Guías Dieto Terapéuticas para Personas con Riesgo y/o con Enfermedad Cardiovascular: HTA, Diabetes y Enfermedad Renal Crónica

Objectives

The guideline establishes a national framework for standardised, individualised nutritional care for people at nutritional risk or living with non-communicable chronic diseases, particularly cardiovascular disease, hypertension, diabetes and chronic kidney disease. It aims to help patients meet clinical and therapeutic targets through nutritional assessment, dietary therapy, counselling, education, prevention and continuing follow-up across public and private health services.[1][2][3][4]

• Promote integrated prevention and management of overweight, obesity, dyslipidaemia, metabolic syndrome, hypertension, diabetes, cardiovascular disease and chronic kidney disease through healthier diets, physical activity, weight management, tobacco avoidance and reduced harmful alcohol consumption.[5][6][7]
• Address nutritional risk factors through dietary plans tailored to clinical condition, nutritional status, disease stage, energy and nutrient needs, food preferences, culture, household food availability and food security.[2][8][9][10]
• Support healthy dietary patterns that increase fruit, vegetables, pulses, wholegrains, nuts and other minimally processed foods, while limiting sodium, added sugars, saturated fat, trans fats and highly processed foods.[7][11][12]
• Provide diabetes care that supports individualised glycaemic, weight, blood-pressure and lipid targets, prevents or delays complications, and maintains the pleasure of eating.[8][13]
• Provide chronic kidney disease care that preserves nutritional status, limits nutritional and metabolic complications, delays renal deterioration where possible, and adapts energy, protein, mineral and fluid recommendations to disease stage and dialysis status.[14][15][16][17]
• Promote nutrition and physical activity throughout the life course, including tailored assessment and dietary support for children, adolescents, pregnant women, adults and older people.[18][19][20][21]

Implementation

Implementation is anchored in Nicaragua’s Ministry of Health and the Family and Community Health Model, linking health promotion, primary care and hospital care. The guideline complements standards for comprehensive chronic non-communicable disease care and uses an integrated nutrition-care pathway of screening, assessment, diagnosis, determination of requirements, dietary prescription, intake monitoring, education and follow-up.[22][3][23][24]

• Deliver person-centred nutritional care through nutritionists, doctors and nurses, with nutrition professionals developing dietary plans and other clinical staff supporting follow-up in facilities, families and communities.[2][3]
• Strengthen workforce capacity by disseminating the guideline and training personnel across the health-service network to care for children, adolescents, pregnant women and adults with nutritional risk or chronic disease.[3]
• Use multidisciplinary teams at first and second service levels to provide integrated care for metabolic syndrome, diabetes, cardiovascular disease and chronic kidney disease; second-level nutrition services coordinate therapeutic diets, discharge planning, counselling and counter-referral.[24][25]
• Engage health-establishment staff, Local Systems for Comprehensive Health Care, the Directorate-General for Health Services and technical partners, including the Institute of Nutrition of Central America and Panama, in developing and supporting implementation.[3]
• Provide continuing nutrition education through health facilities, community and patient groups, home visits, schools and family settings, including support for healthier food availability in school kiosks.[18][6][24]
• Plan treatment jointly with patients and families, account for cultural, social and economic circumstances, set achievable short-term goals, and involve relatives and caregivers in food preparation and counselling.[6][26][27]
• Assess clinical and nutritional status using dietary, medical and physical-activity histories, physical examination, anthropometry and relevant laboratory tests, then record findings in clinical records and assessment instruments.[5][28][18]
• Use body mass index, waist circumference, blood pressure, blood glucose, lipid measures and other clinically relevant tests to identify nutritional risk and guide dietary therapy, with assessment adapted for age and pregnancy where applicable.[28][29][30][18]
• Provide diabetes counselling on meal planning, carbohydrate distribution, insulin-to-carbohydrate ratios where relevant, meal timing and physical-activity precautions, including blood-glucose monitoring for people using insulin.[31][32][20][33]
• Apply disease-specific chronic kidney disease management, including nutritional screening, dietary assessment, individualised energy, protein, sodium, potassium, phosphorus and fluid advice, and specialist input for advanced disease or dialysis.[14][34][16][35][36]
• Refer people for medical assessment, treatment review or higher-level care through referral and counter-referral procedures when nutritional problems, clinical manifestations or treatment needs cannot be managed at the current level.[18][25]
• Review dietary plans, nutritional goals and nutritional status periodically, with follow-up intervals adjusted to condition and risk, including regular reassessment for diabetes, dyslipidaemia, cardiovascular disease and chronic kidney disease.[11][37][33][15][34]

Monitoring & Evaluation

Monitoring is principally embedded in individual clinical and nutritional care rather than in a document-wide performance-management system. The guidance requires nutritional screening, assessment, dietary prescription, intake monitoring, education and follow-up for people with nutritional risk, chronic non-communicable diseases and chronic kidney disease.[23][14]It does not set out a unified indicator set, routine reporting architecture, population surveillance system, formal evaluation process or named accountability body.[1][2][20][38]

