AbstractObjectiveTo assess the association of time spent viewing television, videos and video games with measures of fat mass (BMI) and distribution (triceps and subscapular skinfold thicknesses (TSF, SSF)).DesignCross-sectional validated survey, self-administered to students to assess screen time (television, videos and video games) and lifestyle variables. Trained personnel obtained anthropometry. The association of screen time with fat mass and distribution, stratified by sex, was modelled with multivariable linear regression analysis, adjusting for potential confounders and correlation of observations within schools.SettingState of Morelos, Mexico.SubjectsMales (n 3519) and females (n 5613) aged 11 to 18 years attending urban and rural schools in Morelos.ResultsIn males, screen time of >5 h/d compared with <2 h/d was significantly associated with a 0·13 (95 % CI 0·04, 0·23) higher BMI Z-score, 0·73 mm (95 % CI 0·24, 1·22) higher SSF and 1·08 mm (95 % CI 0·36, 1·81) higher TSF. The positive association of screen time with SSF was strongest in males aged 11–12 years. Sexual maturity appeared to modify the association in females; a positive association between screen time and SSF was observed in those who had not undergone menarche (P for trend = 0·04) but not among sexually mature females (P for trend = 0·75).ConclusionScreen time is associated with fat mass and distribution among adolescent males in Mexico. Maturational tempo appears to affect the relationship of screen time with adiposity in boys and girls. Findings suggest that obesity preventive interventions in the Mexican context should explore strategies to reduce screen time among youths in early adolescence.

Nature Experience

History is replete with examples where humans have sought refuge in nature for psychological restoration. In this cross-sectional study we explore the relationship of nature experience and mindfulness. Nature experience is assessed through “nature in the neighbourhood”, “frequency of visit” to nature-rich spaces, as well as one's inherent connection with nature described as “nature relatedness”. The study sample consisted of 334 Indian adults. The findings from this study show that frequency of visit to nature-rich spaces has a significant positive association with mindfulness. The hierarchical regression analysis suggests an interaction effect of “nature relatedness” in the association of the presence of nature rich spaces in the neighbourhood, frequency of visit as well as mindfulness. Interestingly, when childhood experiences were explored they had a significant association with “nature relatedness” and mindfulness. The evidence from this research suggests that nature experience may find its application as one of the mindfulness techniques prescribed for self-management of mental health problems.

Abstract Background: To investigate the relationship between corneal astigmatism and age, axial length (AL) among Chinese over fifty years old. Methods: This study enrolled 1,082 right eyes of age-related cataract patients over 50 years old in the clinic of Peking University People’s Hospital, Beijing, China. Axial length, magnitude and meridian of anterior corneal astigmatism were measured by IOLMaster. Restricted cubic splines and Spearman rank correlation coefficients were used to investigate the relationship of the magnitude of cornea astigmatism to age and AL. Power vector analysis method and linear regression analysis were used to assess the relationship of the meridian of astigmatism to age and AL. Results: For this study , mean age, AL, and corneal astigmatism value were 72.45 ±9.28 years, 23.90±1.93mm, and 1.12±0.74D, respectively. The magnitude of corneal astigmatism was 0.75D or higher in 63.8% eyes. The magnitude of corneal astigmatism increased with age after 65 years old. This correlation was statistically significant when AL was between 22.00mm and 26.00mm. The vector value in J 0 was inversely correlated with age. The mean vector value change from with-the-rule (WTR) to against-the-rule (ATR) corneal astigmatism was 0.22D/10 years during 50-65 years old and 0.15D/10 years during 65-85 years old, and was 0.22D/10 years in male and 0.12D/10 years in female, respectively. Conclusions: A large proportion of elderly Chinese cataract patients over 50 years old have corneal astigmatism more than 0.75D . There was a non-linear trend from WTR astigmatism towards ATR astigmatism with age, which was more obvious in elder age and in male. When AL is between 22.00mm and 26.00mm, the magnitude of corneal astigmatism increases with age after 65 years old.

Introduction: The purpose of this study was to investigate the detailed nature of menstrual characteristics, bleeding and other symptoms in women with and without endometriosis. Pelvic pain symptoms in this cohort have been reported elsewhere. Method: This is a self-administered cross-sectional study and was conducted using a structural questionnaire. A total of 737 women completed the study: women with endometriosis (n = 529) and with no current gynaecological complaint, ‘control’ (n = 208). Results: Some of the key findings in this study included significant differences between the control and endometriosis subjects in terms of bleeding symptoms, increased length and heaviness of menses, rectal and bladder bleeding, infertility and obstetric complications which were all more common in the endometriosis group. Other symptoms found to have a highly significant positive association with endometriosis included abdominal bloating, low resistance to infection, fatigue, increased urinary frequency, diarrhoea and constipation (p < 0.000). Data were cross-tabulated to examine the association of a number of symptoms to each other. The relationship of symptoms to a range of psychosocial factors was investigated to determine how the effects of endometriosis impacted on the life of subjects. Most women reported that endometriosis sometimes or often interfered with daily aspects of their life. Conclusion: The range of non-pain symptoms in women with endometriosis was generally much more diverse and extensive than recognised by most clinicians.

