The influence of parenting style on health related behavior of children : findings from the ChiBS study

Objective: Exploring associations between parenting behavior and children's health related behavior including physical activity, sedentary behavior, diet and sleep. Methods: We recruited 288 parents and their children (6-12y old). Children's weight and height were measured. Fat percentage was determined by air displacement plethysmography. Parents reported socio-demographic data, sleep information, physical activity and sedentary behavior of their child and completed the Comprehensive General Parenting Questionnaire (CGPQ) and a Food Frequency Questionnaire. Children completed the Dutch Eating Behavior Questionnaire. Associations between parenting behavior (CGPQ) and children's health related behavior were assessed with univariate and multiple regression analyses. Results: A small positive correlation was found between sweet food consumption frequency and "coercive control" (r = 0.139) and a small negative correlation between fruit and vegetables consumption frequency and "overprotection" (r = -0.151). Children consumed more frequently soft drinks when their parents scored lower on "structure" (r = -0.124) and higher on "overprotection" (r = 0.123); for the light soft drinks separately, a small positive correlation with "behavioral control" was found (r = 0.172). A small negative correlation was found between "emotional eating" and "structure" (r = -0.172) as well as "behavioral control" (r = -0.166). "Coercive control" was negatively correlated with the child's sleep duration (r = -0.171). After correction for confounding factors, the following significant associations were found: (1) a small negative association between "structure" and soft drinks consumption (beta = -0.17 for all soft drinks and -0.22 for light soft drinks), (2) a small positive association between "behavioral control" and light soft drinks (beta = 0.34), (3) a small positive association of "nurturance" and "coercive control" with sedentary behavior (beta = 0.16 for both parent constructs) and (4) a small negative association between the parenting construct "coercive control" and sleep duration (beta = -0.23). Conclusion: The significant but small associations between parenting constructs and the investigated variables suggest that different aspects of parenting style play an important role in the genesis of the health related behavior of children. Overall, our findings suggest that health professionals should encourage parents to apply the more positive parenting constructs i.e., more "structure" and "behavioral control", and less "coercive control". They could, for instance, supervise and manage their child's activities and help their child to achieve certain goals

Evidence that the TRH-like peptide pyroglutamyl-glutamyl-prolineamide in human serum may not be secreted by the pituitary gland

Recent studies have revealed that TRH-like immunoreactivity (TRH-LI) in human serum is predominantly pGlu-Glu-ProNH2 (< EEP-NH2), a peptide previously found in, among others tissues, the pituitary gland of various mammalian species. In the rat pituitary, < EEP-NH2 is present in gonadotrophs and its pituitary content is regulated by gonadal steroids and gonadotrophin-releasing hormone (GnRH). Hence, we reasoned that < EEP-NH2 in human serum may also arise, at least in part, from the pituitary, and that its secretion may correlate with that of gonadotrophins. Therefore, blood was simultaneously sampled from both inferior petrosal sinuses, which are major sites of the venous drainage of the pituitary gland, and a peripheral vein from seven patients with suspected adrenocorticotrophin-secreting pituitary tumours. In addition, in six postmenopausal and six cyclic women, peripheral vein blood was collected at 10-min intervals for 6 h, then a standard 100 micrograms GnRH test was performed. In the sera, TRH-LI was estimated by RIA with antiserum 4319, which binds most tripeptides that share the N- and C-terminal amino acids with TRH (pGlu-His-ProNH2). In addition, LH and FSH were measured in these sera b

Aerobic and strength exercises for youngsters aged 12 to 15: what do parents think?

