Background: The role of neuroendocrine alterations in the etiology of frailty syndrome is still poorly understood. Hypothalamic-pituitary-adrenal axis dysregulation is a plausible candidate pathway contributing to frailty. Thus, we sought to examine the associations of diurnal cortisol secretion with frailty in older adults. Methods: A cross-sectional analysis was conducted among 745 study participants (age 65–90 years, mean age 75.1 years) of the population-based KORA Age study. Associations between salivary cortisol measures at awakening (morning 1 [M1]), 30 minutes after awakening (M2), and evening (E) and frailty criteria were determined. Results: Lower cortisol levels in the first morning sample (M1) (P = .18) and M2 (P = .14) and increased E levels (P = .004) were observed in prefrail (35.17%, n = 262) and frail (3.36%, n = 25) individuals, in a dose-response manner. Frailty was strongly associated with smaller ratios of morning to evening levels; M1 to E ratio (P = .02) and M2 to E ratio (P = .003). Higher evening cortisol levels were associated with a 24% increased risk of a prefrail state (odds ratio, 1.22; 95% confidence interval, 1.03–1.44). A smaller morning to evening ratio was associated with an increased risk of low grip strength (1.42, 1.09–1.86) and gait speed (1.31, 1.02–1.68). Conclusion: Frailty status is associated with blunted cortisol reactivity as demonstrated by lower morning and higher evening salivary cortisol levels.

AbstractSarcopenia, similar to hypercortisolism, is characterized by loss of muscle mass and strength. Cortisol circadian rhythm changes with aging (blunted late-day nadir values) were suggested to contribute to this decline. We aimed to explore the relationship between diurnal salivary cortisol values and sarcopenia diagnosis and its components in postmenopausal women. This is a cross-sectional study within the OsteoLaus population-based cohort in Lausanne (Switzerland). Participants had a body composition assessment by dual X-ray absorptiometry (DXA), a grip strength (GS) measure, and salivary cortisol measures (at awakening, 30 min thereafter, 11 AM (sc-11AM) and 8 PM (sc-8PM)). Associations between salivary cortisol and sarcopenia diagnosed by six different criteria (based on appendicular lean mass (ALM) assessed by DXA, and muscle strength by GS), and its components, were analyzed. 471 women aged > 50 years (63.0 ± 7.5) were included. Various definitions identified different participants as sarcopenic, who consistently presented higher salivary cortisol at 11 AM and/or 8 PM. There were no associations between salivary cortisol levels and ALM measures, either absolute or after correction to height squared (ALM index) or body mass index. GS was inversely correlated to sc-11AM (r = − 0.153, p < 0.001) and sc-8PM (r = − 0.118, p = 0.002). Each 10 nmol/l increase of sc-11AM, respectively sc-8PM, was associated with a GS decrease of 1.758 (SE 0.472) kg, respectively 2.929 (SE 1.115) kg. In postmenopausal women, sarcopenia is associated with higher salivary cortisol levels at 11 AM and 8 PM. An increase of daily free cortisol levels in the physiological range could participate to sarcopenia development by decreasing muscle function in postmenopausal women.

AbstractBackgroundThe salivary circadian diurnal cortisol plays an important role in growth and development. Inappropriate levels may induce changes associated with an increased risk of obesity later in life. It is unknown if there are differences in cortisol secretion pattern between overweight/obese infants when compared with theirs peers in infancy. Thus, this study aimed to compare the salivary cortisol secretion pattern in overweight/obese and normal-weight infants.MethodsThirty-three (overweight/obese = 17 and normal weight = 16) infants between 6 and 24 months of age had saliva samples collected upon awakening (T1), 30 min after waking (T2), at 12:00 am or before the baby’s meal (T3), and prior to bedtime (T4). Highly sensitive enzyme immunoassays were used for cortisol analyses.ResultsSalivary cortisol levels were similar between the groups: T1 (p = 0.22; 95% confidence interval [CI]: −5.65, 1.37), T2 (p = 0.24; 95% CI: −8.23, 2.17), T3 (p = 0.95; 95% CI: −3.16, 2.96), and T4 (p = 0.81; 95% CI: −1.39, 1.08); and no differences were observed between area under the curve (AUC) (p = 0.80; 95% CI: −4.58–13.66). The cortisol level reduced in T4 (95% CI: 1.35–2.96) compared to T1 (95% CI: 5.15–8.49) and T2 in the overweight/obese group (p < 0.001; 95% CI: 6.02–11.04). In the normal-weight group, the cortisol reduced in T3 (95% CI: 2.86–8.18) compared to T1 (95% CI: 5.64–12.28) and decreased until T4 (p = 0.001; 95% CI: 1.25–3.37).ConclusionsThe overweight/obese infant group presented a different pattern of cortisol secretion, although cortisol levels did not differ between the control group.