AbstractSubjects with high fibroblast growth factor 21(FGF21) and 23 (FGF23), endocrine hormones that regulate insulin sensitivity and phosphate metabolism, respectively, are reported to have a higher risk for adverse cardiovascular outcome. Therefore, the relationship of FGF21, FGF23, and α-Klotho (co-receptor for FGF23 signaling) with mean platelet volume (MPV) and platelet distribution width (PDW), two platelet volume indices that reflect platelet activity, was investigated.Data from 156 patients admitted to the cardiology department were analyzed. MPV and PDW were measured by an automatic blood counter, and serum FGF21, FGF23, and α-Klotho concentrations were measured by an enzyme-linked immunoassay.Log(FGF21) was significantly correlated with serum triglycerides but did not differ according to the use of non-use of antidiabetic or lipid-lowering drugs. MPV and PDW were significantly correlated (R=0.475, p<0.001). MPV was significantly correlated with log(FGF21) (R=–0.167, p<0.05) and log(FGF23) (R=0.351, p<0.001) but not with log(α-Klotho). Linear regression analysis showed a negative and positive association of log(FGF21) and log(FGF23), respectively, with MPV that was independent of possible confounders including sex, age, renal function, and antithrombotic drug use. In addition, log(FGF23) was found to have a significant independent positive association with PDW.Among cardiac patients, FGF21 had a negative association with MPV, whereas FGF23 had a positive association. Future studies of serum FGF23/FGF21 concentrations and the incidence of thromboembolic disorders are warranted.

Background: Studies have reported the association between cardiorespiratory fitness and higher adherence to the Mediterranean diet as well as lower recreational screen time. Similarly, higher screen time has been negatively linked to a lower adherence to the Mediterranean diet. However, the mediator effect of cardiorespiratory fitness on the influence of screen time on adherence to the Mediterranean diet is still unknown. The aim of this study was two-fold: first, to assess the combined association of recreational screen time and cardiorespiratory fitness with adherence to Mediterranean diet among Spanish schoolchildren, and second, to elucidate whether the association between recreational screen time and adherence to the Mediterranean diet is mediated by cardiorespiratory fitness. Methods: A descriptive and cross-sectional study was conducted. A total of 370 schoolchildren aged 6–13 years from six schools in the Region of Murcia (Spain) were included. Results: The mediation analysis showed that once screen time and cardiorespiratory fitness were included together in the model, cardiorespiratory fitness was positively linked to adherence to the Mediterranean diet (p = 0.020) and although screen time remained negatively related to adherence to the Mediterranean diet, this association was slightly attenuated (indirect effect = −0.027; 95% CI = (−0.080, −0.002)). Conclusions: This research supports that cardiorespiratory fitness may reduce the negative association between screen time and Mediterranean dietary patterns.

Objective: This study is a meta-analysis that considers the association between dyadic coping and emotional functioning, and between dyadic coping and the quality of the relationship as perceived by cancer patients and their life partners.Methods: A systematic search was conducted in the electronic databases PsycINFO, PubMed, ScienceDirect and those peer-reviewed cross-sectional and longitudinal studies published up until April 2020 that investigated these relationships were selected.Results: A total of 1,168 studies were identified, of which 10 met the inclusion criteria (N = 1,727 couples). These evidenced statistically significant positive relationships between common dyadic coping and emotional functioning and between common dyadic coping and the quality of the relationship as perceived by patients and their partners. There was also a statistically significant positive association between stress communication (by oneself), supportive dyadic coping (by oneself and by partner), and the quality of the relationship. In addition, a statistically significant negative association was found between negative dyadic coping (by oneself and by partner) and the quality of the relationship as perceived by patients' partners and also between negative dyadic coping (by oneself) and the quality of the relationship as perceived by patients.Conclusions: The results suggest the existence of a significant association between dyadic coping and emotional functioning and between dyadic coping and the quality of the relationship as perceived by members of couples facing cancer. However, these results must be interpreted with caution due to the small number of studies included in the analysis. Clinically, an understanding of the existence of such relationships is helpful for the implementation, and study of the effectiveness of, interventions aimed at improving dyadic coping in order to improve both quality of life and quality of relationship in couples where there is an oncological diagnosis.