BACKGROUND: Although strength exercises evidently have both physiological and psychological health benefits across all ages, they are erroneously considered to adversely affect health status in youngsters. The aim of this study was to examine parental attitudes towards their child's physical activity in general, as well as aerobic and strength exercises in particular. METHODS: In total, 314 parents from an online panel representative of the Dutch population completed an online survey about their own physical activity and that of their child (12-15 years old). The study also explored reasons for non-participation, and attitudes about the parents' own and their child's physical activity level. RESULTS: Parents consistently reported a positive attitude towards aerobic exercises, but a less positive attitude regarding strength exercises. Parents were more likely to indicate that their child was not allowed to participate in strength exercises (29.6 %) than aerobic exercises (4.0 %). They thought that strength exercises could interfere with optimal physical development. CONCLUSIONS: This study consistently shows that parents have a positive attitude towards aerobic exercises, but a less positive attitude regarding strength exercises. We suggest testing interventions to increase parental understanding of the advantages of and possibilities for (e.g., facilities) strength training on their child's health

The effect of time delay in plant-pathogen interactions with host demography

Background: There is a need for valid and comprehensive measures of parental influence on children's energy balance-related behaviours (EBRB). Such measures should be based on a theoretical framework, acknowledging the dynamic and complex nature of interactions occurring within a family. The aim of the Family & Dietary habits (F&D) project was to develop a conceptual framework identifying important and changeable family processes influencing dietary behaviours of 13-15 year olds. A second aim was to develop valid and reliable questionnaires for adolescents and their parents (both mothers and fathers) measuring these processes. Methods: A stepwise approach was used; (1) preparation of scope and structure, (2) development of the F&D questionnaires, (3) the conducting of pilot studies and (4) the conducting of validation studies (assessing internal reliability, test-retest reliability and confirmatory factor analysis) using data from a cross-sectional study. Results: The conceptual framework includes psychosocial concepts such as family functioning, cohesion, conflicts, communication, work-family stress, parental practices and parental style. The physical characteristics of the home environment include accessibility and availability of different food items, while family meals are the sociocultural setting included. Individual characteristics measured are dietary intake (vegetables and sugar-sweetened beverages) and adolescents' impulsivity. The F&D questionnaires developed were tested in a test-retest (54 adolescents and 44 of their parents) and in a cross-sectional survey including 440 adolescents (13-15 year olds), 242 mothers and 155 fathers. The samples appear to be relatively representative for Norwegian adolescents and parents. For adolescents, mothers and fathers, the test-retest reliability of the dietary intake, frequencies of (family) meals, work-family stress and communication variables was satisfactory (ICC: 0.53-0.99). Barratt Impulsiveness Scale-Brief (BIS-Brief) was included, assessing adolescent's impulsivity. The internal reliability (Cronbach's alphas: 0.77/0.82) and test-retest reliability values (ICC: 0.74/0.77) of BIS-Brief were good. Conclusions: The conceptual framework developed may be a useful tool in guiding measurement and assessment of the home food environment and family processes related to adolescents' dietary habits, in particular and for EBRBs more generally. The results support the use of the F&D questionnaires as psychometrically sound tools to assess family characteristics and adolescent's impulsivity

Silencing markers are retained on pericentric heterochromatin during murine primordial germ cell development

Background: In the nuclei of most mammalian cells, pericentric heterochromatin is characterized by DNA methylation, histone modifications such as H3K9me3 and H4K20me3, and specific binding proteins l

Repair of exogenous DNA double-strand breaks promotes chromosome synapsis in SPO11-mutant mouse meiocytes, and is altered in the absence of HORMAD1

Repair of SPO11-dependent DNA double-strand breaks (DSBs) via homologous recombination (HR) is essential for stable homologous chromosome pairing and synapsis during meiotic prophase. Here, we induced radiation-induced DSBs to study meiotic recombination and homologous chromosome pairing in mouse meiocytes in the absence of SPO11 activity (Spo11YF/YF model), and in the absence of both SPO11 and HORMAD1 (Spo11/Hormad1 dko). Within 30 min after 5 Gy irradiation of Spo11YF/YF mice, 140–160 DSB repair foci were detected, which specifically localized to the synaptonemal complex axes. Repair of radiation-induced DSBs was incomplete in Spo11YF/YF compared to Spo11+/YF meiocytes. Still, repair of exogenous DSBs promoted partial recovery of chromosome pairing and synapsis in Spo11YF/YF meiocytes. This indicates that at least part of the exogenous DSBs can be processed in an interhomolog recombination repair pathway. Interestingly, in a seperate experiment, using 3 Gy of irradiation, we observed that Spo11/Hormad1 dko spermatocytes contained fewer remaining DSB repair foci at 48 h after irradiation compared to irradiated Spo11 knockout spermatocytes. Together, these results show that recruitment of exogenous DSBs to the synaptonemal complex, in conjunction with repair of exogenous DSBs via the homologous chromosome, contributes to homology recognition. In addition, the data suggest a role for HORMAD1 in DNA repair pathway choice in mouse meiocytes

Emotional Exhaustion, Depersonalization, and Feelings of Decreased Personal Accomplishment Oh My: What Message Are We Sending To Our Students?

