An observational study of adolescent health outcomes associated with school-based health service utilization: A causal analysis.

Objective: Our aim is to examine the unbiased association between use of school-based health services (SBHS) and student health outcomes.

Data Sources: Data are from a nationally representative health and well-being survey of 8500 New Zealand high school students from 91 high schools.

Study Design: Student data were linked to the level of SBHS available to them: no SBHS, regular clinics from visiting health professionals, a health professional onsite, or a health team onsite.

Characteristics of school-based health services associated with students' mental health.

Objective School-based health services (SBHS) have been shown to improve access to mental health services but the evidence of their effectiveness on students' mental health is lacking. Our objective was to examine associations between variation in the provision of SBHS and students' mental health. Methods A cross-sectional analysis of a nationally representative health and well-being survey of 8500 New Zealand high school students conducted in March-November 2012.

Quantification and clinical application of carboplatin in plasma ultrafiltrate.

Carboplatin is a chemotherapy drug used in a variety of cancers with the primary toxicity being exposure-dependant myelosuppression. We present the development and validation of a simple, robust inductively coupled plasma mass spectrometry (ICP-MS) method to measure carboplatin in plasma ultrafiltrate. Plasma ultrafiltrates samples were prepared using Amicon Ultra 30,000da cut-off filters and then diluted with ammonia EDTA before ICP-MS analysis.

Equation-free mechanistic ecosystem forecasting using empirical dynamic modeling.

It is well known that current equilibrium-based models fall short as predictive descriptions of natural ecosystems, and particularly of fisheries systems that exhibit nonlinear dynamics. For example, model parameters assumed to be fixed constants may actually vary in time, models may fit well to existing data but lack out-of-sample predictive skill, and key driving variables may be misidentified due to transient (mirage) correlations that are common in nonlinear systems. With these frailties, it is somewhat surprising that static equilibrium models continue to be widely used.

Family meals and the well-being of adolescents.

Aim: The current study describes the relationships between family meals and family connectedness, parental monitoring and parent-child communication and determines if frequent family meals are associated with better mental well-being and fewer risk-taking behaviours among adolescents.

Methods: Data were collected as part of Youth'07, a nationally representative survey of the health and well-being of secondary school students in New Zealand (n = 9107).

Results: Frequent family meals were positively associated with better indicators of family relationships (P < 0.

Family meals among New Zealand young people: relationships with eating behaviors and body mass index.

Objective: To examine the relationship between family meals and nutrition behaviors of adolescents.

Design: Secondary analysis of Youth'07, a nationally representative survey.

Setting: Secondary schools in New Zealand.

Do schools influence student risk-taking behaviors and emotional health symptoms?

Purpose: Many schools engage in health promotion, health interventions, and services aimed at improving the health and well-being outcomes for students. The purpose of this study was to examine the effects of schools on student health risk-taking behaviors and depressive symptoms.

Method: A nationally representative sample (n = 9,056) of students from 96 secondary schools completed a health and well-being survey using Internet Tablets that included questions on school climate, health risk-taking behaviors, and mental health.

Health and well-being of young people who attend secondary school in Aotearoa, New Zealand: what has changed from 2001 to 2007?

Aim: To describe the changes in the health and well-being of secondary school students from 2001 to 2007.

Methods: A total of 9107 secondary school students were randomly selected to participate in a comprehensive health and well-being survey using Internet tablets conducted in 2007. Comparisons are made with the first health and well-being survey conducted in 2001.
