    Get PDF
    Objectives: This study aimed to examine the relationship between body mass index (BMI) z-scores and lifestyle-related factors including nutrition, physical activity, screen time and time spent sleeping in 6–10-year-old Omani children. Methods: This cross-sectional study included mother-child dyads that were recruited from five provinces in Oman. Children’s BMI measurements and questionnaires on nutrition intake, physical activity, screen time and time spent sleeping and a single-day dietary recall were collected. Results: A total of 197 dyads were included in this study. The children's mean age was 7.7 ± 1.6 years and 53% were female. In this study, 17.4% of the children were classified as overweight or obese. No significant relationship was found between the children's BMI z-scores and nutrition intake, moderate-to-vigorous physical activity time or screen time (P ≥0.05). Increased time spent sleeping at night was positively associated with childhood obesity (P <0.05). Conclusion: The relationship between obesity and caloric intake, physical activity and screen time among children younger than 10 years seems to be moderated by certain factors that need to be investigated. Qualitative studies and questionnaires that are culturally sensitive are therefore needed.Keywords: Children; Pediatric Obesity; Diet, Food, and Nutrition; Physical Activity; Screen Time; Sleep; Oman

    © 2016, Springer-Verlag Berlin Heidelberg. The Copper Age Coţofeni culture occupied a large territory which covers present day W Romania, NE Serbia, and NW Bulgaria. The Coțofeni people lived in settlements located on hill slopes and river terraces, as well as in caves. Their hand-modeled ceramic pottery is richly ornamented by incisions, incrustations, and “lentil bean” appliqués. Potsherds found in the “Peştera Mare de la Cerişor” (i.e., the “Great Cave of Cerişor”) located in Paleozoic crystalline limestones and dolomites (Southern Carpathians, Romania) were studied in terms of mineralogy and petrography by OM, XRD, and EMPA. The sherds consist of an Fe-rich illitic matrix embedding quartz, K-feldspar, muscovite, plagioclase, biotite, chlorite, various heavy minerals, metamorphic, magmatic and sedimentary lithoclasts, as well as soil concretions and chamotte. Within a temperature interval, spanning between ∼800 and ∼900 °C, three firing groups were roughly separated, based on the optical characteristics of the matrix and the intensity of the illite/muscovite diffraction peaks. Quaternary and Miocene rocks from the area were analyzed by XRD in order to determine the provenance of the raw materials

    In this longitudinal study we explored the relationships between plasma n-3 and n-6 polyunsaturated fatty acids (PUFAs) and Δ5 and Δ6 desaturase activities (D5D and D6D, respectively) and fasting lipids in youth with type 1 diabetes (T1D)

    “There are more important things to worry about”: attitudes and behaviours towards leisure noise and use of hearing protection in young adults

    Objective: Noise-induced hearing problems among young adults are increasing due to participation in activities where music is played at a loud volume. This study explored attitudes towards leisure noise, hearing protection, and perceived susceptibility to noise damage in young adults with no hearing problems. Understanding attitudes and behaviours will assist with the future development of strategies to improve awareness and use of hearing protection. Design: A qualitative study. Study Sample: Four focus groups, with 28 adults aged between 18 and 35 years (6 male; 22 female; mean age 23 years). Results: Using Framework Analysis, five themes emerged. Earplug use occurred when participants had experienced previous hearing damage. Others chose not to use earplugs because music venues are expected to be loud. Peer behaviours and opinions also had a strong influence over earplug use. A lack of knowledge of hearing related damage resulted in a lack of concern for hearing health and other health conditions taking priority. Conclusions: The challenge is to present hearing health messages that are relevant and accessible to young adults. Music and entertainment venues must also take greater responsibility to protect the hearing of its customers by at least informing visitors of the dangers of loud music

    The impact of COVID-19 on young people’s mental health, wellbeing and routine from a European perspective: A co-produced qualitative systematic review

