Attendance for general practitioner (GP) care of childhood asthma varies widely in New Zealand (NZ). There is little current research to account for the variations, although groups such as Maori and Pacific peoples have traditionally faced barriers to accessing GP care. This paper aims to describe and account for attendance levels for GP asthma care among 6-9 year-olds with moderate to severe asthma in Auckland, NZ. During 2002, randomly selected schools identified all 6-9 year-olds with possible breathing problems. Completion of a questionnaire by each parent/guardian indicated which children had moderate to severe asthma, and what characteristics influenced their access to GP asthma care. A multilevel, negative binomial regression model (NBRM) was fitted to account for the number of reported GP visits for asthma, with adjustment for clustering within schools. Twenty-six schools (89.7 percent) identified 931 children with possible breathing problems. Useable questionnaires were returned to schools by 455 children (48.9 percent). Results indicated 209 children with moderate to severe asthma, almost one in every three reportedly making 5 or more GP visits for asthma in the previous year. Maori, Pacific and Asian children were disproportionately represented among these 'high attendees'. Low attendees (0-2 visits) were mainly NZ Europeans. The NBRM (n = 155) showed that expected visits were increased by perceived need, ill-health, asthma severity and, in particular, Maori and Pacific child ethnicity. It may be that Maori and Pacific children no longer face significant barriers to accessing GP asthma care. However, more likely is that barriers apply only to accessing routine, preventative care, leading to poor asthma control, exacerbations requiring acute care, and paradoxically an increase in GP visits. That barriers may increase total numbers of visits challenges the assumption, for all health systems, that access can be defined in terms of barriers that must be overcome to obtain health care.

Objectives. Although referrals for nonsynostotic plagiocephaly (NSP) have increased in recent years, the prevalence, natural history, and determinants of the condition have been unclear. The objective of this study was to assess the prevalence and natural history of NSP in normal infants in the first 2 years of life and to identify factors that may contribute to the development of NSP. Methods. Two hundred infants were recruited at birth. At 6 weeks, 4 months, 8 months, 12 months, and 2 years, the head circumference shape was digitally photographed, and head shape was quantified using custom-written software. At each age, infants were classified as cases when the cephalic index was [is greater than or equal to] 93% and/or the oblique cranial length ratio was [is greater than or equal to] 106%. Neck rotation and a range of infant, infant care, socioeconomic, and obstetric factors were assessed. Results. Ninety-six percent of infants were followed to 12 months, and 90.5% were followed to 2 years. Prevalence of plagiocephaly and/or brachycephaly at 6 weeks and 4, 8, 12, and 24 months was 16.0%, 19.7%, 9.2%, 6.8%, and 3.3% respectively. The mean cephalic index by 2 years was 81.6% (range: 72.0%-102.6%); the mean oblique cranial length ratio was 102.6% (range: 100.1%-109.4%). Significant univariate risk factors of NSP at 6 weeks include limited passive neck rotation at birth, preferential head orientation, supine sleep position, and head position not varied when put to sleep. At 4 months, risk factors were male gender, firstborn, limited passive neck rotation at birth, limited active head rotation at 4 months, supine sleeping at birth and 6 weeks, lower activity level, and trying unsuccessfully to vary the head position when putting the infant down to sleep. Conclusions. There is a wide range of head shapes in infants, and prevalence of NSP increases to 4 months but diminishes as infants grow older. The majority of cases will have resolved by 2 years of age. Limited head rotation, lower activity levels, and supine sleep position seem to be important determinants.
