AbstractRhotics, particularly the trill, are late acquired sounds in Spanish. Reports of Spanish–English bilingual preschoolers document age-appropriate articulations, but studies do not explore productions once exposure to English increases. This paper reports on the rhotic productions of a cross-sectional sample of 31 Spanish–English bilingual children, ages 6;8 to 13;5. Children produced taps with high rates of accuracy across age groups; the trill did not reach 80% target production until age 11;3, later than reported for monolingual speakers. Increased English exposure is explored as a contributing factor, arguing a need for continued study of bilingual phonological development beyond the preschool years.

Aim. To study the prevalence of hypotension according to several criteria in the Russia and the USA.Material and methods. We used data of Russian population studies performed in 1975-1982 and ESSE-RF study performed in 2012-2014 at the National Medical Research Center for Therapy and Preventive Medicine. A comparison was made with the data of cross-sectional stu - dies of the US population — National Health and Nutrition Examination Survey (NHANES): NHANES II (1976-1980) and Continuous NHANES (2007-2012). We analyzed age, sex, and systolic and diastolic blood pressure. The prevalence of individuals with hypotension was calculated in men and women of five age groups using four different criteria for hypertension.Results. The prevalence of hypotension in studies of different years according to different criteria was as follows: in the Russia — 0,3-9,0% in men and 2-15% in women; in the USA — 5-30% in men and 8-45% in women. In age group >30 years, the prevalence of hypotension in Russia, by most criteria, decreased approximately by 50% in men and did not change in women. In the United States, according to all criteria, the prevalence in men and women has increased 2-3 times.Conclusion. The prevalence of hypotension in the adult population ranges from decimal percentages to 45% and varies many times depending on the selected criterion.

The purpose of this cross-sectional, exploratory analysis was to describe age-related patterns of blood pressure (BP) among participants in India (using the 2014 Annual Health Survey) and the United States (using National Health & Nutrition Examination Surveys 2011-2016). We included 10,759 U.S. and 790,641 Indian participants aged ≥20 years with ≥2 BP readings. We plotted mean systolic (SBP) and diastolic BP (DBP) across 5-year age groups and estimated best fit models. SBP increased linearly with age in both sexes and study populations (R 2 : 0.88-0.99; Fig. 1-2). Those with overweight/obese BMI had higher SBP and modestly higher rates of increase in SBP. DBP followed a quadratic curve (R 2 : 0.68-0.99), peaking in the 5-6th decade (45-49 years in U.S. and 50-59 in India) with higher and earlier peaks in those with elevated BMI. The models’ strong fit and similarity between study populations supports the notion that physical processes underly BP’s age-related changes.

The authors examined if body mass index (BMI), weight, and height across age groups differ between adults with Down syndrome (DS) and adults with intellectual disability but without DS. They conducted secondary analyses of cross-sectional data from 45,803 individuals from the United States from 2009 to 2014 of the National Core Indicators Adult Consumer Survey across five age groups: 18–29, 30–39, 40–49, 50–59, and 60+ years. For both men and women with DS, BMI and weight increased between the 18- to 29- and the 30- to 39-year age groups and decreased thereafter. For both men and women with intellectual disability, BMI and weight increased between the 18- to 29- and the 30- to 39-year age groups, stayed about the same until the 50- to 59-year age group, and decreased thereafter. Height demonstrated a small but significant decrease with older age in all groups. These cross-sectional comparisons indicate that BMI and weight may start decreasing at a younger age in adults with DS than in adults with intellectual disability.

Objectives: Characterization of the epidemiology and cost of lawn-mower injuries is potentially useful to inform injury prevention and health policy efforts. We examined the incidence, distribution, types and severity, and emergency department (ED) and hospitalization charges of lawn-mower injuries among all age groups across the United States. Methods: This retrospective, cross-sectional study used nationally representative, population-based (all-payer) data from the US Nationwide Emergency Department Sample for lawn-mower–related ED visits and hospitalizations from January 1, 2006, through December 31, 2013. Lawn-mower injuries were identified by using International Classification of Diseases, Ninth Revision, Clinical Modification code E920 (accidents caused by a powered lawn mower). We analyzed data on demographic characteristics, age, geographic distribution, type of injury, injury severity, and hospital charges. Results: We calculated a weighted estimate of 51 151 lawn-mower injuries during the 8-year study period. The most common types of injuries were lacerations (n = 23 907, 46.7%), fractures (n = 11 433, 22.4%), and amputations (n = 11 013, 21.5%). The most common injury locations were wrist or hand (n = 33 477, 65.4%) and foot or toe (n = 10 122, 19.8%). Mean ED charges were $2482 per patient, and mean inpatient charges were $36 987 per patient. The most common procedures performed were wound irrigation or debridement (n = 1436, 29.9%) and amputation (n = 1230, 25.6%). Conclusions: Lawn-mower injuries occurred at a constant rate during the study period. Changes to nationwide industry safety standards are needed to reduce the frequency and severity of these preventable injuries.

