Do fit kids have fit parents?

BACKGROUND: Physical fitness is an important indicator of current and future health status. This analysis examines the relationships among child-parent dyads in physical fitness measures. DATA AND METHODS: The analysis is based on biological child-parent dyads from three cycles of the Canadian Health Measures Survey (Cycle 1: 2007 to 2009, Cycle 2: 2009 to 2011, and Cycle 5: 2016 to 2017). Physical fitness components-cardiorespiratory (CRF) (n = 615), muscular strength (n = 1,319) and flexibility (n = 1,295)-were measured at mobile examination centres using standardized fitness tests. Descriptive, correlation and regression analyses were used to examine relationships among child-parent dyads. RESULTS: CRF (R = 0.12), muscular strength (R = 0.23) and flexibility (R = 0.22) measures were weakly correlated among child-parent dyads. Modest increases in the physical fitness levels of children were observed with increases in the fitness rating scores of their parents. According to unadjusted and adjusted regression models, CRF (p< 0.05), muscular strength (p< 0.001) and flexibility (p< 0.001) were positively associated among child-parent dyads. When examined by sex of parent and child, CRF was significantly associated in mother-son dyads only, grip strength was associated in all dyad types except father-son pairings, and flexibility was associated in mother-son and father-son pairings only. DISCUSSION: A significant and positive association was evident in measured physical fitness among parents and children. Some variation in the presence and strength of associations existed according to child and parent sex.

Trends in physical fitness among Canadian adults, 2007 to 2017.

BACKGROUND: The fitness levels of Canadian adults declined substantially between 1981 and the years 2007 to 2009, suggesting a reduction in population health. This paper updates the fitness trends of Canadians aged 20 to 69 years by extending the time period to 2017. DATA AND METHODS: The Canadian Health Measures Survey is a repeated cross-sectional survey that is conducted to produce nationally representative health estimates. Descriptive statistics are presented for fitness measures in 2016 and 2017 by age and sex, and trends in fitness were calculated spanning a period of 10 years (2007 to 2017). The associations between fitness measures and meeting the 2020 Canadian physical activity recommendations were also assessed. RESULTS: From 2007 to 2017, there were few statistically significant changes in the fitness levels of Canadian adults. When all ages were combined, there were declining trends in predicted cardiorespiratory fitness, from 39.5 to 36.7 mL•kg⁻¹â€¢min⁻¹ among men and 34.0 to 32.2 mL•kg⁻¹â€¢min⁻¹ among women. Trends indicated declining flexibility among men. In general, meeting the current Canadian moderate-to-vigorous physical activity recommendation was associated with better fitness, particularly in the categories of predicted cardiorespiratory fitness and body composition. INTERPRETATION: The periodic assessment of fitness in Canadians provides valuable insight into population health. The present update provides evidence that fitness levels among adults have generally stabilized over the past 10 years. Taken with the reported declines in fitness that occurred from 1981 to the 2007-to-2009 period, this study shows that the fitness of Canadian adults remained low between 2007 to 2009 and 2016 to 2017. It is necessary to explore new ways to help improve the fitness levels of the Canadian population.

Trends in physical fitness among Canadian children and youth.

BACKGROUND: Physical fitness during childhood is an important indicator of current and future health. This paper provides an overview of the fitness of Canadian children and youth aged 6 to 19 years. DATA AND METHODS: Data are from three cycles of the Canadian Health Measures Survey (CHMS) spanning a 10-year period: 2007 to 2009 (n = 2,081), 2009 to 2011 (n = 2,133) and 2016 to 2017 (n = 2,070). The CHMS is a comprehensive direct health measures survey conducted on a nationally representative sample of Canadians. Descriptive statistics for measures of cardiorespiratory fitness, muscular strength and power, flexibility, and body composition are provided by age group and sex. Physical fitness measures are presented for participants who met and did not meet the physical activity and screen time recommendations. RESULTS: Few changes in the fitness measures occurred over the past decade. Cardiorespiratory fitness decreased between 2007-2009 and 2016-2017 in 8 to 10 (52.1 to. 51.0 mL•kg-1•min-1) and 11 to 14 (50.8 to 49.8 mL•kg-1•min-1) year old boys. Girls generally had lower levels of fitness compared to boys, except for flexibility which was higher in girls. Cardiorespiratory fitness was higher in children and youth who met the current Canadian recommendations for physical activity and screen time. Grip strength was higher in boys who met the current Canadian screen time recommendation. DISCUSSION: Ongoing and periodic surveillance of fitness through the CHMS is important to monitor trends, assess future interventions designed to improve fitness levels at the population level and to increase our understanding of the relationships between fitness and health.

Normative-referenced percentile values for physical fitness among Canadians.

