The health-related benefits of dog-ownership in Hong Kong

Background: Numerous studies have found that there are many health-related benefits to owning a dog, however, this has not been investigated in a high dense Asian environment where the culture is very different to Western countries. Objectives: This study aimed at investigating 1) if dog-owners are more active than those who do not own a dog; 2) if dog-owners have higher perceived physical and mental health status compared to a sample of the population who do not own a dog; 3) are there social/environmental factors measured by the Dogs-and-Physical Activity (DAPA) tool that are associated with the perceived physical and mental health as well as physical activity (PA) habits of dog owners. Methods: A total of 102 Chinese dog-owners resident in Hong Kong were recruited to examine what factors might affect dog-owners to walk their dog regularly and hence likely to take part in more daily PA. All of these dog-owners were invited to complete a questionnaire that combined the DAPA-tool, Short-Form-12 health survey (SF-12), and the International-Physical-Activity-Questionnaire – short (IPAQ-short) and to wear an accelerometer for a week. Of the 102 recruited dog-owners, 52 had analysable SF-12 and accelerometry data that could be compared with similar data from 47 HK Chinese who did not own dogs. Linear regression was used to analyse differences between dog-owners and non-dog-owners and to examine social/environmental factors that contributed to physical component score (PCS) and mental component score (MCS) and accrued PA of the dog-owners; their living status, gender, age, Body Mass Index (BMI), income, education level and work status were adjusted during the analysis. Result: Compared to those without dogs, dog-owners were found to have higher PCS scores (P<0.001), involved in more moderate to vigorous PA (MVPA, P=0.02) and overall PA (OVPA, P
