BMI) is considered a key determinant of high blood pressure, its importance may differ over time and by age group. We utilised separate data sources to investigate temporal changes in this association: 23 independent (newly sampled), repeated cross-sectional studies (Health Survey for England (HSE)) at ≥25 years (1994-2018; N = 126,742); and three British birth cohorts at 43-46 years (born 1946, 1958, and 1970; N = 18,657). In HSE, associations were weaker in more recent years, with this trend most pronounced amongst older adults. After adjustment for sex, anti-hypertensive treatment and education, the mean difference in systolic blood pressure (SBP) per 1 kg/m2 increase in BMI amongst adults ≥55 years was 0.75 mmHg (95%CI: 0.60-0.90) in 1994, 0.66 mmHg (0.46-0.85) in 2003, and 0.53 mmHg (0.35-0.71) in 2018. In the 1958 and 1970 cohorts, BMI and SBP associations were of similar magnitude yet weaker in the 1946 cohort, potentially due to differences in blood pressure measurement device. Quantile regression analyses suggested that associations between BMI and SBP were present both below and above the hypertension threshold. A weaker association between BMI and blood pressure may partly offset the public health impacts of increasing obesity prevalence. However, despite sizable increases in use of antihypertensive medication, BMI remains positively associated with SBP in all ages. Our findings highlight the need to tackle non-medical factors such as population diet which influence both BMI and blood pressure, and the utility of using multiple datasets to obtain robust inferences on trends in risk factor-outcome associations across time.

Abstract
Abstract
In the light of changes in the living conditions of populations, excess adiposity is currently a serious public health problem worldwide. The aim of this study was to assess the changes in the body fat ratio among preschool children aged 3–7 years from Kraków, Poland, between 2008 and 2018. The study group consisted of children examined in two cross-sectional studies. Analysed characteristics included triceps, calf, subscapular, abdominal and suprailiac skinfold thicknesses, and adiposity calculated according to Slaughter’s equations. The trunk adiposity index and limbs-to-trunk fat ratio were also calculated. Statistical significance was obtained using two-way ANOVA and Tukey’s tests. Lower-limb adiposity was largest in the 2008 cohort and trunk adiposity was greater in the 2018 cohort. The mean values of the trunk adiposity index and limbs-to-trunk fat ratio were lower in the 2018 cohort than in the 2008 cohort. The 2018 cohort was also characterized by a lower overall adiposity. Regardless of the lower body adiposity percentage, in 2018 there was a tendency towards the central allocation of fat tissue. This is a negative phenomenon because, especially when co-existing with reduced lower-limb adiposity, it is associated with an increased risk of metabolic and cardiovascular diseases, even in young children.

Abstract
Brain morphology is altered in both anorexia nervosa and obesity. However, it is yet unclear if the relationship between Body Mass Index-Standard Deviation Score (BMI-SDS) and brain morphology exists across the BMI-SDS spectrum, or is present only in the extremes. The study involved 3160 9-to-11 year-old children (50.3% female) who participate in Generation R, a population-based study. Structural MRI scans were obtained from all children and FreeSurfer was used to quantify both global and surface-based measures of gyrification and cortical thickness. Body length and weight were measured to calculate BMI. Dutch growth curves were used to calculate BMI-SDS. BMI-SDS was analyzed continuously and in two categories (median split). The relationship between BMI-SDS (range − 3.82 to 3.31) and gyrification showed an inverted-U shape curve in children with both lower and higher BMI-SDS values having lower gyrification in widespread areas of the brain. BMI-SDS had a positive linear association with cortical thickness in multiple brain regions. This study provides evidence for an association between BMI-SDS and brain morphology in a large sample of children from the general population and suggests that a normal BMI during childhood is important for brain development. Future studies could determine whether lifestyle modifications optimize BMI-SDS result in return to more typical patterns of brain morphology.