BACKGROUND: This study developed age- and sex-specific normative-referenced percentile values for five physical fitness tests across a wide age range of Canadians, using a nationally representative sample. DATA AND METHODS: The data are from 5,188 Canadians (50.1% female) and were collected as part of cycle 5 of the Canadian Health Measures Survey (2016 to 2017). RESULTS: Males had slightly better cardiorespiratory fitness and substantially better grip strength, jumping height and jumping power scores than females, whereas females had better sit-and-reach flexibility. Among females, there were pronounced increases in jumping height (P50: 25%) and jumping power (P50: 58%) between ages 8 and 13, and in grip strength (P50: 193%) between ages 6 and 19. Performance gradually declined with age, beginning in adolescence for jumping ability and at approximately age 35 for grip strength. Among males, there were pronounced increases in jumping height (P50: 69%) and jumping power (P50: 233%) between ages 8 and 20, and in grip strength (P50: 365%) between ages 6 and 20. Performance gradually declined with age, beginning immediately after adolescence for jumping ability and at approximately age 30 for grip strength. Sit-and-reach flexibility remained relatively stable with age in both sexes. Cardiorespiratory fitness scores in both sexes declined steadily with age beginning (generally) at age 8, with a larger decline evident in females until age 18. DISCUSSION: These normative-referenced values for physical fitness could be useful for screening in public health and clinical practice.

Yogurt consumption, body composition, and metabolic health in the Québec Family Study.

PURPOSE: The aim was to compare the anthropometric and metabolic profiles and lifestyle behaviours of yogurt consumers and non-consumers and to determine if the observed differences persisted after adjustment for diet quality and related variables. METHODS: Using cross-sectional and follow-up data from the Québec Family Study, men and women were classified into yogurt consumers (n = 269; 96 men and 173 women) and non-consumers (n = 570; 279 men and 291 women), and their anthropometric measurements, metabolic profiles, and lifestyle factors were compared. RESULTS: Men yogurt consumers had a lower body weight, BMI, % body fat, waist circumference and lower plasma insulin, and C-peptide concentrations in response to oral glucose, while women yogurt consumers had lower waist circumference, BMI, % body fat, plasma glucose, insulin, and C-peptide compared with non-consumers (P < 0.05). After adjustment for the Nutrient-Rich Foods (NRF) index, a marker of diet quality, these differences persisted in men and only for glycemic variables in women. Additional adjustment for physical activity participation and % body fat did not abolish the significant differences observed between yogurt consumers and non-consumers for plasma glucose, insulin, and C-peptide responses to oral glucose in women only (P < 0.05). Analyses of data after a 6-year follow-up reinforced these observations, since both men and women yogurt consumers maintained a better metabolic profile compared with non-consumers after adjustments for age and NRF (P < 0.05). In addition, an interaction between group and time for % body fat in men suggests a benefit of yogurt consumption over time on body composition. CONCLUSION: Yogurt consumption is associated with body composition and metabolic health benefits that are not entirely explained by a global effect of diet quality.

Global Epidemiology of Hip Fractures: Secular Trends in Incidence Rate, Post-Fracture Treatment, and All-Cause Mortality.

In this international study, we examined the incidence of hip fractures, postfracture treatment, and all-cause mortality following hip fractures, based on demographics, geography, and calendar year. We used patient-level healthcare data from 19 countries and regions to identify patients aged 50 years and older hospitalized with a hip fracture from 2005 to 2018. The age- and sex-standardized incidence rates of hip fractures, post-hip fracture treatment (defined as the proportion of patients receiving anti-osteoporosis medication with various mechanisms of action [bisphosphonates, denosumab, raloxifene, strontium ranelate, or teriparatide] following a hip fracture), and the all-cause mortality rates after hip fractures were estimated using a standardized protocol and common data model. The number of hip fractures in 2050 was projected based on trends in the incidence and estimated future population demographics. In total, 4,115,046 hip fractures were identified from 20 databases. The reported age- and sex-standardized incidence rates of hip fractures ranged from 95.1 (95% confidence interval [CI] 94.8-95.4) in Brazil to 315.9 (95% CI 314.0-317.7) in Denmark per 100,000 population. Incidence rates decreased over the study period in most countries; however, the estimated total annual number of hip fractures nearly doubled from 2018 to 2050. Within 1 year following a hip fracture, post-hip fracture treatment ranged from 11.5% (95% CI 11.1% to 11.9%) in Germany to 50.3% (95% CI 50.0% to 50.7%) in the United Kingdom, and all-cause mortality rates ranged from 14.4% (95% CI 14.0% to 14.8%) in Singapore to 28.3% (95% CI 28.0% to 28.6%) in the United Kingdom. Males had lower use of anti-osteoporosis medication than females, higher rates of all-cause mortality, and a larger increase in the projected number of hip fractures by 2050. Substantial variations exist in the global epidemiology of hip fractures and postfracture outcomes. Our findings inform possible actions to reduce the projected public health burden of osteoporotic fractures among the aging population. © 2023 The Authors.