• Record nutritional findings and classifications in clinical records and assessment instruments, and use referral and counter-referral when medical assessment or treatment review is needed.[18]
• Assess nutritional status, dietary adherence and achievement of individual therapeutic dietary targets, with counselling and follow-up delivered through facilities, families and communities.[2][4]
• Review lifestyle changes, including cholesterol-lowering diets, weight management and physical activity, every four to six months.[19][37]
• Monitor body mass index and waist-to-hip ratio annually for people with normal nutritional status and every three months for people with obesity, and provide six-monthly lifestyle-management follow-up for people with cardiovascular disease.[39]
• Measure glycated haemoglobin at least twice yearly for people meeting stable glycaemic targets and quarterly when treatment changes or targets are not met.[13]
• Monitor blood glucose before, during and after exercise for people using insulin, and reassess people who develop unusual signs during activity.[24][33]

Clinical assessment measures serve as the main operational indicators across cardiovascular and metabolic care. These include blood pressure, anthropometry, body mass index, waist circumference, dietary and physical-activity history, and relevant laboratory tests.[5][28][30]Explicit prevention and management targets include body mass index of 20–25 kg/m², waist circumference below 94 cm for men and 80 cm for women, blood pressure below 140/90 mmHg in the general population and below 130/80 mmHg for people with diabetes, glycated haemoglobin below 7.0%, and cessation of tobacco-smoke exposure.[6]

• Use diabetes risk and diagnostic laboratory thresholds, including fasting glucose, two-hour glucose, glycated haemoglobin and random glucose where clinically indicated.[40][18]
• Assess metabolic syndrome through triglycerides, high-density lipoprotein cholesterol, blood pressure, insulin resistance and fasting glucose, while recognising differences between cited diagnostic frameworks.[30]
• Monitor pregnant women’s nutritional status at every antenatal appointment and use pre-pregnancy or first-trimester nutritional status to guide gestational weight management.[30][11]
• Use daily blood-glucose measurement when assessing insulin-to-carbohydrate ratios and applying insulin-dose calculations.[31]

For chronic kidney disease, monitoring is more explicitly stratified by disease stage, dialysis status, comorbidity and nutritional risk. Classification combines glomerular-filtration categories G1 to G5 with albuminuria categories A1 to A3, and progression includes a sustained annual glomerular-filtration decline of more than 5 ml/min/1.73 m² or a category change with equivalent loss.[41][42]Nutritional and biochemical monitoring covers weight, dietary intake, prealbumin, albumin, lipid profile, glucose measures, uric acid, electrolytes and other markers relevant to renal complications and malnutrition.[43][44][45]

• Review dietary plans, nutritional goals and nutritional status every two months for chronic kidney disease, or more often according to disease stage, comorbidities or emerging abnormalities.[15][26]
• Provide monthly nutrition follow-up for chronic kidney disease grades 3a, 3b and 4, including monitoring of body weight, prealbumin, biochemical parameters, dietary adherence and treatment effectiveness.[34]
• Evaluate biochemical parameters and provide monthly follow-up for children and adolescents with advanced chronic kidney disease, or earlier when clinically required.[46]
• Monitor haemoglobin annually in chronic kidney disease stages 3a and 3b and at least every six months when estimated glomerular filtration rate is below 30 ml/min/1.73 m².[47]
• Use nutritional warning signs, including substantial short-term weight loss, deterioration in body mass index classification, rising creatinine and albumin below 3.5 g/dL, to identify the need for action or referral.[48]

Some laboratory-monitoring frequencies are specified for renal complications. Mineral and bone disorder assessment includes calcium, phosphate, parathyroid hormone, alkaline phosphatase, albumin and, where possible, vitamin D at least twice yearly.[44]The guidance also describes criteria for iron assessment and treatment consideration in chronic kidney disease, but these are clinical decision thresholds rather than programme accountability indicators.[47]

Accountability is therefore primarily clinical and service-based: health personnel document assessments, follow-up dietary plans, coordinate referrals and use multidisciplinary care where specified.[18][24][48]The available extracts do not establish aggregate targets, denominators, data-review responsibilities, public reporting, independent evaluation or consequences for non-performance.[2][34][36]

Costing & Financing

No explicit costing, budget, financing source, resource-mobilisation plan, funding gap, financial allocation or economic assumption is specified in the supplied extracts.[1][2][49][38]The guideline describes resource-intensive clinical inputs, including nutrition personnel, multidisciplinary teams, laboratory testing, counselling, follow-up and referral, but does not attach financial values to them.[24][25][43]

• Provide nutrition services through health personnel, including nutritionists, doctors and nurses, without specifying workforce costs, funding arrangements or resource allocations.[2][24][25]
• Undertake clinical and laboratory monitoring for diabetes, cardiovascular risk and chronic kidney disease without specifying test costs, procurement arrangements or laboratory budgets.[30][13][44]
• Deliver continuing counselling, community and home-based education, and multidisciplinary follow-up without specifying operational funding or implementation timelines.[18][6][48]
• Interpret stated kilocalorie, nutrient, meal-plan and dietary quantities as clinical nutritional parameters rather than financial cost estimates.[19][50][51][52]

The absence of financial information means the extracts do not permit assessment of affordability, fiscal sustainability, unit costs, cost-effectiveness, coverage costs, budget gaps or the funding required to implement the nutritional-care recommendations at scale.[3][49][35]
