A well-planned vegetarian diet can supply all the nutrients that children need for their growth and energy needs. However, those who follow a vegan diet that excludes all meats, poultry, fish, eggs, and dairy foods need to be especially cautious about consuming good sources of vitamins B12 and D. Whole grain foods, fortified cereals and soy milk, and green, leafy vegetables are very important foods for vegans. Fat supplies the body with energy, and helps the body absorb certain nutrients such as vitamins A, D, E, and K.

The objective is to medicine man dispensary buy duricef 500mg with visa foster economically strong and resilient communities which can support community programs that provide basic support for children and families medications bad for liver trusted 500 mg duricef. In exercising this responsibility medications for bipolar disorder generic duricef 500 mg with mastercard, tribal governments rely on collaborations and partnerships with other stakeholders medications ending in ine buy duricef 500mg visa. Because of these relationships, it is critical that tribes and tribal organizations lead the way in developing and implementing sound, culturally appropriate policy strategies to support the healthy development of Native children. Recognizing this need, in 2008, the boards of directors of the National Congress of American Indians, National Indian Health Board, National Indian Education Association, National Indian Child Welfare Association, and the National Council of Urban Indian Health created a joint policy agenda for American Indian and Alaska Native children. This agenda, updated in 2015, is intended to be a tool to develop integrated policy approaches and specific recommendations for tribal governments, policymakers, and local leaders to use when creating and implementing a vision for a thriving, vibrant Native community. It is also intended to guide stakeholders in identifying specific legislative vehicles and policy issues that may affect Native children. This agenda will also inform and guide the work of the emergent initiative- First Kids 1st. Some of these factors are more obvious: children need quality education, supportive communities, and good health. Each of these, however, depends on factors which may be less obviously associated with children, such as access to affordable housing, the availability of healthy foods in communities, and economic development to support community services. Recognizing the challenges that present on the path from prenatal to adulthood, we also must foster resilience in children and youth by ensuring access to both traditional knowledge and new research on life skills which will allow our young people to successfully overcome barriers they may face. In this policy agenda, we identify guiding policy principles for improving the lives of Native children and provide concrete recommendations for implementation. We have grouped these principles into four overarching themes: Healthy Lifestyles, Supportive Environments, Successful Students, and Vibrant Communities. Within each theme, we identify specific areas of focus and set forth specific tribal strategies and policy objectives to improve the lives of Native children and youth. Children who are physically and emotionally healthy are better able to play, learn, and work. Access to Health Care In order to raise healthy children, communities need access to comprehensive quality health care delivered in a culturally appropriate and sensitive manner. Where these innovative programs exist, like the Dental Health Aide Therapy program in Alaska - we see impressive outcomes for community health, patient engagement and workforce development. Develop programs to recruit and train Native people in health professions and to attract skilled health care practitioners to tribal communities, especially in rural and remote areas. For many Native people, culture, tradition, and spirituality are critical to their overall health and well? Modern health care delivery need not, and should not, result in suppression of traditional methods. While health care addresses disease prevention and treatment, wellness encompasses daily lifestyle choices, environment, emotional and spiritual well? For example, a tribal diabetes patient education program, which focuses on teaching people how to manage their disease on a daily basis, is an important tool for reducing diabetes? These programs can also be directed to helping children manage their diabetes from an early age. Similarly, community outreach services can help educate people about the availability of health benefits and teach children to make healthy choices early in life. Behavioral Health & Emotional Well-Being Lack of behavioral health services is a major issue for many tribal communities. The death rate from suicide for American Indian and Alaska Native people is 62% 4 higher than the general population. Unfortunately, the services needed to prevent, diagnose, treat, intervene and provide aftercare for these behavioral health crisis situations does not exist in most tribal health clinics. A 2001 study estimated that the ratio of behavioral health 5 providers to Indian children was as low 1 to 25,000. Children need access to mental health professionals, paraprofessionals, and crisis intervention services in their schools and 4 U. Contextual Issues for Strategic Planning and Evaluation of Systems of Care for American Indian & Alaska Native Communities: An Introduction to Circles of Care. And knowing that protecting youth is a community value, community members and family members need to understand suicide and how to intervene when they fear that a person may be contemplating suicide. Recognize that behavioral health is an important issue for Native communities and support research in the mental health field focusing on culturally appropriate, trauma informed, effective treatment methods and models of care that are feasible for reservation and Alaska Native communities. School counselors should be trained in crisis intervention, provide general counseling services, and be equipped to refer students to other providers for more in? Advocate for tribal provisions that establish direct tribal access to the Community Mental Health Services Block Grant in amounts that reflect the need within tribal communities for mental health services. Healthy Foods Traditional subsistence lifestyles have been replaced with federal programs such as the Food Distribution Program on Indian reservations, the Food Stamp Program, and the Commodity Supplemental Food Program. Additional research shows that longer time spent traveling to purchase groceries can 10 have a direct correlation on high body mass and obesity. Ensure that community food programs, especially youth breakfast and lunch programs, incorporate healthy food choices and locally produced or traditional food options. Written Testimony before the Senate Committee on Health, Education, Labor, and Pensions, Subcommittee on Children and Families. Work to improve the Food Distribution Program on Indian reservations to incorporate more traditional, locally? Exercise habits formed early in life can lay the foundation for healthy exercise habits in adulthood. Creating outlets for healthy physical activity encourages children to be active, and creates opportunities for family and social engagement on a much broader scale. In many tribal communities, however, physical activity options like summer camps and organized sports teams are not readily available to children, and the environment may not be conducive to outdoor play or activity. Work to ensure that schools in Native communities provide comprehensive physical education and organized sports opportunities. Elementary schools should be required to incorporate at least 30 minutes of physical activity a day and should be prohibited from using recess as a form of punishment or reward. Consider incorporating traditional activities and subsistence practices into these programs. Alcohol and Drug Free Communities Alcohol and other drugs pose a significant health risk to Native children. Alcohol is a factor in 12% of all deaths among American Indians and Alaska Natives, which is twice the rate of 12 alcohol? Alcohol and drugs can be dangerous to children even when consumed by other people. For example, children may suffer from fetal alcohol spectrum disorder and may be at an increased risk of child abuse, neglect, or unsafe conditions if a parent drinks. Exposure to drugs and related chemicals can pose a significant threat, such as the risk to children when methamphetamines are manufactured in the home. Comprehensive community-based strategies to combat alcohol and drug abuse amongst youth include varied approaches that include education, familial engagement, alternate activities, and intervention and prevention programming. Alternate activities is a valuable approach in rural areas, where youth can become invested easily in one of few popular extracurricular activities 12 U. Attributable Deaths and Years of Potential Life Lost Among American Indians and Alaska Natives United States, 2001? When youth are involved and invested in positive activities they are less likely to engage in alcohol and substance abuse out of boredom. Additionally, positive options and the relationships that develop through these activities will give children and youth reasons to stay healthy. Create comprehensive, culturally appropriate drug and alcohol screening and treatment programs in Native communities. For example, a tribe may elect to ban alcohol sales, limit sales, or prohibit sales to intoxicated people. Advocate for increased funding for the Department of Justice, Substance Abuse and Mental Health Services Administration, and the Indian Health Service alcohol and drug treatment programs currently serving Native communities. Our children must be protected from unsafe environments and supported by our communities.
