The purpose of this study was to assess the relationship between physical self-concept and actual indicators of physical fitness in early and mid-adolescence. Physical self-concept plays a significant role in adolescence, as this phase of life is characterised by many physical, mental, and emotional changes. A total of 427 Slovenian boys and girls from two age groups (early and middle adolescence) were studied. Physical self-concept was assessed with the Slovenian version of Physical Self-Description Questionnaire, while the Sports-educational Chart was used to measure physical fitness. The results showed that the older group scored better on all measures of physical fitness, except for general endurance. In terms of age-related differences in physical self-concept, older adolescents showed poorer physical perceptions of their strength and flexibility and higher global self-esteem compared to their younger peers. Correlation analysis showed that physical self-concept and actual indicators of physical fitness were related, despite incomplete overlap between psychological dimensions and objective measures. The obtained results can be transferred to physical education, as the development of a positive physical self-concept is one of the most important educational goals.

The Relationship

The aim of this study was to validate the French version of the Career Decision-Making Difficulties Questionnaire (CDDQ) and to assess its measurement invariance across gender, age groups, countries, and student versus career counseling samples. We also examined the sensitivity of this instrument to discriminate a career counseling population from a general student sample. Third, we studied the relationship between career decision-making difficulties, career decision-making self-efficacy, and self-esteem in a sample of 1,748 French and French-speaking Swiss participants. A confirmatory factor analysis confirmed the overall hierarchical structure of the CDDQ. Multigroup analysis indicated that the level of invariance across groups almost always reached configural, metric, and scalar invariance. Differences between countries were very small, whereas differences between the general population and career counseling subsamples were much larger. Both self-esteem and self-efficacy significantly predicted career decision-making difficulties. Moreover, as expected, self-efficacy partially mediated the relationship between self-esteem and career decision-making difficulties.

The Relationship

Previous researchers have described the relation between physical self-concept and body mass in adolescents, but those relationships have not been clearly specified by gender. The purpose of this study is to explore physical self-concepts of normal-weight and over-weight Serbian adolescents with respect to gender. The sample consisted of 417 primary school students (229 boys and 188 girls) with the average age 13.6 (SD=0.73) years who were divided into normal-weight and overweight groups according to body mass index. To assess the multidimensional physical self-concept, Physical Self-Description Questionnaire (PSDQ) was administered. Results showed that overweight adolescents had significantly lower scores than normal-weight on all PSDQ scales except Health and Strength. Differences were greater among girls than boys. Discriminant analysis showed that the scales Body Fat, Endurance and Sports Competence best differentiated normal-weight boys from other students. Also, discriminant analysis showed that, besides the scale Body Fat, scales Flexibility, Self-Esteem, and Coordination best differentiated normal-weight girls from other students. Results indicate that for better understanding of the relationship between adolescent?s physical self-concept and body mass one must take gender into account. Results are potentially valuable for preventing overweight through physical education.

Dengan demikian bahwa ada hubungan antara konsep diri dan ketidakberdayaan dengan risiko bunuh diri pada remaja yang mengalami bullying di SMA Negeri 7 Kota Bogor. Kata kunci: bullying, konsep diri, ketidakberdayaan, risisko bunuh diri SELF-CONCEPT AND INEQUALITY CONNECTED WITH RISK OF SELF-SUFFICIENT IN ADOLESCENTS WHO HAVE BULLYING ABSTRACTBullying is a negative behavior that is carried out repeatedly by a person or group of people who are attacking because of an imbalance of power between the parties involved. Bullying actions can have a negative impact on victims and perpetrators in the future. These impacts include loneliness, poor academic achievement, adaptation difficulties, increased risk of substance use, involvement in criminal acts and susceptibility to mental emotional disorders such as anxiety, insomnia, substance abuse, depression, low self-esteem, interpersonal difficulties, disturbances self concept, and depression (helplessness). The purpose of this study was to determine the relationship between self-concept and powerlessness with the risk of suicide in adolescents who experienced bullying in SMA Negeri 7 Kota Bogor. This research is a quantitative study using a cross-sectional study method with a correlation study design approach. The sample in this study amounted to 183 people obtained from random sampling techniques. The results showed that based on the results of the relationship test using Chi-Square between self-concept and powerlessness, the value of ρ (0,000) was smaller than the value of α (0.05), while the test of the relationship between self-concept and risk of suicide obtained a value of ρ (0.013 ) is smaller than the value of α (0.05). Thus that there is a relationship between self-concept and powerlessness with the risk of suicide in adolescents who experience bullying in SMA Negeri 7 Kota Bogor. Keywords: bullying, self-concept, helplessness, suicide risk