PURPOSE: The purpose of this presentation is to address the issue of burnout amongst PTs through the lens that addressing this issue in our profession may very well be the first step in building resilience in the academic and clinical environments. METHODS AND/OR DESCRIPTION: Physical therapy student well-being is a priority for academic institutions. Yet, are we, as academic and clinical faculty, who are responsible for promoting student well-being, “well” ourselves? Could burnout of our academic and clinical faculty impact our student’s wellness? Burnout is a syndrome described as emotional exhaustion, depersonalization, and feelings of decreased personal accomplishment. All effects that can influence our own health, work environment, and relationship with others. During this session, we will review the literature regarding the prevalence of burnout amongst PTs and cite factors that may contribute to burnout. We will describe its effects on the health of the provider, atmosphere of the work environment, student instruction and well-being, and ultimately the quality of care received by our patients. Finally, drawing from current research, we will investigate solutions to mitigate burnout in academic and clinical faculty to promote wellness and resilience. RESULTS/OUTCOMES: There is evidence PTs are experiencing a moderate level of burnout at an incidence that, in some cases, is higher than other healthcare professionals. Both job related stresses as well as intrinsic individual factors have been cited as contributing to burnout. This includes factors such as lack of communication and connectedness, diminished personal achievement, time constraints, lack of support from supervisors and colleagues, role conflict and ambiguity, and failure to utilize a task-related coping style. Results show that the effects of burnout can include decreased psychological, physical, and cognitive function, somatic and physical arousal, decreased immunity, morale, and productivity, absenteeism, job turnover, and alcohol and drug abuse. Further, those experiencing burnout develop a negative self-concept, have a poor attitude towards their job including a loss of concern for their patients, co-workers, and themselves. Solutions to alleviate burnout and promote well-being in physical therapists include the use of social network analysis, teamwork, communication, leadership, professional identity programs, targeted work unit interventions, use of rewards and incentives, flexibility and work life integration, and self-care. CONCLUSIONS/RELEVANCE TO CONFERENCE THEME: As academic and clinical faculty, we are in a position to have a major impact on our students. If we want to promote resilience and well-being in our students, it is important that we ourselves are not experiencing burnout and are role-modeling strategies that promote resilience. The effects of burnout are significant and will not only take their toll on our own health but also can influence our relationships with our students. It is important that when building resilience in the academic and clinical environments, we address the needs of both the faculty and the students

Adaptable lightweight structures to minimise material use

The optimal use of materials is highly necessary and a key issue for the near future. World’s current demand on resources and waste production has an enormous impact on the environment, which will even dramatically increase when future’s explosion on population takes place. The high contribution to this by the building industry gives it a big responsibility to reduce the concerning figures of material use. This paper describes an approach in which structures are optimised with the use of adaptability. Structural optimisation is normally only done for static structures, while they are loaded in a dynamic way, meaning loadings which are changing in time, level and location. When structures are made adaptable to these dynamic environmental conditions the adaptability can significantly decrease the structural materials needed by increase of its efficiency. Within this paper the structural adaptability is categorized in passive and active adaptability; passive adaptability using a higher deformation acceptance (flexibility) and active adaptability actively controlling the structure with actuators under different circumstances in a static or dynamic adaptive way. The required higher deformation acceptance for passive adaptable optimisation, and the non-efficient influences of actuators for permanent loadings, like self-weight, does focus the research within the field of lightweight structures. Within the chair ISD of the Eindhoven Technical University ‘adaptable lightweight structures’ is one of the key research topics
