The sample in the thesis included urban adolescents and adults with both type 1 and type 2 diabetes mellitus. The thesis addressed the following questions: 1. What is the prevalence of diabetes in children in Sub-Saharan Africa (SSA), what are the consequences and risk factors for diabetes and what does diabetes care look like in SSA? (Chapter 2) 2. What are the sources of stress, the ways of coping with stress, the perceived quality of care and the quality of life as experienced by Zambian adolescents living with type 1 diabetes? (Chapter 3) 3. Does the Zambian version of the Problem Areas in Diabetes (PAID) have sound psychometric properties and what are the levels of diabetes-specific emotional distress in people with type 1 and 2 diabetes in Zambia? (Chapter 4) 4. How common is co-morbid depression in individuals with type 1 and 2 diabetes in Zambia? (Chapter 5) 5. What is the association between symptoms of depression with diabetes self-care in individuals with type 1 or 2 diabetes? (Chapter 6) To place this thesis into context, this introduction provides background information about psychosocial issues among people living in diabetes both globally and within the Zambian context. Additionally, an outline of the thesis is provided. 2 Psychosocial issues common in diabetes In 1994, the psychological well-being working group of the World Health Organization/International Diabetes Federation St Vincent Declaration Action Program for Diabetes published guidelines for encouraging psychological well-being in people with diabetes [1]. The guidelines included: improving communication between diabetes health-care teams and the person with diabetes; protecting self-esteem of people with diabetes; responding to individuals’ differing needs; helping patients learn about their own individual responses; helping to motivate self-care; monitoring of psychological well-being and proposing organizational changes aimed at optimizing psychological aspects of diabetes care [1]. 20 years down the line, psychosocial aspects of diabetes are almost never taken care of in the Zambian health care system and there is a dearth of research on the subject in Sub-Saharan Africa. Diabetes is a chronic metabolic disease characterized by hyperglycemia resulting from defects in insulin secretion, insulin action or both [2]. According to the World Health Organization (WHO), diabetes mellitus can be classified into four types: type 1 diabetes, type 2 diabetes, other specific types of diabetes and gestational diabetes mellitus [3].