    Get PDF
    Background The impact of the Covid-19 pandemic on young people’s (YP) mental health has been mixed. Systematic reviews to date have focused predominantly on quantitative studies and lacked involvement from YP with lived experience of mental health difficulties. Therefore, our primary aim was to conduct a qualitative systematic review to examine the perceived impact of the Covid-19 pandemic on YP’s (aged 10–24) mental health and wellbeing across Europe. Methods and findings We searched MEDLINE, PsycINFO, Embase, Web of Science, MEDRXIV, OSF preprints, Google, and voluntary sector websites for studies published from 1st January 2020 to 15th November 2022. European studies were included if they reported qualitative data that could be extracted on YP’s (aged 10–24) own perspectives of their experiences of Covid-19 and related disruptions to their mental health and wellbeing. Screening, data extraction and appraisal was conducted independently in duplicate by researchers and YP with lived experience of mental health difficulties (co-researchers). Confidence was assessed using the Confidence in the Evidence from Reviews of Qualitative Research (CERQual) approach. We co-produced an adapted narrative thematic synthesis with co-researchers. This study is registered with PROSPERO, CRD42021251578. We found 82 publications and included 77 unique studies in our narrative synthesis. Most studies were from the UK (n = 50; 65%); and generated data during the first Covid-19 wave (March-May 2020; n = 33; 43%). Across the 79,491 participants, views, and experiences of YP minoritised by ethnicity and sexual orientation, and from marginalised or vulnerable YP were limited. Five synthesised themes were identified: negative impact of pandemic information and restrictions on wellbeing; education and learning on wellbeing; social connection to prevent loneliness and disconnection; emotional, lifestyle and behavioural changes; and mental health support. YP’s mental health and wellbeing across Europe were reported to have fluctuated during the pandemic. Challenges were similar but coping strategies to manage the impact of these challenges on mental health varied across person, study, and country. Short-term impacts were related to the consequences of changing restrictions on social connection, day-to-day lifestyle, and education set-up. However, YP identified potential issues in these areas going forward, and therefore stressed the importance of ongoing long-term support in education, learning and mental health post-Covid-19. Conclusions Our findings map onto the complex picture seen from quantitative systematic reviews regarding the impact of Covid-19 on YP’s mental health. The comparatively little qualitative data found in our review means there is an urgent need for more high-quality qualitative research outside of the UK and/or about the experiences of minoritised groups to ensure all voices are heard and everyone is getting the support they need following the pandemic. YP’s voices need to be prioritised in decision-making processes on education, self-care strategies, and mental health and wellbeing, to drive impactful, meaningful policy changes in anticipation of a future systemic crisis

    Longitudinal associations of nutritional factors with glycated hemoglobin in youth with type 1 diabetes: the SEARCH Nutrition Ancillary Study

    Background: Hispanic women and children who become overweight or obese are at risk for developing prediabetes, type 2 diabetes, and cardiovascular disease later in life. Interdisciplinary interventions which target Hispanic women and their 3-5-year old children to improve nutrition and physical activity behaviors, manage adiposity and weight in mothers, and prevent excessive adiposity and weight gain trajectory in their children offer promise to break the intergenerational cycle. Methods: Using a randomized two-group, repeated measures experimental design, the goal of the proposed study is to investigate the efficacy of a 12-week nutrition and physical activity program including education, coping skills training, and home-based intervention in Hispanic women and their 3-5-year old children. The program includes 6 months of continued monthly contact to help overweight and obese Hispanic mothers and their children improve adiposity, weight (trajectory for children), health behaviors (nutrition and physical activity), and self-efficacy We will partner with two federally qualified health departments in Durham and Chatham counties, North Carolina to enroll participants. We will partner with community centers to deliver the intervention. A total of 294 Hispanic women with a BMI ≥ 25 kg/m2 and 294 Hispanic 3-5-year old children with a ≥ 25th BMI percentile will be enrolled over 4 years and randomized to the experimental or equal attention control group. Data will be collected at Time 1 (0 months [baseline]) to Time 2 (9 months [completion of the intervention]) and Time 1 to Time 3 (15 months [after 6 months with no contact from the study staff]). Data collected will include adiposity and weight in mothers and children (primary outcomes). Secondary outcomes will include health behaviors and self-efficacy in the mothers and in the children. We will also evaluate the cost of delivering the program for public health departments. We will use general linear mixed models to test the hypotheses. Discussion: Decreasing overweight and obesity in Hispanic women and slowing adiposity and weight gain trajectory in young Hispanic children is urgently needed to decrease morbidity, mortality, and future health care costs.