BACKGROUND An electronic personal health record (ePHR), also known as a personal health record (PHR), was broadly defined as an electronic application through which individuals can access, manage, and share their health information in a secure and confidential environment. Although ePHRs can benefit individuals as well as caregivers and healthcare providers, the use of ePHRs among individuals continues to remain low. The relationship between age and ePHRs use has been documented in previous studies, which indicated younger age was related to higher ePHRs use, and patients who are younger were more likely to use ePHRs. OBJECTIVE The current study aims to examine the relationship between human-technology interaction factors and ePHRs use among adults, and then compare the different effects of human-technology interaction factors on ePHRs use between younger adults (18-54 years old) and older adults (55 years of age and over). METHODS We analyzed the from the Health Information National Trends Survey (HINTS5, Cycle 3) collected from U.S. adults aged 18 years old and over in 2019. Descriptive analysis was conducted for all variables and each item of ePHRs use. Bivariate tests (Pearson test for categorical variable and F-test for continuous variables) were conducted over four age groups. Lastly, adjusting for socio-demographics and healthcare resources, a weighted multiple linear regression was conducted to examine the relationship between human-technology interaction factors and ePHRs use. RESULTS The final sample size was 1,363 and divided into two age groups: 18-54 years old and 55 years of age and older. The average level of ePHRs use was low (Mean=2.76, range=0-8). There is no significant difference on average ePHRs use between two age groups. Including clinical notes was positively related to ePHRs use in both groups: 18-54 years old (beta=0.28, P<0.01), 55 years old and above (beta=0.15, P<0.01). While accessing ePHRs using a smartphone app was only associated with ePHRs use among younger adults (beta=0.29, P<0.001), ease to understand health information in ePHRs was positively linked to ePHRs use only among older adults (beta=0.13, P<0.01). CONCLUSIONS This study found that including clinical notes was positively related to ePHRs use in both age groups, which suggested that including clinical notes as a part of ePHRs might improve the effective use of ePHRs among patients. Moreover, accessing ePHRs using a smartphone app was associated with higher ePHRs use among younger adults while ease of understanding health information in ePHRs was linked to higher ePHRs use among older adults. The design of ePHRs should provide the option of being accessible through mobile devices to promote greater ePHRs use among young people. For older adults, providers could add additional notes to explain health information recorded in the ePHRs.

The present studies examine the hypothesis that multiple adrenergic neuroeffector mechanisms are not fully developed in fetal, compared with adult, ovine middle cerebral arteries. In arteries denuded of endothelium and pretreated with 1 μM atropine to block involvement of muscarinic receptors, 10 μM capsaicin to deplete sensory peptidergic neurons, and 10 μM nitro-l-arginine methyl ester (l-NAME) to block possible influences from nitric oxidergic innervation, transmural stimulation at 16 Hz increased contractile tensions to 9.5 ± 3.7% ( n = 6) of the potassium maximum in adult arteries. Corresponding values in fetal arteries, however, were significantly less and averaged only 1.1 ± 0.6% ( n =10). However, postsynaptic sensitivity to norepinephrine (NE) was similar in the two age groups; NE pD2 values (−log EC50) averaged 6.11 ± 0.12 ( n = 6) and 6.33 ± 0.09 M ( n = 9) in fetal and adult arteries, respectively. Similarly, NE content measured via HPLC was also similar in the two age groups and averaged 32.4 ± 5.0 ( n = 17) and 32.5 ± 3.9 ng/ng wet wt ( n = 13) in fetal and adult middle cerebral arteries, respectively. In contrast, stimulation-induced NE release was greater in fetal than in adult arteries, whether calculated as total mass released [883 ± 184 ( n = 17) vs. 416 ± 106 pg NE/mg wet wt ( n = 13)] or as fractional release [51.1 ± 5.3 ( n = 17) vs. 22.8 ± 3.8 pg/pg NE content per pulse × 10−6]. Measured as an index of synaptic density, neuronal cocaine-sensitive NE uptake was similar in fetal and adult arteries [1.55 ± 0.40 ( n = 10) and 1.84 ± 0.51 pmol/mg wet wt ( n = 7), respectively]. Overall, age-related differences in postsynaptic sensitivity to NE, NE release, and NE uptake capacity cannot explain the corresponding age-related differences in response to stimulation. The data thus suggest that total synaptic volume and cleft width, in particular, are probably greater and/or that adrenergic corelease of vasoactive substances other than NE is altered in fetal compared with adult middle cerebral arteries.

