Relationship between the body mass index and the ponderal index with physical fitness in adolescent students.

Background: The relationship between the Body Mass Index (BMI) with physical fitness in children and adolescent populations from diverse regions are consistent. However, the relationship between the Ponderal Index (PI) with physical fitness, based on what is known to date, has not been examined in depth.

Validity and reliability of a social skills scale among Chilean health sciences students: A cross-sectional study.

Currently, there is a growing need to assess social skills in young university students since the use and application of these scales can provide benefits in different situations, such as work, education, clinical and psychological. The objective of the study was to verify the validity and reliability of a social skills scale (SS) for students from three professional health sciences programs in Chile. This information will provide understanding and development of SS among health care team members and between them and patients.

Comparison of Anthropometric Indicators That Assess Nutritional Status From Infancy to Old Age and Proposal of Percentiles for a Regional Sample of Chile.

Anthropometric variables are used to evaluate health, dietary status, disease risks, and changes in body composition. The purpose of this study was to compare weight, height, and Body Mass Index (BMI) with American references from the National Center for Health Statistics (NCHS-2012), using BMI and Tri-Ponderal Mass Index (TMI) to propose percentiles for evaluating nutritional status of children, adolescents, and adults, ages 5-80 years old. A descriptive cross-sectional study was conducted in 15,436 (8,070 males and 7,366 females) children, youths and adults in the Maule region (Chile).

Methods: A cross-sectional study was carried out with 3,013 students.

Family care across diverse cultures: Re-envisioning using a transnational lens.

In an increasingly globalized world, the importance of developing a more culturally complex understanding of family care has been clearly identified. This study explored family care across three different cultural groups - Chinese, South Asian, and Latin American - living in a metropolitan, Pacific-West, Canadian city. In-depth qualitative interviews were conducted with 29 family members from one of the three family groups exploring how they practiced 'care' for their aging, often frail, relatives.

Ultrasound reference values for the calcaneus of children and adolescents at moderate altitudes in Peru.

Objective: a) Establish reference values for bone parameters by using the speed of sound (SOS, m/s) of broadband ultrasound attenuation (BUA, dB/MHz) and establish a bone quality index (BQI=αSOS+βBUA) for children and adolescents living in a region of moderate altitude, b) compare bone parameters with an international standard (with different ethnic, socio-economic, and lifestyle backgrounds) by using ultrasound of the calcaneus (heel bone) (QUS).

Methods: A descriptive cross-sectional study was carried out with children and adolescents between the ages of 6.0 and 16.

Physical Growth and Body Adiposity Curves in Students of the Maule Region (Chile).

Physical growth and body adiposity patterns provide relevant information to infer the nutritional and health status of students. Our objectives were (a) to compare the variables of body adiposity and physical growth of Chilean children and adolescents with data from the CDC-2012 and international studies, and (b) to develop regional reference curves to evaluate growth and body adiposity. 8,261 children and adolescents were studied.

Normative data for handgrip strength in children and adolescents in the Maule Region, Chile: Evaluation based on chronological and biological age.

Background: Hand grip strength (HGS) is associated with a number of causes resulting in cardiovascular death, in addition to bone fragility, and the presence of sarcopenia. The goal of our study was to analyze HGS of students based on chronological and biological age and propose normative standards for children and adolescents from Chile.

Methods: We studied 4604 school children of both sexes between the ages of 6.

Reference norms for evaluating maximum expiratory flow of children and adolescents of the Maule Region in Chile.

Background: The norms for evaluating the maximum expiratory flow (MEF) usually are developed according to chronological age and height. However, to date, little research has been conducted using reference values that take into account the temporal changes of biological maturation. The objectives of this study were to (a) compare the MEF with those of other international studies, (b) align the MEF values with chronological and biological age, and (c) propose reference standards for children and adolescents.
