SINGLE MOTHERS AT RISK OF POORER HEALTH




Health risks appear to be greatest for single mothers in later life. Single motherhood is associated with an increased risk of multiple health problems, including adverse cardiovascular episodes, poor mental health and increased mortality.


Women who have been single mothers for any period are more at risk of physical disability and poor health in later life in comparison with women who have raised children with a partner. This association is greatest among single mothers in the US, England, Denmark and Sweden. The existence of strong social support in certain countries may explain why the associations are not as strong in some geographic regions. In regions such as Southern Europe, the cultural emphasis placed on family solidarity means that single motherhood is not associated with any increased health risks.

The following women are at particular risk:
  • Those who become single mothers before the age of 20
  • Those who become single mothers through divorce
  • Those who are single mothers for 8 or more years
  • Those who raise two or more children.
These conclusion indicates selection and causation in "cycles of disadvantage." For example, the risk of single motherhood is increased by poverty, which may reflect previous health disadvantages. Being a lone mother may hamper women's abilities to gain education, accrue careers and accumulate income, also leading to poorer health.

ALCOHOL EFFECT IN FIRST 3-4 WEEKS OF PREGNANCY



Alcohol use in early pregnancy may lead to brain changes and changes in gene functioning in other body tissues of offspring. In other words, it may cause lifelong changes to gene regulation in embryonic stem cells - the earliest cells to emerge from a developing embryo.


Alcohol consumption during pregnancy has been linked to increased risk of a number of health conditions for offspring, including growth restriction, intellectual and learning disabilities, poor memory, poor coordination and speech and language delays. However, it is unclear exactly how alcohol exposure during pregnancy impacts fetal development to result in these conditions.


Alcohol-exposed offspring show symptons of Fetal Alcohol Syndrome (FAS) - a condition that is currently difficult to diagnose. These include structural changes to the face and skull, and hyperactivity.

NEARLY ALL AMERICANS HAVE CAVITIES




Virtually all American adults have tooth decay, and more than a quarter have cavities that have not been treated. By the time they hit 65, 96 percent of Americans have tooth decay. It is not what they are doing wrong. It is maybe what they can do better. A lot has to do with access to dentists. People without health insurance coverage for dental care, or living in areas where dentists are not common, are more likely to have tooth decay, and far more likely to go without fillings. About 19 percent of people 65 and over have no teeth at all. This rises to 26 percent of people 75 and older.


Tooth decay is the most common chronic disease in children in the U.S., five times as common as asthma. Caries, which comes from the Latin word for "rotten", is caused mostly by bacteria reacting with sugar in the mouth. They produce acid that leaches minerals from the teeth and weakens them. So it's an infectious disease — one that stays with people for life. Plus there is a genetic susceptibility to developing tooth decay. Fluoride helps slow this loss of minerals and greatly reduces rates of tooth decay.


Although most Americans have tooth decay, the situation is far improved from past generations. Toothbrushing, fluoridation and better dental care have all helped.

STROKE RISING AMONG 'YOUNGER' PEOPLE



There has been a worrying rise in the number of working-age men and women having strokes. Experts say unhealthy lifestyles were partly to blame for the rise, though the growing population and changes to hospital practice also play a part. Strokes should no longer be considered as a disease of the old.
Strokes are caused by blood clots or bleeds to the brain and can lead to long-lasting disability.
The majority occur in people aged over 65, and though rates are decreasing in this group, growing numbers of younger people are at risk. Growing obesity levels, sedentary lives and unhealthy diets - which raise the risks of dangerous blood clots - all play a part.


Alastair Morely was 34 years old when he had a stoke on New Year's Day four years ago: "I had an excruciating headache, was being sick, couldn't walk or talk very well." It was was later found that Mr Morely had a heart condition which had triggered the stroke and after his rehabilitation the solicitor had a phased return to work. "It was tough but I was lucky that I was young and my brain remapped around the damaged area," Mr Morely added.


Pete Rumbold, from Bromsgrove in Worcestershire, was 49 when he had a stroke in November 2011: "It left me paralysed down the left side, unable to speak, swallow or see." He warned that there were no outward signs he was at risk: "I was very fit, in the gym six days a week and I eat healthily, but I had high blood pressure and didn't know about it. I hadn't been to the doctor for seven or eight years so my blood pressure wasn't checked for a long time."


Younger people should be aware of the warning signs such as dizziness, difficulties with speech and changes in the face.



EXCERCISE DELAYS AGE-RELATED HIGH CHOLESTEROL IN MEN


Men who get plenty of aerobic exercise may delay the onset of age-related high cholesterol, potentially lowering their risk for heart disease. Men who can run longer and faster – signs that their bodies more easily deliver oxygen to muscles – also have lower cholesterol.


The benefits of physical fitness in improving cholesterol levels are greatest in young to middle-age adults and tend to decrease gradually with older age. These findings reinforce the importance of young to middle-age men incorporating regular aerobic exercise as part of a healthy lifestyle.


There is very strong evidence that being active is beneficial throughout life not only for cardiovascular disease but for a very large number of chronic diseases and for osteoporosis and fractures. To achieve the fitness levels necessary to ward off age-related high cholesterol, men should get 150 minutes a week of moderate activity or 75 minutes of vigorous activity. These activities might include walking, running, swimming or cycling. It does not matter how old men are when they exercise; they can benefit at any stage. Of course, the younger they start exercise, the later the onset of high cholesterol, especially before 60 years old when cholesterol tends to increase with aging.

