Association between Responsible Pet Ownership and Glycemic Control in Youths with Type 1 Diabetes

"In times of stress, it is good to be with them": experience of dog owners from a rural district of Sri Lanka

BACKGROUND

The dog has been man's best companion since ancient times. And, dog ownership is associated with improved physical activity and cardiovascular health. We aim to explore the experience of dog owners on dog ownership and its effects on personal and family health in Anuradhapura, Sri Lanka. Such studies are scarce in developing countries and rural regions.

METHODS

A qualitative study was conducted using in-depth interviews with dog owners in the Anuradhapura district, Sri Lanka. Interviews were tape-recorded and transcribed and thematic analysis was performed.

RESULTS

The study findings were reported under the themes of experience of dog owners, pet dogs for children, village dogs as pets, the role of pet dogs in personal and family health, and participants' advice on dog ownership. Participants highlighted companionship as a positive aspect of pet dogs. However, expenses and reduced travel were the concerns of dog ownership. A child's preference was important in owning a pet dog. Also, participants were willing to adopt the village dogs. Further, they perceived stress reduction and mental satisfaction when interacting with their pet dogs. Moreover, participants seldom experienced major health risks from their pet dogs.

CONCLUSIONS

Human-dog interaction seems to improve the participants' mental well-being, and future research should focus on its possible consequences. Further, the village dogs were adopted as pets. Guided promotion of such activities could ease concerns related to village dogs in developing and rural regions.

Reliability of Trained Dogs to Alert to Hypoglycemia in Patients With Type 1 Diabetes

BACKGROUND

We examined the reliability of trained dogs to alert to hypoglycemia in individuals with type 1 diabetes.

METHODS

Patients with type 1 diabetes who currently used diabetes alert dogs participated in this exploratory study. Subjects reported satisfaction, perceived dog glucose sensing ability and reasons for obtaining a trained dog. Reliability of dog alerts was assessed using capillary blood glucose (CBG) and blinded continuous glucose monitoring (CGM) as comparators in 8 subjects (age 4-48). Hypoglycemia was defined as CBG or CGM <70 mg/dL.

RESULTS

Dog users were very satisfied (8.9/10 on a Likert-type scale) and largely confident (7.9/10) in their dog's ability to detect hypoglycemia. Detection of hypoglycemia was the primary reason for obtaining a trained dog. During hypoglycemia, spontaneous dog alerts occurred at a rate 3.2 (2.0-5.2, 95% CI) times higher than during euglycemia (70-179 mg/dL). Dogs provided timely alerts in 36% (sensitivity) of all hypoglycemia events (n = 45). Due to inappropriate alerts, the PPV of a dog alert for hypoglycemia was 12%. When there was concurrence of a hypoglycemic event between the dog alert and CGM (n = 30), CGM would have alerted prior to the dog in 73% of events (median 22-minute difference).

CONCLUSIONS

This is the first study evaluating reliability of trained dogs to alert to hypoglycemia under real-life conditions. Trained dogs often alert a human companion to otherwise unknown hypoglycemia; however due to high false-positive rate, a dog alert alone is unlikely to be helpful in differentiating hypo-/hyper-/euglycemia. CGM often detects hypoglycemia before a trained dog by a clinically significant margin.