Abstract Serum levels of insulin-like growth factor 1 (IGF-1) and measures of adiposity, such as body mass index (BMI), are associated with susceptibility to age-related diseases. Previous reports of the relationship between IGF-1 and BMI ranged from positive to negative to no relationship, perhaps because previous reports studied different age cohorts. Using data on 4270 participants (aged 24-110 years) from the Long Life Family Study, we investigated the relationship between IGF-1 and BMI overall and by age groups. IGF-1 and BMI were positively correlated in the total sample (β=0.161, r2= 0.0038, p=1.8-05). However, further analyses revealed that the relationship between IGF-1 and BMI varied by age quartile: in the 1st quartile (24-58yo) the relationship was negative (β=−0.204, r2= 0.011, p=0.0008); in the 2nd quartile (59-66yo) the relationship was negative but non-significant (β=−0.069, r2= 0.0012, p=0.28); in the 3rd quartile (67-86yo) the relationship was positive but non-significant (β=0.106, r2= 0.002, p=0.13); and in the 4th quartile (87-110yo) the relationship was positive (β=0.388, r2= 0.019, p=1.2−05). This pattern did not differ by sex. We also detected a similar age-related pattern between IGF-1 and BMI using an independent dataset (NHANES III), comprising 2550 men and women aged 20-90 years. Our results may clarify some of the inconsistency in previous literature about the relationship between IGF-1 and BMI. Additional studies of IGF-1 and adiposity measures are needed to better understand the underlying mechanisms involved.

Abstract Background Serum levels of insulin-like growth factor 1 (IGF-1) and body mass index (BMI) are both associated with susceptibility to age-related diseases. Reports on the correlation between them have been conflicting, with both positive to negative correlations reported. However, the age ranges of the participants varied widely among these studies. Methods Using data on 4241 participants (aged 24–110) from the Long Life Family Study, we investigated the relationship between IGF-1 and BMI by age groups using regression analysis. Results When stratified by age quartile, the relationship between IGF-1 and BMI varied: in the first quartile (Q1, 20–58 years) the relationship was negative (β = −0.2, p = .002); in Q2 (58–66 years) and Q3 (67–86 years) the relationship was negative (β = −0.07, β = −0.01, respectively) but nonsignificant; and in Q4 (87–110 years) the relationship was positive (β = 0.31, p = .0002). This pattern did not differ by sex. We observed a similar age-related pattern between IGF-1 and BMI among participants in the third National Health and Nutritional Examination Survey. Conclusions Our results that the relationship between IGF-1 and BMI differs by age may explain some of the inconsistency in reports about their relationship and encourage additional studies to understand the mechanisms underlying it.

The Relationship

Vitamin D requirements are thought to vary with age, but there is little comparative evidence for this. One goal in establishing a vitamin D requirement is to avoid secondary hyperparathyroidism. We studied 1741 euthyroid, thyroid clinic outpatients without evidence of calcium abnormalities, ranging in age from 19 to 97 yr, whose serum and urine had been analyzed for calcium, vitamin D, and parathyroid status. We found no effect of age on the 25-hydroxyvitamin D [25(OH)D] concentration associated with specific vitamin D intakes, and there was no relationship between 25(OH)D and 1,25hydroxyvitamin D [1,25(OH)2D]. In every age group, serum 1,25(OH)2D declined with increasing creatinine (P &lt; 0.001). What changed with age included creatinine, which correlated with 25(OH)D (r = 0.146, P &lt; 0.001) only in the youngest age group (19–50 yr) but not in the older age groups (P &gt; 0.1). Creatinine did not correlate with PTH in the youngest age group, but the relationship became significant as age increased (e.g. for the elderly, r = 0.365, P &lt; 0.001). Linear regression of log PTH vs. log 25(OH)D agreed with the natural shape of the relationship observed with scatterplot smoothing, and this showed no plateau in PTH as 25(OH)D increased. We compared PTH concentrations among age groups, based on 20 nmol/liter increments in 25(OH)D. Mean PTH in adults older than 70 yr was consistently higher than in adults younger than 50 yr (P &lt; 0.05 by ANOVA and Dunnett’s t test). PTH levels of the elderly who had 25(OH)D concentrations greater than 100 nmol/liter matched PTH of younger adults having 25(OH)D concentrations near 70 nmol/liter. This study shows that all age groups exhibit a high prevalence of 25(OH)D insufficiency and secondary hyperparathyroidism. Older adults are just as efficient in maintaining 25(OH)D, but they need more vitamin D to produce the higher 25(OH)D concentrations required to overcome the hyperparathyroidism associated with their diminishing renal function.
