More Than a Furry Companion: The Ripple Effect of Companion Animals on Neighborhood Interactions and Sense of Community

Companion animals (pets) exemplify the affinities possible between humans and nonhuman animals. Evidence documenting a diversity of emotional, physical, and therapeutic benefits of pet guardianship (ownership) substantiates sentimental anecdotes from pet owners. Although the literature focuses primarily on the “one to one” benefits accruing from interactions with pets, this paper explores the potential role of pets as facilitators of social interactions and sense of community. Th e paper uses triangulation to synthesize findings from qualitative and quantitative research undertaken in three Western Australian suburbs. Th e qualitative data derive from 12 focus groups and quantitative data, from a survey of 339 residents. In both qualitative and quantitative research, pet ownership positively associated with social interactions, favor exchanges, civic engagement, perceptions of neighborhood friendliness, and sense of community. Pets appeared to ameliorate some determinants of mental health such as loneliness. Findings suggest pets have a ripple effect extending beyond their guardians (owners) to non-pet owners and the broader community. Given the high rates of pet residency in neighborhoods, there is merit in further considering the nexus between pets and community health and well being.

Evaluating risk factors associated with severe hypoglycaemia in epidemiology studies—what method should we use?

Aims  To determine the most appropriate regression models to use when assessing risk factors for severe hypoglycaemia and to investigate the impact of model misspecification and its clinical implications.

Streets Apart: Does Social Capital Vary with Neighbourhood Design?

While neighbourhood differences in social capital have been mapped, few empirical studies have considered the nexus between specific physical characteristics of communities and social capital. In this study we hypothesised that social capital would be positively associated with a more walkable street network design, but inversely associated with negative experiences and perceptions of neighbourhood environments. Data was gathered through a random cross-sectional telephone survey of adults (𝑛=339) from three suburbs with differing street network design. Although there was some relationship between street network layout and social capital, this was not always as hypothesised by previous studies. Perceived incivilities, lower levels of trust and support were among factors that may have countered some of the positive influences of a walkable street network design on social capital. Overall, our findings suggest that the built environment may influence neighbourhood social capital at both a real and perceived level. While the actual presence and type of facilities, neighbourhood design and walkability may impact on social capital formation and maintenance, so too can perceptions of the physical and social environment. Understanding the complex intertwining of physical neighbourhood features, perceptions and social dynamics is relevant to growing public policy interest in strengthening social capital for enhanced community wellbeing.

Early Changes in 24-Hour Ambulatory Blood Pressure are Associated with High Normal Albumin Excretion Rate in Children with Type 1 Diabetes Mellitus

OBJECTIVE The relationship between urinary albumin excretion rate (AER) and elevated blood pressure (BP) is unclear as a cause-effect phenomenon in the development of diabetic nephropathy. The aim of this study was to examine the association between AER, HbA1c and BP in children with normoalbuminuria. METHODS 24-hour ambulatory BP assessment was performed in 78 children with type 1 diabetes mellitus (DM1), age mean +/- SD 13.4 +/- 2.7 yr, range 7.3-18.3 yr, DM1 duration mean +/- SD 6.6 +/- 2.9 yr, range 2.1-11.9 yr. Using generalised linear mixed models with systolic (SBP) and diastolic (DBP) blood pressure as dependent variables, the effects of AER and HbA1c were examined, adjusting for age, gender, DM1 duration and insulin dose. RESULTS Patients with high normal AER (7-20 microg/min) had higher SBP during daytime and night-time compared to the low normal AER (< or = 7 microg/min) (mean +/- SD 118.20 +/- 7.98 and 110.33 +/- 7.08 mm Hg, p = 0.02; mean +/- SD 108.76 +/- 9.21 and 100.20 +/- 7.75 mm Hg, p = 0.03, respectively). DBP was also higher both during day- and night-time when compared to the < or = 7 microg/min group (mean +/- SD 73.40 +/- 6.50 and 64.86 +/- 5.67 mm Hg, p = 0.002; mean +/- SD 62.50 +/- 6.75 and 56.30 +/- 5.56 mm Hg, p = 0.03 day- and night-time, respectively). CONCLUSION A rise in SBP and DBP is associated with increased levels of AER even within the normal range.
