Adequate adherence to benzathine penicillin secondary prophylaxis following the diagnosis of rheumatic heart disease by echocardiographic screening.

AIMS: The primary aim of this study was to determine adherence to benzathine penicillin (BPG) for individuals diagnosed with rheumatic heart disease (RHD) by echocardiographic screening between 2007-2012. METHODS: BPG records were obtained for 57 patients, median age 12 at time of diagnosis. A 'days at risk' analysis was undertaken. Annual adherence was calculated for each individual. A comparison with the Wellington region's Rheumatic Fever 2013 adherence data was undertaken. RESULTS: Adherence to BPG was good with a median follow-up time of 5.8 years. Days at risk analysis: median 0% at year one and 2.7% at year five. The median adherence for the entire cohort over the entire follow-up period was 92%, range 0-100%. There was no difference of proportions of late doses compared to the Wellington region. Median adherence was higher for register based (94%, n=48) compared to primary health care penicillin delivery (37%, n=7), p<0.005. During follow-up, 30% of the cohort moved between regions or overseas. CONCLUSIONS: Good adherence rates are achievable for secondary prophylaxis when RHD is diagnosed by echocardiographic screening. This likely reflects the benefit of rheumatic fever registers and community nursing services rather than the pathway of the diagnosis for RHD.

Family acceptability of school-based echocardiographic screening for rheumatic heart disease in a high-risk population in New Zealand.

AIM: Echocardiographic screening for rheumatic heart disease has been piloted in high-risk areas in New Zealand and internationally, and fulfils most of the criteria for a targeted screening programme. The question of acceptability of rheumatic heart disease screening has not been assessed, and the aim of our study was to assess parental acceptability of a school-based echocardiographic screening programme in a high-risk population in New Zealand. METHODS: A post-screening questionnaire was developed to survey parents of children who underwent echocardiographic screening. The families of 34 children with abnormal scan results and a sample of 80 children with normal scan results were surveyed by phone within 4 months of screening. RESULTS: Positive results were seen in all survey questions in both normal and abnormal scan groups. All families were supportive of an ongoing screening programme. Of children with abnormal results, 62% of their parents reported that they would treat their child differently; however, all responses were positive health-promoting outcomes. CONCLUSION: The study showed strong positive support for school-based echocardiographic screening by a community with high acute rheumatic fever incidence. The study did not detect any short-term negative effects in those with abnormal results. The survey result shows family and community support for the establishment of echocardiographic screening programmes in high acute rheumatic fever areas provided there is adequate infrastructural support.

Crohn disease: effect on children's lifestyles.

BACKGROUND AND AIM: Crohn disease (CD) presents a range of physical, social, and psychological challenges, and can adversely affect the quality of life of those affected by it. The present study aimed to investigate the health-related quality of life of paediatric patients with CD in the Wellington region. Measuring health-related quality of life assists with resource allocation decisions and assesses various forms of interventions. METHODS: Patients ages 9 to 18 years with CD in the Wellington region were assessed using the IMPACT-III inflammatory bowel disease-specific questionnaire (n = 16). Eight participants filled it out and returned it by post; the remaining 8 filled it out in a meeting with the researcher and then underwent cognitive debriefing as part of a cross-cultural adaptation of the questionnaire. RESULTS: Of a maximum possible value of 175, the total health-related quality of life score had a mean value of 119.2 (standard deviation 30.7). Using Spearman rank correlation analysis, significant findings included a positive correlation between disease duration and quality of life (ρ = 0.534, sig. <0.05) and a negative correlation between disease activity and quality of life (ρ = -0.596, sig. <0.05). Qualitative information included difficulties in coping with long-term and unpleasant treatments and feelings of isolation. CONCLUSIONS: Children with Crohn disease in the Wellington region may benefit from age-specific social and psychological support. Because there is limited information on quality of life in young patients with CD in New Zealand, the results of the present study may be used as baseline data for future studies.

Risk factors for obesity in 7-year-old European children: the Auckland Birthweight Collaborative Study.

OBJECTIVE: To identify risk factors associated with obesity in primary school children, with a particular focus on those which can be modified. To identify critical periods and growth patterns in the development of childhood obesity. METHODS: 871 New Zealand European children were enrolled in a longitudinal study at birth and data were collected at birth, 1, 3.5 and 7 years of age. Data collected at 7 years included weight, height, bioelectrical impedance analysis (BIA), television viewing time and a 24 h body movement record (actigraphy). The outcome measure was percentage body fat (PBF), which was calculated at 3.5 and 7 years using BIA. Univariate and multiple regression analyses were carried out using PBF as a continuous variable. RESULTS: Multivariable analysis found maternal overweight/obesity, maternal age, female gender, sedentary activity time and hours of television viewing to be independently associated with PBF at 7 years. Growth variables (birth weight, rapid weight gain in infancy, early (1-3.5 years) and middle childhood (3.5-7 years)) were also independently associated with adiposity at 7 years. There was a strong correlation between PBF at 3.5 years and PBF at 7 years. CONCLUSIONS: Many primary school aged children start on the trajectory of obesity in the preschool years, which suggests interventions need to start early. Maternal overweight/obesity, television watching, sedentary activity time and rapid weight gain in infancy, early and middle childhood are risk factors for childhood obesity, and are all potentially modifiable.
