Kesihatan tulang selepas 50: pencegahan osteoporosis
I. Memahami kesihatan tulang dan osteoporosis
A. Sifat tulang yang dinamik: Tulang bukan struktur statik; Ia adalah tisu yang dinamik dan dinamik yang sentiasa diubahsuai melalui proses yang dipanggil pembentukan semula tulang. Proses ini melibatkan dua jenis sel utama: osteoblast (sel yang membina tulang baru) dan osteoklas (sel yang memecahkan tulang lama). Pada masa mudanya, pembentukan tulang melebihi penyerapan tulang, yang membawa kepada peningkatan jisim tulang dan ketumpatan. Jisim tulang puncak biasanya dicapai sekitar usia 30 tahun. Selepas titik ini, resorpsi tulang secara beransur -ansur mula melampaui pembentukan tulang, yang membawa kepada penurunan semulajadi dalam ketumpatan tulang.
B. Osteoporosis: ancaman senyap: Osteoporosis adalah gangguan rangka yang dicirikan oleh penurunan jisim tulang dan kemerosotan mikroarchitectural tisu tulang, yang membawa kepada peningkatan kerapuhan tulang dan risiko fraktur yang tinggi. Selalunya disebut sebagai “penyakit senyap,” osteoporosis sering berlangsung tanpa gejala yang ketara sehingga patah tulang berlaku. Fraktur ini biasanya menjejaskan pinggul, tulang belakang, dan pergelangan tangan, tetapi boleh berlaku di mana -mana tulang.
C. Kesan penuaan: Seperti yang kita usia, keseimbangan antara pembentukan tulang dan resorpsi beralih ke arah penyerapan. Beberapa faktor menyumbang kepada penurunan ini, termasuk:
1. **Hormonal Changes:** In women, the decline in estrogen levels during menopause significantly accelerates bone loss. Estrogen plays a crucial role in regulating osteoblast and osteoclast activity, and its reduction leads to increased bone resorption. Men also experience a gradual decline in testosterone levels with age, which can contribute to bone loss, although the effect is typically less pronounced than in women.
2. **Decreased Calcium Absorption:** The body's ability to absorb calcium from food decreases with age. This is partly due to reduced levels of vitamin D, which is essential for calcium absorption in the gut.
3. **Reduced Physical Activity:** Physical activity, particularly weight-bearing exercises, stimulates bone formation. A sedentary lifestyle contributes to bone loss.
4. **Medical Conditions and Medications:** Certain medical conditions, such as hyperthyroidism, Cushing's syndrome, and rheumatoid arthritis, can increase the risk of osteoporosis. Similarly, some medications, including corticosteroids (prednisone), certain anticonvulsants, and some proton pump inhibitors (PPIs), can negatively affect bone density.D. Faktor risiko osteoporosis: Mengenal pasti faktor risiko adalah penting untuk campur tangan dan pencegahan awal. Faktor risiko utama termasuk:
1. **Age:** The risk of osteoporosis increases significantly with age, particularly after 50.
2. **Sex:** Women are more likely to develop osteoporosis than men, primarily due to hormonal changes associated with menopause.
3. **Family History:** A family history of osteoporosis or fractures increases your risk. Genetics play a significant role in determining bone density.
4. **Race/Ethnicity:** White and Asian women are at higher risk than Black and Hispanic women.
5. **Body Size:** People with small body frames and low body weight are at higher risk because they have less bone mass to begin with.
6. **Early Menopause:** Early menopause (before age 45) due to natural causes or surgical removal of the ovaries increases the risk of osteoporosis.
7. **Medical Conditions:** As mentioned previously, certain medical conditions increase the risk.
8. **Medications:** Certain medications can contribute to bone loss.
9. **Lifestyle Factors:** Lifestyle factors, such as smoking, excessive alcohol consumption, and a sedentary lifestyle, significantly impact bone health.E. Akibat osteoporosis: Akibat yang paling serius dari osteoporosis adalah patah. Fraktur osteoporotik boleh menyebabkan:
1. **Pain:** Chronic pain is a common consequence of osteoporotic fractures, particularly vertebral fractures.
2. **Disability:** Fractures, especially hip fractures, can lead to significant disability, affecting mobility and independence.
3. **Loss of Height:** Vertebral compression fractures can cause a gradual loss of height and a stooped posture (kyphosis).
4. **Reduced Quality of Life:** The pain, disability, and loss of independence associated with osteoporotic fractures can significantly reduce quality of life.