Global epidemiology of hip fractures: a study protocol using a common analytical platform among multiple countries.

INTRODUCTION: Hip fractures are associated with a high burden of morbidity and mortality. Globally, there is wide variation in the incidence of hip fracture in people aged 50 years and older. Longitudinal and cross-geographical comparisons of health data can provide insights on aetiology, risk factors, and healthcare practices. However, systematic reviews of studies that use different methods and study periods do not permit direct comparison across geographical regions. Thus, the objective of this study is to investigate global secular trends in hip fracture incidence, mortality and use of postfracture pharmacological treatment across Asia, Oceania, North and South America, and Western and Northern Europe using a unified methodology applied to health records. METHODS AND ANALYSIS: This retrospective cohort study will use a common protocol and an analytical common data model approach to examine incidence of hip fracture across population-based databases in different geographical regions and healthcare settings. The study period will be from 2005 to 2018 subject to data availability in study sites. Patients aged 50 years and older and hospitalised due to hip fracture during the study period will be included. The primary outcome will be expressed as the annual incidence of hip fracture. Secondary outcomes will be the pharmacological treatment rate and mortality within 12 months following initial hip fracture by year. For the primary outcome, crude and standardised incidence of hip fracture will be reported. Linear regression will be used to test for time trends in the annual incidence. For secondary outcomes, the crude mortality and standardised mortality incidence will be reported. ETHICS AND DISSEMINATION: Each participating site will follow the relevant local ethics and regulatory frameworks for study approval. The results of the study will be submitted for peer-reviewed scientific publications and presented at scientific conferences.

Acute effects of protein composition and fibre enrichment of yogurt consumed as snacks on appetite sensations and subsequent ad libitum energy intake in healthy men.

The objective of the study was to assess the impact of protein composition and/or fibre enrichment of yogurt on appetite sensations and subsequent energy intake. In this double-blind crossover study, 20 healthy men (aged 32.4 ± 9.1 years) were submitted to 5 randomized testing sessions, during which they had to consume 5 isocaloric and isonproteinemic yogurt snacks (120-g servings, ∼230 kJ, ∼4.5 g protein) differing by their casein-to-whey protein ratio (C:W) or dietary fibre content: (i) control C:W = 2.8:1; (ii) high whey (HW) C:W = 1.5:1, and fibre-enriched formulations using control; (iii) 2.4 g of inulin; (iv) 1.9 g of inulin and 0.5 g of ß-glucan (+IN-ßG); and (v) 0.5 g of ß-glucan. Appetite sensations were assessed using 150-mm visual analog scales. Plasma variables (glucose, insulin, ghrelin) were measured at 30-min intervals post-yogurt consumption for 2 h. Finally, energy intakes during ad libitum lunches offered 2 h after yogurt snacks were recorded. None of the yogurts impacted appetite sensations. Ad libitum energy intake was significantly different only between HW and control yogurts (-812 kJ; p = 0.03). Regarding post-yogurt plasma variables, a significant difference was found only between ghrelin area under the curve of the +IN-ßG and the HW yogurts (-15 510 pmol/L per 120 min, p = 0.04). In conclusion, although appetite sensations were not influenced by variations in yogurts' protein compositions, a reduced energy intake was observed during the ad libitum lunch after the HW yogurt that may be attributable to its lower C:W. Surprisingly, the fibre enrichments studied did not exert effect on appetite sensations and energy intake.

Association between Abdominal Fat (DXA) and Its Subcomponents (CT Scan) before and after Weight Loss in Obese Postmenopausal Women: A MONET Study.

Introduction. Subcutaneous fat (ScF) and visceral fat (VF) measurements using CT scan are expensive and may imply significant radiation doses. Cross-sectional studies using CT scan showed that ScF and VF are significantly correlated with abdominal fat measured by DXA (AF-DXA). The association has not been studied after a weight loss. Objective. To determine (1) the associations between AF-DXA and ScF and VF before and after weight loss and (2) the associations between their changes. Methods. 137 overweight/obese postmenopausal women were divided in two groups (1-caloric restriction or 2-caloric restriction + resistance training). AF was assessed using DXA and CT scan. Results. Correlations between AF-DXA and ScF (before: r = 0.87, after; r = 0.87; P < .01) and, AF-DXA and VF (before: r = 0.61, after; r = 0.69; P < .01) are not different before and after the weight loss. Correlations between delta AF-DXA and delta ScF (r = 0.72; P < .01) or delta VF (r = 0.51; P < .01) were found. Conclusion. The use of AF-DXA as a surrogate for VF after weight loss is questionable, but may be interesting for ScF.