This paper describes normative data for newly collected exemplar responses to 70 semantic categories described in previous norming studies (Battig & Montague, 1969; Van Overschelde, Rawson, & Dunlosky, 2004; Yoon et al., 2004). These categories were presented to 246 Young (18 – 39 years), Middle (40 – 59 years), and Older (60 years and older) English-speaking adults living in the United States who were asked to generate as many category exemplars as possible for each of the 70 categories. In order to understand differences in normative responses, we analyzed these responses a) between age groups within the current sample and b) in comparison to three previously-published sets of norms. Experimental studies using such norms typically assume invariance of normative likelihoods across age and historical time. We replicate previous findings such that exemplar frequency correlations suggest moderate stability in generated category members between age groups and cohorts for many, but not all, categories. Further, analyses of rank order correlations highlight that the traditional measure of typicality may not capture all aspects of typicality, namely that for some categories there is high consistency in the frequency of exemplars across age groups and/or norms, but the ordering of those exemplars differs significantly. We include a cluster analysis to aid in grouping categories based on relative stability across time, cohort, and age groups. These results emphasize the importance of maintaining and updating age-differentiated category norms.

Heart rate (HR) acceleration is one of the risk factors of the number of prevalent chronic non-communicable diseases.Aim. To evaluate changes in mean levels of HR in the Russian Federation (RF) and the United States of America (USA) in different age and sex groups from 1975 to 2014.Material and methods. HR levels in men and women of different age groups were evaluated in the populations of the RF and the USA in 1975-1982 and in 2007-2014 by the secondary analysis of cross-sectional trials data. A total number of cases was 48974.Results. In 80th years of XX century Russian men and women of all age groups had lower HR as compared to the USA, the distinctions were statistically significant in all age groups except for men aged 25-34 years (p<0.0001). During the next 3 decades HR significantly decreased in all groups of the USA population, while the RF population demonstrated variety of HR levels trends in different groups, absolute distinctions in mean values were relatively small and did not exceed 2 beats per minute. At the present time HR levels are less in the RF as compared to the USA in women aged 25-55 years and in men aged 25-34 years; in 55-64-year old men HR is somewhat higher in the RF than in the USA, other groups revealed statistically insignificant distinctions.Conclusion. The USA evidently loosed out to the RF in mean levels of HR in all age groups 35 years earlier. During the next 3 decades situation has been worsened as applied to the RF and distinctions with the USA have been largely smoothed over.

Abstract Background Benign meningiomas are the most frequently reported central nervous system tumors in the United States (US), with increasing incidence in past decades. However, the future trajectory of this neoplasm remains unclear. Methods We analyzed benign meningioma incidence of cases identified by any means (eg, radiographically with or without microscopic confirmation) in US Surveillance Epidemiology and End Results (SEER) cancer registries among 35–84-year-olds during 2004–2017 by sex and race/ethnicity using age-period-cohort (APC) models. We employed APC forecasting models to glean insights regarding the etiology, distribution, and anticipated future (2018–2027) public health impact of this neoplasm. Results In all groups, meningioma incidence overall increased through 2010, then stabilized. Temporal declines were statistically significant overall and in most groups. JoinPoint analysis of cohort rate-ratios identified substantial acceleration in White men born after 1963 (from 1.1% to 3.2% per birth year); cohort rate-ratios were stable or increasing in all groups and all birth cohorts. We forecast that meningioma incidence through 2027 will remain stable or decrease among 55–84-year-olds but remain similar to current levels among 35–54-year-olds. Total meningioma burden in 2027 is expected to be approximately 30,470 cases, similar to the expected case count of 27,830 in 2018. Conclusions Between 2004–2017, overall incidence of benign meningioma increased and then stabilized or declined. For 2018–2027, our forecast is incidence will remain generally stable in younger age groups but decrease in older age groups. Nonetheless, the total future burden will remain similar to current levels because the population is aging.

AbstractAttention-deficit hyperactivity disorder (ADHD) is an increasingly recognized chronic neurodevelopmental disorder. This work aims at studying the prevalence and clinical characteristics of children with ADHD in the United States in the period between 2009 and 2018. Data from the National Health Interview Survey were analyzed by univariate and multivariate statistics to assess the role of socioeconomic factors in the development of ADHD. It has been studied 615,608 children, 51.2% male and 48.7% female. The prevalence of ADHD was 9.13%, with males predominating over females. The number of children with ADHD increased from 2009 to 2018 by 14.8%. As specified by multiple logistic regression analysis, males (odds ratio [OR] 2.38) who have neither mother nor father (OR 1.76) are twice as likely to have ADHD compared with their peers. In addition, family income (OR 1.40) and parent's education (OR 1.12) were significantly associated with ADHD. It has been highlighted the significance of deprivation of both family and financial comfort as primary indicators for ADHD in children. Moreover, children with ADHD were more likely to be males in the age group of 12 to 17.
