Leave a comment

World Health Statistics 2012 is the World Health Organization’s annual report of health-related data from all 194 WHO member states. The report includes a summary of the progress made towards achieving the health-related Millennium Development Goals and associated targets. This year, it also includes highlight summaries on the topics of noncommunicable diseases, universal health coverage and civil registration coverage.

Select data from the report:

  • Measles deaths declined by 74% between 2000 and 2010.
  • In 2010, 85% of children age 12-23 months worldwide were immunized against measles.
  • Hypertension is considered directly responsible for 7.5 million deaths in 2004–about 12.8% of all global deaths.
  • In Africa, more than one third of people are estimated to have high blood pressure and this condition is increasing.
  • Globally, 2.8 million people die each year as a result of being overweight or obese.
  • Worldwide prevalence of obesity almost doubled between 1980 and 2008.
  • In 2008, 10% of men and 14% of women (half a billion people) in the world were obese.

The report is available in English, French and Spanish.

Using HIV programs to support NCD services

Leave a comment

Although HIV and non-communicable diseases (NCDs) are traditionally thought of as two very different health challenges, some of the systems, tools and approaches developed for HIV programs could be used for NCDs as well, according to an article published in the Journal of Acquired Immune Deficiency Syndromes.

The availability of treatment has transformed HIV into a chronic condition, and local HIV program in low- and middle-income countries have the capability to support continuity care. For example, the appointment books, defaulter tracking, patient counseling, medical records, standardized treatment protocols, referral networks, and linkages to laboratory and pharmacy services available through HIV clinics—and all critical for continuity care—could be used for diabetes and hypertension services.

“Strengthening health systems to deliver continuity care is likely to enhance the performance of both HIV and NCD programs and is a shared priority,” the article concludes.

The UK Department for International Development has made available Type 2 Diabetes, Cardiovascular Disease, Obesity and Hyperlipidaemia Care in Adults: Case Management Desk Guide. This document guides health care workers on the screening, detection and management of type 2 diabetes and its related conditions (hypertension, obesity, high cholesterol, alcoholism and smoking). The guide is currently in draft form.

High blood pressure, high cholesterol and diabetes rates in Switzerland

Leave a comment

High blood pressure, high cholesterol and diabetes rates in Switzerland have increased in the last decade, according to data from three national health surveys conducted in 1997-2007.

The prevalence of self-reported hypertension, hypercholesterolemia and diabetes was 22.1 percent, 11.9 percent and 3.3 percent in 1997, respectively; and increased to 24.1 percent, 17.4 percent and 4.8 percent in 2007.

Self-reported treatment rates among people with these three cardiovascular risk factors also increased from 52.1 percent, 18.5 percent and 50 percent in 1997 to 60.4 percent, 38.8 percent and 53.3 percent in 2007 for hypertension, hypercholesterolemia and diabetes, respectively.

Self-reported control levels increased from 56.4 percent, 52.9 percent and 50 percent in 1997 to 80.6 percent, 75.1 percent and 53.3 percent in 2007. Finally, screening during the last 12 months increased from 84.5 percent, 86.5 percent and 87.4 percent in 1997 to 94 percent, 94.6 percent and 94.1 percent in 2007.

Improving diabetes and hypertension guidelines in Barbados

Leave a comment

A study has shown numerous deficiencies in the quality of hypertension and diabetes primary care in Barbados, despite distribution of regional guidelines.

Current hypertension and diabetes guidelines were considered by some primary health care providers to be outdated, unavailable, difficult to remember and lacking in advice to tackle barriers. Practitioners thought that guidelines should be circulated widely, promoted with repeated educational sessions and kept short. Patient-oriented versions of the guidelines were welcomed.

Patient factors causing barriers to ideal outcome included denial and fear of stigma; financial resources to access an appropriate diet, exercise and monitoring equipment; confusion over medication regimens, not valuing free medication, belief in alternative medicines and being unable to change habits.

System barriers included lack of access to blood investigations, clinic equipment and medication; lack of human resources in polyclinics; and an uncoordinated team approach.

Patients faced cultural barriers with regards to meals, exercise, appropriate body size, footwear, medication taking and taking responsibility for one’s health; and difficulty getting time off work to attend a clinic.

Suggestions for how the health care system could help providers improve the health of those with diabetes and hypertension included educating both the public and persons with the condition, screening programs, providing free home monitors and adequate staffing.

Suggestions for how the wider society could help providers improve the health of those with diabetes and hypertension involved educational outreach to promote family support in managing the condition (cooking, encouraging exercise, giving insulin); a greater role for volunteer groups and retired persons in providing education, support, exercise groups and screening programs; starting associations for hypertension, hyperlipidemia and diabetes; the provision by the government of sidewalks and bicycle lanes for safe exercise; healthy food choices at schools and work places; a tax on unhealthy fast food and an attempt to bring down the cost of healthy food by the government; a requirement that fast food outlets provide healthy alternatives; labeling of all food to include fat, salt and calorie content; encouraging a kitchen garden program; time off by employers to attend appointments; and prominent persons with the disease should speak out to reduce stigma, and give hope that a good life can be had while living with chronic disease.

Famine linked to non-communicable diseases in Nigeria

Leave a comment

Fetal and infant undernutrition is associated with significantly increased risk of hypertension, overweight and impaired glucose tolerance or diabetes among Nigerians who were born during the famine that afflicted the Biafra region of Nigeria during its civil war (1967-1970). Of the one to three million Igbo people that are estimated to have lost their lives during the Nigerian Civil War, only about 10 percent died of military violence. The majority succumbed to starvation.

 Prevention of undernutrition during pregnancy and in infancy should therefore be given high priority in health, education and economic agendas.

Labeling patients as prehypertensive

Leave a comment

Studies have shown that labeling patients as “hypertensive” has some negative effects. But a new study has found that informing patients that they have prehypertension as part of a message designed to prevent hypertension does not seem to be harmful.

However, labeling patients as prehypertensive does not seem to be helpful, either. The study found no evidence that it motivates people to adopt recommended lifestyle changes that help prevent hypertension.

“The most important lesson from this study may be that a clinical strategy currently plays a limited role in the prevention of hypertension,” the study researchers said.

A person’s lifetime risk of hypertension is estimated to be 90 percent in the United States. Therefore, almost all Americans are prehypertensive, according to the study.

Population-level strategies (e.g., sodium reduction in the food and restaurant industry and efforts to combat obesity and physical inactivity) hold much more promise for preventing hypertension.