5. **Increased Mortality:** Hip fractures are particularly serious and are associated with an increased risk of mortality, especially in older adults.Ii. Mencegah osteoporosis: Pendekatan pelbagai rupa
A. Pemakanan: asas kesihatan tulang
1. **Calcium: Building Strong Bones:** Calcium is essential for building and maintaining strong bones. The recommended daily intake of calcium for adults aged 50 and older is 1200 mg.
a. **Dietary Sources:** Prioritize obtaining calcium from dietary sources such as:
* **Dairy Products:** Milk, yogurt, and cheese are excellent sources of calcium. Choose low-fat or non-fat options to minimize saturated fat intake.
* **Leafy Green Vegetables:** Kale, collard greens, and spinach contain calcium, although the bioavailability (the amount that is absorbed and used by the body) may be lower than in dairy products.
* **Fortified Foods:** Many foods are fortified with calcium, including orange juice, cereals, and plant-based milk alternatives (soy milk, almond milk, oat milk).
* **Other Sources:** Tofu (calcium-set), canned sardines and salmon (with bones), almonds, and sesame seeds also contribute to calcium intake.
b. **Calcium Supplements:** If you are unable to meet your calcium needs through diet alone, calcium supplements may be necessary. However, it's important to consult with your doctor or a registered dietitian before taking supplements, as excessive calcium intake can have adverse effects.
* **Types of Calcium Supplements:** Calcium carbonate and calcium citrate are the two most common forms of calcium supplements. Calcium carbonate is best absorbed when taken with food, while calcium citrate can be taken on an empty stomach.
* **Dosage and Timing:** Divide your calcium intake throughout the day, as the body can only absorb a limited amount of calcium at one time (typically 500-600 mg).
* **Potential Side Effects:** Calcium supplements can cause side effects such as constipation, bloating, and gas. Taking smaller doses and drinking plenty of water can help minimize these side effects.
c. **Optimizing Calcium Absorption:** Several factors can affect calcium absorption.
* **Vitamin D:** Vitamin D is essential for calcium absorption in the gut.
* **Oxalates and Phytates:** Oxalates (found in spinach and rhubarb) and phytates (found in whole grains and legumes) can bind to calcium and reduce its absorption. Soaking or cooking these foods can help reduce their oxalate and phytate content.
* **Sodium and Caffeine:** High sodium and caffeine intake can increase calcium excretion in the urine.
2. **Vitamin D: The Calcium Facilitator:** Vitamin D plays a critical role in calcium absorption, bone health, and immune function. The recommended daily intake of vitamin D for adults aged 50 and older is 800-1000 IU (international units).
a. **Sources of Vitamin D:**
* **Sunlight:** The body produces vitamin D when exposed to sunlight. However, the amount of vitamin D produced depends on several factors, including the time of day, season, latitude, skin pigmentation, and sunscreen use.
* **Food:** Few foods are naturally rich in vitamin D. Good sources include fatty fish (salmon, tuna, mackerel), egg yolks, and fortified foods (milk, cereals, orange juice).
* **Supplements:** Vitamin D supplements are often necessary, particularly for people who have limited sun exposure or dietary intake of vitamin D. Vitamin D3 (cholecalciferol) is generally considered to be more effective than vitamin D2 (ergocalciferol).
b. **Vitamin D Deficiency:** Vitamin D deficiency is common, particularly in older adults. Symptoms of vitamin D deficiency can include fatigue, muscle weakness, bone pain, and increased risk of fractures.
c. **Vitamin D Testing:** Your doctor can check your vitamin D levels with a blood test (25-hydroxyvitamin D).
3. **Other Essential Nutrients:** In addition to calcium and vitamin D, other nutrients are important for bone health.
a. **Protein:** Protein is essential for bone formation and repair. Aim for 0.8-1 gram of protein per kilogram of body weight per day. Good sources of protein include lean meats, poultry, fish, beans, lentils, tofu, and nuts.
b. **Vitamin K:** Vitamin K is important for bone mineralization. Good sources of vitamin K include leafy green vegetables, broccoli, and Brussels sprouts.
c. **Magnesium:** Magnesium plays a role in bone metabolism. Good sources of magnesium include whole grains, nuts, seeds, and leafy green vegetables.
d. **Potassium:** Potassium helps neutralize acids in the body, which can help prevent bone loss. Good sources of potassium include fruits and vegetables, such as bananas, potatoes, and spinach.
e. **Vitamin C:** Vitamin C is important for collagen synthesis, which is essential for bone strength. Good sources of vitamin C include citrus fruits, berries, and peppers.
