One Health Solutions to Obesity in People and Their Pets

Despite the high prevalence of overweight and obesity in the human and companion animal populations, and the global trends for increasing numbers of affected people and pets, there are few successful interventions that are proven to combat this complex multifactorial problem. One key strategy involves effective communication between human and veterinary healthcare professionals with patients and clients about obesity. In human healthcare, the focus of communication should be on physical activity as part of overall health and wellbeing, rather than assessment of the body mass index; clinical examination of patients should record levels of physical activity as a key ‘vital sign’ as part of their assessment. Successful weight loss programmes for companion animals also involves strategic communication with the entire healthcare team leading clients through the ‘stages of change’. There is great potential in employing a ‘One Health’ framework to provide novel solutions for the prevention and treatment of this condition in people and their pets. Comparative clinical research into the biology of obesity and its comorbidities in dogs and cats is likely to lead to knowledge relevant to the equivalent human conditions. The advantages of companion animal clinical research over traditional rodent models include the outbred genetic background and relatively long lifespan of pets and the fact that they share the human domestic environment. The human–companion animal bond can be leveraged to create successful programmes that promote physical activity in people and their pets with obesity. Dog walking is a proven motivator for human physical activity, with health benefits to both the owner and the dog. Realizing the potential of a One Health approach will require the efforts and leadership of a committed group of like-minded individuals representing a range of scientific and medical disciplines. Interested parties will need the means and opportunities to communicate and to collaborate, including having the resources and funding for research. One Health proponents must have a role in forming public policy related to the prevention and management of overweight and obesity

Lipoprotein lipase variants interact with polyunsaturated fatty acids for obesity traits in women: Replication in two populations

BACKGROUND AND AIMS: Lipoprotein lipase (LPL) is a candidate gene for obesity based on its role in triglyceride hydrolysis and the partitioning of fatty acids towards storage or oxidation. Whether dietary fatty acids modify LPL associated obesity risk is unknown. METHODS AND RESULTS: We examined five single nucleotide polymorphisms (SNPs) (rs320, rs2083637, rs17411031, rs13702, rs2197089) for potential interaction with dietary fatty acids for obesity traits in 1171 participants (333 men and 838 women, aged 45–75 y) of the Boston Puerto Rican Health Study (BPRHS). In women, SNP rs320 interacted with dietary polyunsaturated fatty acids (PUFA) for body mass index (BMI) (P = 0.002) and waist circumference (WC) (P = 0.001) respectively. Higher intake of PUFA was associated with lower BMI and WC in homozygotes of the major allele (TT) (P = 0.01 and 0.005) but not in minor allele carriers (TG and GG). These interactions were replicated in an independent population, African American women of the Atherosclerosis Risk in Communities (ARIC) study (n = 1334). CONCLUSION: Dietary PUFA modulated the association of LPL rs320 with obesity traits in two independent populations. These interactions may be relevant to the dietary management of obesity, particularly in women

From theory to policy: reducing harms associated with the weight-centered health paradigm

This article provides an overview of harms associated with public policy promotion of the weight-centered health paradigm and suggests that a shift away from weight-centered health policies is required. Given the evidence about the negative health implications of weight-centric health policies, the objectives are to explore why public policy officials uncritically rely on and promote the weight-centered health paradigm and to propose policy alternatives. Based on findings from discourse analysis of “obesity”-related policy documents, public health policy solutions to the weight-centered health paradigm are proposed and analyzed, drawing from ten key informant interviews with stakeholders working within the policy, academic, and medical contexts