Secular trends in body height, body weight, BMI and fat percentage in Polish university students in a period of 50 years. PLoS One 2019; 14:e0220514. [PMID: 31369619 PMCID: PMC6675091 DOI: 10.1371/journal.pone.0220514] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2019] [Accepted: 07/17/2019] [Indexed: 11/19/2022] Open
Abstract
Objectives The aim of the study was to determine changes in the magnitude and direction of secular trends in body height, body weight, body mass index (BMI) and fat percentage in university students from a university of technology and a university of physical education in a period of 50 years. Methods The data were derived from the examinations of male students from the Warsaw University of Technology, conducted four times, in 1959, 1971, 1994, 2011, and male students from the Józef Piłsudski University of Physical Education in Warsaw, who were examined in 1963, 1972, 1996, and 2012. Body height, body weight and thickness of 2 skinfolds (triceps skinfold and abdomen skinfold) were measured. Body mass index (BMI) and fat percentage (FAT%) were also calculated. Results Current university students are taller and heavier than their peers from the previous decades, with BMI remaining within the reference range. A substantial increase in fat percentage was found in both groups. Over the period of fifty years, mean fat percentage in students from the university of technology increased by 6.3% (F1,3 = 116.56, p < 0.001, η2 = 0.3736), whereas this increase in the students from the university of physical education rose by 3.5% (F1,3 = 72.94, p < 0.001, η2 = 0.3181). Conclusion Changes in secular trends in the students from both universities are likely to be linked to the dynamic economic and systematic transformation in Poland observed in the period of the last 50 years. The period of economic transformations in the last decade was more conducive to physical development of university students than the previous period of economic crises.

Abstract
Objective To evaluate the feasibility of quantifying visceral adipose tissue (VAT) on
computed tomography (CT) and magnetic resonance imaging (MRI) scans, using
freeware, as well as calculating intraobserver and interobserver
reproducibility. Materials and Methods We quantified VAT in patients who underwent abdominal CT and MRI at our
institution between 2010 and 2015, with a maximum of three months between
the two examinations. A slice acquired at the level of the umbilicus was
selected. Segmentation was performed with the region growing algorithm of
the freeware employed. Intraobserver and interobserver reproducibility were
evaluated, as was the accuracy of MRI in relation to that of CT. Results Thirty-one patients (14 males and 17 females; mean age of 57 ± 15
years) underwent CT and MRI (mean interval between the examinations, 28
± 12 days). The interobserver reproducibility was 82% for CT (bias =
1.52 cm2; p = 0.488), 86% for T1-weighted MRI
(bias = −4.36 cm2; p = 0.006), and 88% for
T2-weighted MRI (bias = −0.52 cm2; p = 0.735).
The intraobserver reproducibility was 90% for CT (bias = 0.14
cm2; p = 0.912), 92% for T1-weighted MRI (bias =
−3,4 cm2; p = 0.035), and 90% for T2-weighted
MRI (bias = −0.30 cm2; p = 0.887). The
reproducibility between T1-weighted MRI and T2-weighted MRI was 87% (bias =
−0.11 cm2; p = 0.957). In comparison with the
accuracy of CT, that of T1-weighted and T2-weighted MRI was 89% and 91%,
respectively. Conclusion The program employed can be used in order to quantify VAT on CT, T1-weighted
MRI, and T2-weighted MRI scans. Overall, the accuracy of MRI (in comparison
with that of CT) appears to be high, as do intraobserver and interobserver
reproducibility. However, the quantification of VAT seems to be less
reproducible in T1-weighted sequences.

Abstract
BACKGROUND During their preschool years children establish nutritional and physical activity (PA) habits that may contribute to the development of overweight and obesity. OBJECTIVE To examine the evidence for effective interventions promoting healthy eating and PA in childcare settings. METHODS We searched PubMed, the Cochrane Library, and Campbell Collaboration for systematic reviews published between 2007 and 2014. Ten systematic reviews and three meta-analyses met the inclusion criteria, including a total of 22 intervention studies. Intervention studies were conducted in North America (N = 14), Europe (N = 5), Asia (N = 2), and Australia (N = 1). Half of these addressed ethnic minority groups or socially disadvantaged children. We extracted information about the effects regarding anthropometric measures, eating habits, and physical activity, as well as the characteristics of effective interventions, and summarized them narratively. RESULTS Evidence for intervention effects on anthropometric measurements was inconclusive. Seven out of nine studies showed beneficial effects on diet-related outcomes. Only isolated effects were reported on improvements in PA. Reviews indicated that interventions which comprised (1) the development of skills and competencies, (2) medium to high parental involvement, and (3) information on behavior-health links for parents were more effective. CONCLUSION Preschool-based interventions showed some early improvements in eating habits and PA. Evidence is limited by the small number of studies, a lack of methodological quality, and inconsistencies among outcome measures. Evidence regarding anthropometric measurements is still inconclusive.