4. **Foods to Limit or Avoid:** Certain foods and beverages can negatively impact bone health.
a. **Excessive Sodium:** High sodium intake can increase calcium excretion in the urine. Limit processed foods, which are often high in sodium.
b. **Excessive Caffeine:** High caffeine intake can also increase calcium excretion. Limit coffee, tea, and soda.
c. **Excessive Alcohol:** Excessive alcohol consumption can interfere with bone formation and increase the risk of fractures. Limit alcohol intake to one drink per day for women and two drinks per day for men.
d. **Phosphoric Acid:** Phosphoric acid, found in some sodas, can interfere with calcium absorption.B. Latihan: Memperkukuhkan tulang dan otot

* All women age 65 and older.
* Men age 70 and older.
* Younger women and men who have risk factors for osteoporosis.
* Anyone who has had a fracture after age 50.
b. **Interpreting DEXA Scan Results:** DEXA scan results are reported as T-scores. A T-score compares your bone density to the average bone density of a healthy young adult of the same sex.
* **Normal Bone Density:** T-score of -1.0 or above.
* **Osteopenia:** T-score between -1.0 and -2.5. Osteopenia indicates lower-than-normal bone density and an increased risk of developing osteoporosis.
* **Osteoporosis:** T-score of -2.5 or below.
c. **Frequency of DEXA Scans:** The frequency of DEXA scans depends on your individual risk factors and bone density. Your doctor can advise you on how often you should be screened.
2. **Medications for Osteoporosis:** Several medications are available to treat osteoporosis and reduce the risk of fractures. These medications work by either slowing down bone resorption or increasing bone formation.
a. **Bisphosphonates:** Bisphosphonates are the most commonly prescribed medications for osteoporosis. They work by slowing down bone resorption.
* **Examples:** Alendronate (Fosamax), risedronate (Actonel), ibandronate (Boniva), zoledronic acid (Reclast).
* **Administration:** Bisphosphonates can be taken orally (daily or weekly) or intravenously (yearly).
* **Potential Side Effects:** Bisphosphonates can cause side effects such as gastrointestinal upset, heartburn, and, in rare cases, osteonecrosis of the jaw and atypical femur fractures.
b. **Selective Estrogen Receptor Modulators (SERMs):** SERMs, such as raloxifene (Evista), mimic the effects of estrogen on bone, helping to slow down bone loss.
* **Administration:** Taken orally, daily.
* **Potential Side Effects:** SERMs can cause side effects such as hot flashes, leg cramps, and an increased risk of blood clots.
c. **Calcitonin:** Calcitonin is a hormone that helps regulate calcium levels in the body and can slow down bone resorption.
* **Administration:** Available as a nasal spray or injection.
* **Potential Side Effects:** Calcitonin can cause side effects such as nasal irritation (with the nasal spray) and nausea.
d. **Parathyroid Hormone (PTH) Analogs:** PTH analogs, such as teriparatide (Forteo) and abaloparatide (Tymlos), stimulate bone formation.
* **Administration:** Administered by daily injection.
* **Potential Side Effects:** PTH analogs can cause side effects such as leg cramps, dizziness, and an increased risk of osteosarcoma (bone cancer) in animal studies.
e. **RANKL Inhibitor:** Denosumab (Prolia) is a RANKL (receptor activator of nuclear factor kappa-B ligand) inhibitor that blocks the activation of osteoclasts, thereby reducing bone resorption.
* **Administration:** Administered by injection every six months.
* **Potential Side Effects:** Denosumab can cause side effects such as back pain, muscle pain, and an increased risk of infections.
f. **Romosozumab:** Romosozumab (Evenity) is a sclerostin inhibitor that increases bone formation and decreases bone resorption.
* **Administration:** Administered by monthly injection for one year.
* **Potential Side Effects:** Romosozumab has a black box warning for increased risk of cardiovascular events (heart attack and stroke).
3. **Working with Your Doctor:** It's essential to work closely with your doctor to develop a comprehensive osteoporosis prevention and treatment plan that is tailored to your individual needs and risk factors. This plan may include lifestyle modifications, nutritional supplements, medications, and regular monitoring of bone density.Iii. Pertimbangan Khas