Abstract Background Understanding the relationship between breastfeeding (BF) and metabolic syndrome (Mets) is important for maternal long-term health benefits and disease prevention. This study aimed to examine the association between BF and Mets and its components among postmenopausal parous Korean women. Methods This cross-sectional study on 10,356 Korean women used nationally representative data from the KNHANES from 2010 to 2016. Anthropometric, laboratory data and manual BP were measured. A multivariate logistic regression analysis was conducted to examine the association of BF with Mets and its components after adjusting for potential confounding variables. A p-value < 0.05 was to be considered statistically significant. Results Mets was present in 42% of the study participants. The BF group had low household income and education level. The prevalence of Mets in the BF group was higher than that in the non-BF group (42.69% vs. 34.76%, p <  0.001). BF was associated with increased risk of Mets (odds ratio [OR]: 1.4, 95% confidence interval [CI]: 1.18–1.65, p <  0.001). The BF group was at higher risks for diabetes (OR: 1.5, 95%CI: 1.14–1.98), hypertension (OR: 1.32, 95%CI: 1.03–1.68), hypertriglyceridemia (OR: 1.42, 95%CI: 1.02–1.99) and low high-density lipoprotein cholesterol (OR: 1.32, 95%CI: 1.06–1.65). Conclusion In this study, BF did not affect decreasing the prevalence of Mets and its components.

ABSTRACT Background The WHO currently recommends a daily sodium intake of 2 g and has established the goal of a 30% reduction in mean salt intake by 2025. Objective We sought to estimate sodium intake in study participants according to the locations of where they consumed meals and their demographic and socioeconomic characteristics and practices related to salt consumption. Methods A population-based, cross-sectional study was conducted with a sample of 2574 individuals aged ≥10 y who answered the 2015 Campinas-Brazil Nutrition Survey. Mean sodium intake was estimated using a 24-h recall log and associations with the independent variables were tested using generalized regression analysis stratified by age group. Results Sodium intake was higher in male participants as well as adolescents and adults who reported eating ≥1 meal outside the home (6.07% and 7.06% increase, respectively). Per meal, sodium was consumed more outside the home at breakfast, during an afternoon snack, and at dinner among adolescents. No significant differences were found in the analysis by type of meal among the adults and seniors. Conclusions Sodium intake exceeded the WHO recommendation in all age groups analyzed. Having ≥1 meal outside the home was associated with greater sodium intake among adolescents and adults. Measures to regulate the food industry and dietary/nutritional education strategies targeting consumers are important to reducing the sodium intake of the population.

Current data report that high levels of dental anxiety in children have a negative impact on oral health. The aim of this study was to measure dental anxiety, based on the Abeer Children Dental Anxiety Scale (ACDAS) used as a self-reported measure and to correlate its values with the salivary cortisol levels. The study was conducted in 2019 and included 389 children aged 6–9 years old; evaluation of dental anxiety and saliva sampling were performed. The influence of gender on the presence of dental anxiety was analyzed using Fisher’s exact test, the salivary cortisol level was compared between anxious and non-anxious children and was further correlated with the ACDAS score (p < 0.05). Girls had higher odds of experiencing dental anxiety (odds ratio: 1.533, p = 0.041). Salivary cortisol levels were higher in anxious compared to non-anxious children (median 1.251 vs. 1.091 ng/mL, p < 0.001) and showed a positive moderate correlation with the ACDAS score (r = 0.411, p < 0.001). Children aged 6–9 years have a high prevalence of dental anxiety, with girls being more susceptible to this condition. Salivary cortisol levels are higher in anxious children and correlate positively with the ACDAS score, proving that ACDAS can be used for the detection of dental anxiety.

Background. The epidemiology of atopic dermatitis (AD) in Chinese outpatients is yet to be clarified.Objectives. To investigate population-based prevalence and clinical features of AD in Chinese outpatients.Methods. A multicenter cross-sectional study was conducted in outpatients with eczema or dermatitis from 39 tertiary hospitals in 15 provinces.Results. This study included 682 patients diagnosed with AD, with the mean age of28.8±20.1years and the median course of5.3±6.9years. AD patients had more severe itching (30.4% versus 13.8%,p<0.001) and clinically suspected bacterial infection (21.7% versus 16.1%,p<0.001) than those of other types of dermatitis. Older patients were more susceptible to have a history of flexion dermatitis (p<0.001), bacterial infection (p=0.005), and severe itching (p<0.001). Outpatients with clinically suspected bacterial infection had 3.53-fold increased risk of AD than those without it (p<0.001). The morbidity rate of AD in the (20–25°N) region is 2.86 times higher than that in the (40–45°N) region [OR (95% CI): 0.352 (0.241–0.514),p<0.001].Conclusions. AD is characterized by unique clinical/demographic features. Bacterial infection and latitude region may have an impact on the incidence of AD in China.