Abstract
BACKGROUND Juvenile obesity is associated with multiple cardiometabolic comorbidities, which may culminate in the metabolic syndrome (MetS). METHODS Based on a narrative review, the current knowledge of prevalence and the underlying metabolic principles regarding juvenile obesity and MetS are summarized to compile up-to-date information. In addition, the role of lifestyle as well as positive and negative influencing factors are focused on. RESULTS The prevalence of MetS occurs between 1 and up to 23% in the total pediatric population and in up to 60% amongst the obese and overweight. It can be considered as the consequence of multiple processes in terms of lifestyle, perinatal programming, and (epi-)genetic pathways; however, the complex underlying mechanisms and their interplay are not completely understood. CONCLUSION Besides preventive approaches, the growing number of obese children and youth as well as its consequences call for effective and lasting therapeutic measures.

Abstract
AIM This study objectively investigated the amount and intensity of German primary school children's physical activity (PA) during different segments of the school day and explored the contribution of physical education (PE) and break times to daily moderate to vigorous PA (MVPA). SUBJECT AND METHODS PA of 294 children (7.1 ± 0.7 years, 48 % male) was objectively measured for 6 days using Actiheart®. Based on children's timetables, break times and PE periods were determined and PA was calculated individually and subsequently classified in light (1.5-3 MET), moderate (3-6 MET) and vigorous (>6 MET) intensities. Weight status was determined during a school visit. RESULTS Children spent 133 ± 61 min in MVPA; on weekdays, this amount increased significantly (141 ± 66 min, p ≤ 0.01). 45.9 % of children reached physical activity guidelines of 60 min of MVPA daily, with boys achieving this goal significantly more often than girls (65.6 vs. 28.7 %, respectively; p ≤ 0.01). PE lessons and break times accounted for 15 ± 13 min (12.7 %) and 7 ± 6 min (5.8 %) of daily MVPA, respectively. On days with PE, children spent 144 ± 68 min in MVPA, whereas on days without PE, this time decreased significantly to 122 ± 63 min (p ≤ 0.01). CONCLUSION The findings suggest that segments such as PE lessons and morning breaks are important sources for MVPA for boys and girls. This should therefore be considered for policies, timetables and curriculums in order to offer sufficient opportunities for children to be physically active during the school day.

Abstract
Surveys performed in the past 10 to 15 years show a yet unexplained stabilization or decline in prevalence rates of childhood obesity in developed countries. The projected continuous increase in obesity prevalence throughout future decades seems not to occur at present. Apparently, saturation has been reached, which might be related to societal adjustments. Hence, we postulate a cumulative effect of public health programs for obesity prevention resulting, for example, in an increase in physical activity, and a decline in television viewing and in the consumption of sugar-sweetened soft drinks by children. Effective public health programs are urgently needed for developing countries, where obesity rates in children still continued to increase during the past decade.

Abstract
OBJECTIVE To investigate patterns of care for testicular torsion and influence of hospital transfers on testicular outcomes. Hospital transfer may be a source of treatment delay in a condition where delays increase likelihood of orchiectomy. METHODS We used a retrospective cohort of Californian males with ICD-9/CPT-defined torsion from inpatient, emergency department (ED), and ambulatory surgery center (ASC) data. Logistic regression assessed predictors of orchiectomy. RESULTS Predictors of orchiectomy were ages <1 year (OR 19.2, 95% CI 6.3-58.9), 1-9 years (OR 2.7, 95% CI 1.4-5.2), and ≥40 years (OR 6.6, 95% CI 3.1-13.9) (vs. masked age). Treatment at mid-volume (vs. high-volume) facilities was associated with lower odds of orchiectomy (OR 0.5, 95% CI 0.3-0.7). Rural location, non-private insurance, and hospital transfer were associated with orchiectomy on univariate but not multivariate analysis. During 2008-2010, 2794 subjects experienced torsion (average incidence 5.08 per 100,000 males yearly). Encounters occurred in ASCs (55%), inpatient facilities (36%), and EDs (9%). 60% of subjects were privately insured, 2% experienced hospital transfer, and 31% underwent orchiectomy. CONCLUSION Our census found that most cases of testicular torsion were treated in outpatient settings. Hospital transfer was not associated with orchiectomy.

