Youth-onset type 2 diabetes mellitus: lessons learned from the TODAY study.

ABSTRACT: Type 2 diabetes mellitus is increasingly diagnosed in obese children and adolescents. Evidence suggests that this disease commonly progresses more rapidly in youth compared with adults and is associated with high rates of early microalbuminuria, hypertension, and dyslipidemia. The Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study was the first multiethnic, multicenter randomized trial in the United States to compare 3 treatment approaches in obese youth with new-onset type 2 diabetes (n=699; ages 10-17 years): monotherapy with metformin, metformin with rosiglitazone, and metformin with an intensive lifestyle intervention. The primary outcome was glycemic control. Diabetes-related complications and cardiovascular risk factors were also examined. Approximately half of the participants could not maintain glycemic control by using metformin alone. Combination therapy with metformin and rosiglitazone resulted in better durability of glycemic control, and metformin plus intensive lifestyle intervention was intermediate but not superior to metformin alone. Deterioration in glycemic control was associated with rapid loss of beta cell function, not worsened insulin sensitivity, and could not be explained by differences in adherence or body mass index. After 3.9 years, 236 (33.8%) of participants had hypertension and 116 participants (16.6%) had microalbuminuria. Only 55.9% of participants had a low-density lipoprotein cholesterol level less than 100 mg/dL (to convert to mmol/L, multiply by 0.0259) after 3 years, and 71 of 517 participants (13.7%) had retinopathy. The significance of the findings from this important trial for the management of youth and young adults with youth-onset type 2 diabetes and its complications is discussed. An aggressive multifaceted approach is needed to prevent or forestall premature microvascular and macrovascular complications in youth-onset type 2 diabetes.

Project description:Conducting longitudinal research related to chronic illness in adolescents is inherently challenging due to developmental changes and psychosocial stressors. Participants in the Treatment Options for type 2 Diabetes in Adolescents and Youth clinical trial were socioeconomically disadvantaged as well. This study assessed attitudes and beliefs about retention in Treatment Options for type 2 Diabetes in Adolescents and Youth to shed light on the factors that potentially promote and detract from the likelihood of sustained participation.After an average 7.3?years of follow-up (range 4.9-9.5), Treatment Options for type 2 Diabetes in Adolescents and Youth participants completed a survey examining their perceptions of the benefits and barriers to sustained involvement in the protocol.The most common reasons for staying in Treatment Options for type 2 Diabetes in Adolescents and Youth included having a strong relationship with the medical team, getting study-provided diabetes care, access to free diabetes medicine and supplies, and being part of a large study to learn more about how to care for youth-onset type 2 diabetes. The most commonly endorsed challenges included scheduling conflicts, possibly disappointing others, difficulties getting to study visits, and the occurrence of other medical issues.Similar to other published reports, a supportive relationship with study staff was commonly endorsed as a benefit of engagement in the longitudinal study, suggesting that rapport, staff consistency, and relationship quality are important components of optimal retention. Moreover, our findings suggest the value of trying to remove logistical barriers, such as transportation and scheduling challenges, in order to promote long-term participation in research. Further research is recommended to evaluate factors that contribute to attrition versus retention in an a priori manner within longitudinal studies, especially protocols involving cohorts that are more vulnerable to attrition due to developmental transitions and/or socioeconomic challenges. Additional efforts to optimize quantitative and qualitative measurement of barriers would also help to expand our understanding of how to optimally retain participants in longitudinal protocols.
