Hypertension is common in children with type 1 diabetes mellitus. Although the exact prevalence of hypertension in pediatric patients with diabetes mellitus is unknown, many studies show rates ranging from 6% to 16%. Several studies looked at the variables that impact blood pressure levels in type 1 diabetes. However, articles in pediatric age group are limited. Upon reviewing the recently published articles, the factors which found to have a significant relationship with blood pressure readings in children with type 1 diabetes mellitus are as follows: patient age, gender, body composition, total fat percentage, body mass index, diabetes duration, glycated hemoglobin levels, and diabetic nephropathy.

| Introduction|| |
Hypertension is one of the most common chronic health problems around the globe, and it’s a well-known and controllable cause of cardiovascular disease and death. Patients with diabetes mellitus (DM) are more likely to have hypertension. Hypertension is common in children with type 1 diabetes (T1DM). Although the exact prevalence of hypertension in pediatric patients with DM is unknown, many studies show rates ranging from 6% to 16%. The prevalence was affected by age and rose among Asian Pacific Islander and American Indian children, but gender was not significantly different.,, In a study done in the US, children with even a single raised blood pressure measurement were found to have a higher chance of acquiring hypertension than adults. For many important reasons, it is critical to identify and manage hypertension in children with type 1 diabetes. Furthermore micro- and macrovascular complications can be prevented in diabetic children by controlling hypertension. Lower blood pressure objectives, preferably 130/80 mm Hg, have been advocated by consensus recommendation committees. Despite the recommendations, hypertension in children with T1DM is still not properly recognized and treated as much as required., This can be attributed to poor screening, the need for repeated measurements, which can lead to delayed diagnosis, and inconvenience with prescribing anti-hypertensive medications in pediatrics.
| Factors Contribute to Elevated Blood Pressure Value in Children With T1DM|| |
The effects of body mass index (BMI) on blood pressure in diabetic children have been extensively studied. Daymen et al. and Pietrzak et al. show a positive correlation between BMI and hypertension in children with T1DM. Overweight and obesity are defined by an excess of total body mass combined with an excess of fat mass. Body fat is now recognized as not just a source of energy but also a very active secreting organ. Adipokines are hormones produced by fat tissue that have a role in insulin sensitivity modulation. Insulin resistance causes arteriosclerosis, which leads to cardiovascular disease, when combined with hyperglycemia, dyslipidemia, and hypertension.
Body composition as a factor linked to increased blood pressure in diabetic patients was investigated by Daymen et al. The body composition which expressed as percentage of each of the followings (Total fat mass, lean body mass, soft tissue fat mass, fat / lean ratio, and abdomen fat and trunk fat) measured by Dual energy X-ray absorptiometry (DEXA) found to have significant effect on development of hypertension in T1DM. Daymen et al. found that abdominal fat percent was the only parameter strongly and significantly related to mean arterial blood pressure and systolic blood pressure (SBP) in the diabetic patients, while diastolic blood pressure (DBP) was affected by abdominal fat %, duration of diabetes and fat/lean ratio in addition to abdominal fat percent. Both Drożdż et al. and Eisenmann et al. found that an increase in body fat mass in healthy children resulted in increased values of both systolic and diastolic blood pressure.
High levels of glycated hemoglobin (HbA1c) may be associated with increased blood pressure in pediatric patients with T1DM. De Oliveira et al. in a descriptive study involved 60 children and adolescents with an established diagnosis of T1DM demonstrated a positive relation of elevated HbA1c levels and development of prehypertension, in their study each 1% increase in HbA1c is associated with an increase of 1.73 mmHg in diastolic blood pressure (DBP). However, Pietrzak et al. found no association between metabolic control as estimated by HbA1c and blood pressure values. An elevated HbA1c levels which reflect poor glycemic control and hyperglycemia had adverse effect on vascular wall function and structure. The consequences of hyperglycemia on the vascular wall have been well documented in the literatures. Hyperglycemia can contribute to the onset of hypertension. Vasoconstriction (through changes in endothelin and nitric oxide) and extracellular matrix deposition can occur as a result of elevated levels of advanced glycation end products, reactive oxygen species, and sorbitol. Protein kinase C activation might be crucial in these processes.,
In addition, elevated HbA1c levels are strongly linked to microvascular problems, such as diabetic nephropathy, which carries a high risk of cardiovascular disease., Microalbuminuria has been linked to greater diastolic blood pressures, whereas better glycemic management (HbA1c less than 7.5%) has been linked to a lower risk of microalbuminuria.
Furthermore, a positive correlation between DBP and diabetes duration was found by Pietrzak et al. with no significant association with systolic blood pressure. With regards to gender, lower systolic blood pressure values were observed among girls than boys, diastolic blood pressure values were comparable in both sexes.
Regarding diabetic nephropathy, prehypertension and hypertension are more prevalent in diabetic patients with microalbuminuria, this is in agreement with studies conducted by Amritanshu et al., who found that development and progression of microalbuminuria is closely linked to hypertension. However; Omar et al.’s  study found no significant difference in the prevalence of hypertension between diabetic patients with or without microalbuminuria. On the contrary, in their study, Rönnback et al. found that type 1 diabetic patients had a greater pulse pressure that increases earlier and more rapidly than the nondiabetic background group, even in the absence of diabetic kidney damage.
| Conclusions|| |
Hypertension in children with T1DM is likely to be more common than previously thought. Blood pressure changes in type 1 diabetes raise the risk of microvascular and macrovascular problems. Several studies looked into the factors that influence blood pressure levels in type 1 diabetes children and adolescents. The age, gender, body composition, total fat percentage, BMI, diabetes duration, glycated hemoglobin (HbA1c) levels, and diabetic nephropathy in type 1 diabetic patients were all found to have a significant relationship with high blood pressure.