Abstract
UNLABELLED To estimate the development of prevalence rates for overweight and obesity in children starting school in Germany, data for children's height and weight out of the compulsory school enrolment examinations (SEE), conducted annually in every German federal state, were available. A former analysis of these data showed a marked increase of prevalence of overweight and obesity until 2004. The aim of this project was to give an updated overview on the development of prevalence rates for overweight and obesity in children upon school entry by including recent data until 2008. Data on measured height and weight from the yearly conducted SEE were obtained from all 16 German federal states. Overweight and obesity were defined by BMI > 90th and BMI > 97th age- and gender-related percentiles of German reference values, respectively. In 2008, the prevalence for overweight varied from 8.4% in Saxony to 11.9% in Bremen and Thuringia. The current prevalence rates for obesity ranged from 3.3% in Brandenburg and Saxony till 5.4% in Saarland. The current data from SEE by the majority of the individual states showed that the prevalence for both overweight and obesity did not increase any more after 2004 and is even declining in some states compared to the former data inquiry. Absolute decrease of prevalence rates was up to 3% for overweight and 1.8% for obesity. CONCLUSION The current data from the SEE of individual German states are based on census and showed by the majority that the prevalence of overweight and obese children starting school did not increase anymore and even declined in the last 4 years, respectively. It is supposed that the measures for prevention initiated in the 1990s and implemented afterwards have contributed to this positive development in Germany.

Abstract
OBJECTIVE To describe the effects of URMEL-ICE, a German school-based intervention for overweight prevention, on children's BMI and other measures of fat mass. METHODS A cluster-randomised controlled design was used. The intervention which focused on physical activity, TV time and soft drink consumption was integrated into a second-grade curriculum and was implemented by classroom teachers themselves. It comprised 29 teaching lessons, 2 short exercise blocks per day and 6 family homework lessons. BMI was assessed as primary outcome measure, waist circumference and skinfold thickness as secondary outcomes. Data of 945 children were analysed. RESULTS Multivariate analyses adjusted for baseline values showed no statistically significant effect of the intervention on BMI, but on waist circumference (-0.85; 95% confidence interval (95% CI) -1.59 to -0.12) and subscapular skinfold thickness (-0.64; 95% CI -1.25 to -0.02). After additional adjustment for individual time lag between baseline and follow-up, these effects were reduced to -0.60 (95% CI -1.25 to 0.05) and -0.61 (95% CI -1.26 to 0.04) and lost their statistical significance. CONCLUSION This study contributes to the field of randomised school-based studies on overweight prevention and shows that within a 1-year, integrated intervention no effect on BMI, but a tendency towards effects on fat mass can be achieved.

Abstract
Childhood overweight (body mass index (BMI)>90th centile) poses a major public health problem in so far as adult diseases manifest themselves already during childhood. In this review, after examining the prevalence of metabolic and cardiovascular diseases, the issue of whether BMI or other clinical parameters are valid tools to predict co-morbidities in children is discussed. Data of 2001-2008 are reviewed, including several studies conducted on more than 260,000 overweight and obese children in Germany and Switzerland. Apart from non-metabolic co-morbidities, namely musculoskeletal complications and attention deficit/hyperactivity disorders in up to 74% and up to 58% of overweight children, respectively, at least one cardiovascular and metabolic risk factor was seen in 52% of the overweight children, mostly high blood pressure (35%) with increased left ventricular mass or arterial stiffness. Signs of fatty liver disease or dyslipidemia were found in up to 29 and 32% of the children, respectively. Type 2 diabetes was found in less than 0.7% of the children, and an elevated fasting glucose or glucose intolerance in 3%. Irrespective of BMI, the quality of fat and protein intake predicted hypertension or insulin resistance, and fructose predicted lower (and more atherogenic) particle size of low-density lipoprotein-cholesterol. Out of the adiposity markers, waist circumference was closely correlated with insulin resistance and the components of the metabolic syndrome. In conclusion, risk factors are found in more than half of the overweight children, most frequently high blood pressure or dyslipidemia, and were mainly related to waist circumference, but also to BMI and fat mass. Even in the presence of normal BMI, screening for cardiovascular risk factors is advocated in each child with elevated waist circumference, but its cut-off points still remain to be validated. The increased occurrence of orthopedic and psychiatric complaints may detrimentally influence health-related lifestyle and obesity therapy.