WHY YOU ARE CONSTANTLY HUNGRY



Hunger is the physiological need for calories, water, and salt, and it's driven by a mix of factors, including your diet, appetite hormones, and emotional factors, such as stress. Figuring out why you can't stop shoveling it down is important, because excess hunger can tip you off to a physical or mental health issue—and giving in to that need to feed can send your BMI into dangerously unhealthy territory. These 11 things will help explain why your belly's been growling.

1)  You're dehydrated

Mild dehydration is often masked as feelings of hunger, when really your body just needs fluids. The confusion happens in the hypothalamus, the part of the brain that regulates both appetite and thirst. When dehydration sets in, wires get crossed in the hypothalamus, leading you to grab a bag of chips when you really need a bottle of water. Prevent it by staying on top of your fluid intake, starting with a glass of water first thing in the morning. If you feel hungry, and you haven't drank much that day, try drinking a glass of water and waiting 15 to 20 minutes to see if your hunger subsides.

2)  You're a restless sleeper


    Too little sleep can lead to surging levels of ghrelin, a hormone that stimulates appetite, as well as decreased levels of leptin, a hormone that causes feelings of fullness. Lack of shuteye on a regular basis makes you ravenous for another reason. After poor sleep, you're more likely to have serious fatigue and brain fog. Your system, desperate for a shot of energy, triggers cravings for sugar carbs, even if you're not actually hungry. Aim for 7 to 8 hours of sleep a night, and you'll get your energy level and hunger hormones back on track.

    3)  You load up on starchy carbs


    Ever notice how one doughnut or cookie leaves you unable to resist eating another...until the whole box is just crumbs? That's your brain on starchy carbs. Simple carbs, the kind found in sugary, white flour foods like pastries, crackers, and cookies, spike your blood sugar levels quickly, then leave them plunging soon after. That blood sugar plunge causes intense hunger for more sugary carbs, and the cycle continues. Get your carb fix with the complex, filling kind that contains lots of fiber. Almonds, apples, chia seeds, and pistachios are healthy options that ward off hunger pangs.

    4) You're a stress case


    When you're tense, your system ramps up production of the stress hormones adrenaline and cortisol. Elevated levels of these hormones trick your system into thinking it's under attack and needs energy, so your appetite starts raging. Stress also reduces levels of the brain chemical serotonin, and that can make you feel hungry when you aren't. Yoga class or a soothing playlist helps to wade off the effects of stress.

    5)  You drink too much alcohol


    Alcohol stimulates a feeling of hunger even if your stomach is full. People were more likely to consume foods higher in calories after drinking alcohol. And because booze dehydrates you, it can trick you into thinking you need food when your body is really calling for water. Offset the effect by eating before you drink, and make sure to alternate your cocktails with water so you stay hydrated.

    6)  You need to eat more protein


    It sounds counterintuitive, but piling your plate with more food—lean protein and healthy fat, specifically—keeps hunger pangs at bay. Not only does protein stay in your stomach and promote feelings of fullness, it's been shown to have an appetite-suppressing effect. Best sources: Greek yogurt, eggs, lean meat, and whole grains.

    7)  You aren't eating enough fat


    Just like protein, unsaturated fat is also linked to feelings of satiety. When you're satisfied after a meal, you are more likely to listen to your hunger cues and not eat again until you are truly hungry. Add this heart-healthy, brain-boosting kind of fat to your meals in the form of oils, nuts and seeds, and avocados.

    8)  You skip meals


    When you skip a meal and your stomach is empty for too long, it produces an uptick in the hunger hormone ghrelin, which ramps your appetite. Ghrelin also prompts the GI tract to expect food to come. Your ghrelin levels are in overdrive, and so is your lust for food. When you finally give in, you're prone to a binge. As a general rule, try not to let more than 4 to 5 hours go by between meals. And even if you hate breakfast, eat something in the a.m. within an hour of waking, like yogurt, peanut butter and apple slices, or a soymilk smoothie.

    9) You're bombarded by food porn


    With images of food saturating our lives 24-7, it's no wonder so many of us are constantly craving the real thing. Getting a whiff of food has a similar effect. Pleasant food aromas stimulate an involuntary physiological reaction: the mouth will salivate and the stomach will contract, mimicking hunger pangs. Of course, you can't totally eliminate the possibility of seeing or smelling food. But try limiting your exposure, say by skipping TV commercials and un-following food brands on Instagram.

    10)  You inhale your food


    A study published in 2013 in the Journal of Clinical Endocrinology & Metabolism finds that eating at a moderate pace prompts the release of hormones that tell your brain "no more." Try eating your food slowly, savoring each bite and enjoying the ritual of a good meal. Then wait at least 20 minutes before deciding if you really do need another helping. That's about how long it takes for that fullness signal to reach your brain, says Rumsey.

    11)  You're on certain meds


    The same drugs you might be taking regularly to treat a health condition can also drive you to raid the refrigerator. Antidepressants such as Zoloft and Paxil, as well as corticosteroids such as prednisone (prescribed to treat potentially dangerous flareups of the immune system due to allergies, asthma, inflammatory bowel disease like Crohn's disease, and some cancers), are known to affect appetite. If you're on one of these prescription and feel hungry after a normal-sized meal, talk to your doctor to see if it's possible to switch to another drug.