Background: The presentation of minor head trauma warrants immediate and accurate diagnosis for early clinical management among children. Computed Tomography is the gold standard tool for the diagnosis of Traumatic Brain Injury (TBI) among the children. The timing of presentation may have a significant role in predicting the incidence of TBI. This study was done to compare the CT findings among children who presented within and after 24 hours with minor head trauma.Methods: This cross-sectional study was carried out among 992 children between 2-15 years reporting with a history of head injury. All the participants were clinically examined, and relevant history of type of injury and timing of presentation was recorded. CT scan was taken as per PECARN criteria. Data was entered and analysed using SPSS ver 15 software.Results: Majority of the participants belonged to 6-10 years of age (45.2%) and were males (58.5%). About 81.7% of the participants presented within 24 hours. The overall prevalence of TBI among the study participants was 58.6% [55.5-61.6].It was observed that hematoma predominantly presented after 24 hours (74.2%) and majority of the falls presented after 24 hours (92.8%).Patients who presented after 24 hours were at increased risk of presenting as TBI (67.03%) compared to those presenting within 24 hours (56.8%;p<0.05).Conclusions: This study has emphasized the need for including the timing of presentation as a key factor for facilitating early diagnosis and rapid case management of pediatric head trauma.

Abstract Background: The hypertriglyceridemic waist (HTGW) phenotype has been suggested as a risk factor for chronic kidney disease (CKD), but evidence on relationship of triglyceride waist phenotypes with estimated glomerular filtration rate (eGFR) status and severity is limited. Our aim was to explore the association of triglyceride waist phenotypes with reduced eGFR and various decreased eGFR stages among Chinese adults.Methods: A population-based, cross-sectional study was conducted among Chinese participants aged 20-74 years during June 2016 to December 2017 in Shanghai, China. An eGFR value below 60 mL/min/1.73 m2 was defined as Decreased eGFR. The HTGW phenotype was defined as a triglycerides (TG) level ≥1.7 mmol/L and a waist circumference (WC) ≥90 cm for men and ≥80 cm for women. We examined the association of triglyceride waist phenotypes with decreased eGFR risk using the weighted logistic regression models.Results: A total of 31,296 adults were included in this study. Compared with normal TG level/normal WC (NTNW) phenotype, normal TG level/enlarged WC (NTGW), elevated TG level/normal WC (HTNW), elevated TG level/enlarged WC (HTGW) were associated with the increased risk of decreased eGFR, with an multivariable-adjusted ORs (95% CI) of 1.77 (1.42-2.20), 1.48 (1.16-1.90), and 2.30 (1.80-2.93), respectively. These positive associations between triglyceride waist phenotypes and decreased eGFR risk remained across almost all the subgroups, including sex, age, BMI, T2DM, and hypertension. NTGW, HTNW, and HTGW phenotype were consistently positively associated with the risk of mildly and moderately decreased eGFR, but not with severely decreased eGFR risk.Conclusions: HTGW was consistently associated with the increased risk of decreased eGFR and various decreased eGFR stages except for severely decreased eGFR. The findings imply that HTGW may be an important risk factor for renal dysfunction or an indicator for prevention and control aiming to reduce renal function decline.

Abstract Anemia is a global public health problem affecting women worldwide, and reproductive-age women are at increased risk. We conducted a population-based cross-sectional study analyzing the prevalence of overall anemia and anemia according to severity in Chinese pre-pregnant women to update current knowledge on anemia epidemiology. Based on the National Free Preconception Check-up Projects supported by the Chinese government, 5,679,782 women participating in this project in 2017 were included in this study. The cyanmethemoglobin method was applied to assess hemoglobin concentrations. Univariate and multivariate logistic regressions were applied for associated factors. The prevalence of anemia among Chinese pre-pregnant women was 21.64% (mild anemia: 14.10%, moderate anemia: 7.17%, severe anemia: 0.37%). The prevalence of overall and severe anemia was the highest in Tibet and the lowest in Beijing among 31 provinces. Women’s age, region, ethnic origin, educational level, occupation, and pregnancy history were all correlated with anemia. Women with B blood type (aOR=0.89), higher BMIs (overweight: aOR=0.84; obesity: aOR=0.70), and alcohol consumption (aOR=0.69) were less likely to have anemia, while those with rhesus negative blood type (aOR=1.10), history of anemia (aOR=2.60), older age at menarche (aOR=1.19), heavy menstrual blood loss (aOR=1.39), longer menstrual period (aOR=1.09) and shorter menstrual cycle (aOR=1.08) were more likely to suffer from anemia. Meat or egg eaters were not significantly associated with severe anemia. Anemia is of moderate public health significance among Chinese pre-pregnant women. Interventions should be considered to prevent anemia to the greatest extent possible to avoid potential harm in this population.
